+when one is expected.
+
+=head1 DESCRIPTION
+
+A command-line interface to L<Image::ExifTool|Image::ExifTool>, used for
+reading and writing meta information in a variety of file types. I<FILE> is
+one or more source file names, directory names, or C<-> for the standard
+input. Metadata is read from source files and printed in readable form to
+the console (or written to output text files with B<-w>).
+
+To write or delete metadata, tag values are assigned using
+-I<TAG>=[I<VALUE>], and/or the B<-geotag>, B<-csv=> or B<-json=> options.
+To copy or move metadata, the B<-tagsFromFile> feature is used. By default
+the original files are preserved with C<_original> appended to their names
+-- be sure to verify that the new files are OK before erasing the originals.
+Once in write mode, exiftool will ignore any read-specific options.
+
+Note: If I<FILE> is a directory name then only supported file types in the
+directory are processed (in write mode only writable types are processed).
+However, files may be specified by name, or the B<-ext> option may be used
+to force processing of files with any extension. Hidden files in the
+directory are also processed. Adding the B<-r> option causes subdirectories
+to be processed recursively, but subdirectories with names beginning with
+"." are skipped unless B<-r.> is used.
+
+Below is a list of file types and meta information formats currently
+supported by ExifTool (r = read, w = write, c = create):

+=head1 OPTIONS
+
+Case is not significant for any command-line option (including tag and group
+names), except for single-character options when the corresponding
+upper-case option exists. Many single-character options have equivalent
+long-name versions (shown in brackets), and some options have inverses which
+are invoked with a leading double-dash. Unrecognized options are
+interpreted as tag names (for this reason, multiple single-character options
+may NOT be combined into one argument). Contrary to standard practice,
+options may appear after source file names on the exiftool command line.

+=item B<->I<TAG>
+
+Extract information for the specified tag (eg. C<-CreateDate>). Multiple
+tags may be specified in a single command. A tag name is the handle by
+which a piece of information is referenced. See
+L<Image::ExifTool::TagNames|Image::ExifTool::TagNames> for documentation on
+available tag names. A tag name may include leading group names separated
+by colons (eg. C<-EXIF:CreateDate>, or C<-Doc1:XMP:Creator>), and each group
+name may be prefixed by a digit to specify family number (eg.
+C<-1IPTC:City>). Use the B<-listg> option to list available group names by
+family.
+
+A special tag name of C<All> may be used to indicate all meta information
+(ie. B<-All>). This is particularly useful when a group name is specified
+to extract all information in a group (but beware that unless the B<-a>
+option is also used, some tags in the group may be suppressed by same-named
+tags in other groups). The wildcard characters C<?> and C<*> may be used in
+a tag name to match any single character and zero or more characters
+respectively. These may not be used in a group name, with the exception that
+a group name of C<*> (or C<All>) may be used to extract all instances of a
+tag (as if B<-a> was used). Note that arguments containing wildcards must
+be quoted on the command line of most systems to prevent shell globbing.
+
+A C<#> may be appended to the tag name to disable the print conversion on a
+per-tag basis (see the B<-n> option). This may also be used when writing or
+copying tags.
+
+If no tags are specified, all available information is extracted (as if
+C<-All> had been specified).
+
+Note: Descriptions, not tag names, are shown by default when extracting
+information. Use the B<-s> option to see the tag names instead.
+
+=item B<-->I<TAG>
+
+Exclude specified tag from extracted information. Same as the B<-x> option.
+Group names and wildcards are permitted as described above for B<-TAG>.
+Once excluded from the output, a tag may not be re-included by a subsequent
+option. May also be used following a B<-tagsFromFile> option to exclude
+tags from being copied (when redirecting to another tag, it is the source
+tag that should be excluded), or to exclude groups from being deleted when
+deleting all information (eg. C<-all= --exif:all> deletes all but EXIF
+information). But note that this will not exclude individual tags from a
+group delete (unless a family 2 group is specified, see note 4 below).
+Instead, individual tags may be recovered using the B<-tagsFromFile> option
+(eg. C<-all= -tagsfromfile @ -artist>).
+
+=item B<->I<TAG>[+-^]B<=>[I<VALUE>]
+
+Write a new value for the specified tag (eg. C<-comment=wow>), or delete the
+tag if no I<VALUE> is given (eg. C<-comment=>). C<+=> and C<-=> are used to
+add or remove existing entries from a list, or to shift date/time values
+(see L<Image::ExifTool::Shift.pl|Image::ExifTool::Shift.pl> and note 6 below
+for more details). C<+=> may also be used to increment numerical values (or
+decrement if I<VALUE> is negative), and C<-=> may be used to conditionally
+delete or replace a tag (see L</WRITING EXAMPLES> for examples). C<^=> is
+used to write an empty string instead of deleting the tag when no I<VALUE>
+is given, but otherwise it is equivalent to C<=>.
+
+I<TAG> may contain one or more leading family 0, 1, 2 or 7 group names,
+prefixed by optional family numbers, and separated colons. If no group name
+is specified, the tag is created in the preferred group, and updated in any
+other location where a same-named tag already exists. The preferred group
+is the first group in the following list where I<TAG> is valid: 1) EXIF, 2)
+IPTC, 3) XMP.
+
+The wildcards C<*> and C<?> may be used in tag names to assign the same
+value to multiple tags. When specified with wildcards, "unsafe" tags are
+not written. A tag name of C<All> is equivalent to C<*> (except that it
+doesn't require quoting, while arguments with wildcards do on systems with
+shell globbing), and is often used when deleting all metadata (ie. C<-All=>)
+or an entire group (eg. C<-XMP-dc:All=>, see note 4 below). Note that not
+all groups are deletable, and that the JPEG APP14 "Adobe" group is not
+removed by default with C<-All=> because it may affect the appearance of the
+image. However, color space information is removed, so the colors may be
+affected (but this may be avoided by copying back the tags defined by the
+ColorSpaceTags shortcut). Use the B<-listd> option for a complete list of
+deletable groups, and see note 5 below regarding the "APP" groups. Also,
+within an image some groups may be contained within others, and these groups
+are removed if the containing group is deleted:
+
+ JPEG Image:
+ - Deleting EXIF or IFD0 also deletes ExifIFD, GlobParamIFD,
+ GPS, IFD1, InteropIFD, MakerNotes, PrintIM and SubIFD.
+ - Deleting ExifIFD also deletes InteropIFD and MakerNotes.
+ - Deleting Photoshop also deletes IPTC.
+
+ TIFF Image:
+ - Deleting EXIF only removes ExifIFD which also deletes
+ InteropIFD and MakerNotes.
+
+Notes:
+
+1) B<Many tag values may be assigned in a single command>. If two
+assignments affect the same tag, the latter takes precedence (except for
+list-type tags, for which both values are written).
+
+2) In general, MakerNotes tags are considered "Permanent", and may be edited
+but not created or deleted individually. This avoids many potential
+problems, including the inevitable compatibility problems with OEM software
+which may be very inflexible about the information it expects to find in the
+maker notes.
+
+3) Changes to PDF files by ExifTool are reversible (by deleting the update
+with C<-PDF-update:all=>) because the original information is never actually
+deleted from the file. So ExifTool alone may not be used to securely edit
+metadata in PDF files.
+
+4) Specifying C<-GROUP:all=> deletes the entire group as a block only if a
+single family 0 or 1 group is specified. Otherwise all deletable tags in
+the specified group(s) are removed individually, and in this case is it
+possible to exclude individual tags from a mass delete. For example,
+C<-time:all --Exif:Time:All> removes all deletable Time tags except those in
+the EXIF. This difference also applies if family 2 is specified when
+deleting all groups. For example, C<-2all:all=> deletes tags individually,
+while C<-all:all=> deletes entire blocks.
+
+5) The "APP" group names ("APP0" through "APP15") are used to delete JPEG
+application segments which are not associated with another deletable group.
+For example, specifying C<-APP14:All=> will NOT delete the APP14 "Adobe"
+segment because this is accomplished with C<-Adobe:All>.
+
+6) When shifting a value, the shift is applied to the original value of the
+tag, overriding any other values previously assigned to the tag on the same
+command line. To shift a date/time value and copy it to another tag in the
+same operation, use the B<-globalTimeShift> option.
+
+Special feature: Integer values may be specified in hexadecimal with a
+leading C<0x>, and simple rational values may be specified as fractions.
+
+=item B<->I<TAG>E<lt>=I<DATFILE> or B<->I<TAG>E<lt>=I<FMT>
+
+Set the value of a tag from the contents of file I<DATFILE>. The file name
+may also be given by a I<FMT> string where %d, %f and %e represent the
+directory, file name and extension of the original I<FILE> (see the B<-w>
+option for more details). Note that quotes are required around this
+argument to prevent shell redirection since it contains a C<E<lt>> symbol.
+If I<DATFILE>/I<FMT> is not provided, the effect is the same as C<-TAG=>,
+and the tag is simply deleted. C<+E<lt>=> or C<-E<lt>=> may also be used to
+add or delete specific list entries, or to shift date/time values.
+
+=item B<-tagsFromFile> I<SRCFILE> or I<FMT>
+
+Copy tag values from I<SRCFILE> to I<FILE>. Tag names on the command line
+after this option specify the tags to be copied, or excluded from the copy.
+Wildcards are permitted in these tag names. If no tags are specified, then
+all possible tags (see note 1 below) from the source file are copied to
+same-named tags in the preferred location of the output file (the same as
+specifying C<-all>). More than one B<-tagsFromFile> option may be used to
+copy tags from multiple files.
+
+By default, this option will update any existing and writable same-named
+tags in the output I<FILE>, but will create new tags only in their preferred
+groups. This allows some information to be automatically transferred to the
+appropriate group when copying between images of different formats. However,
+if a group name is specified for a tag then the information is written only
+to this group (unless redirected to another group, see below). If C<All> is
+used as a group name, then the specified tag(s) are written to the same
+family 1 group they had in the source file (ie. the same specific location,
+like ExifIFD or XMP-dc). For example, the common operation of copying all
+writable tags to the same specific locations in the output I<FILE> is
+achieved by adding C<-all:all>. A different family may be specified by
+adding a leading family number to the group name (eg. C<-0all:all> preserves
+the same general location, like EXIF or XMP).
+
+I<SRCFILE> may be the same as I<FILE> to move information around within a
+single file. In this case, C<@> may be used to represent the source file
+(ie. C<-tagsFromFile @>), permitting this feature to be used for batch
+processing multiple files. Specified tags are then copied from each file in
+turn as it is rewritten. For advanced batch use, the source file name may
+also be specified using a I<FMT> string in which %d, %f and %e represent the
+directory, file name and extension of I<FILE>. (eg. the current I<FILE>
+would be represented by C<%d%f.%e>, with the same effect as C<@>). See the
+B<-w> option for I<FMT> string examples.
+
+A powerful redirection feature allows a destination tag to be specified for
+each copied tag. With this feature, information may be written to a tag
+with a different name or group. This is done using
+E<quot>'-I<DSTTAG>E<lt>I<SRCTAG>'E<quot> or
+E<quot>'-I<SRCTAG>E<gt>I<DSTTAG>'E<quot> on the command line after
+B<-tagsFromFile>, and causes the value of I<SRCTAG> to be copied from
+I<SRCFILE> and written to I<DSTTAG> in I<FILE>. Has no effect unless
+I<SRCTAG> exists in I<SRCFILE>. Note that this argument must be quoted to
+prevent shell redirection, and there is no C<=> sign as when assigning new
+values. Source and/or destination tags may be prefixed by a group name
+and/or suffixed by C<#>. Wildcards are allowed in both the source and
+destination tag names. A destination group and/or tag name of C<All> or
+C<*> writes to the same family 1 group and/or tag name as the source. If no
+destination group is specified, the information is written to the preferred
+group. Whitespace around the C<E<gt>> or C<E<lt>> is ignored. As a
+convenience, C<-tagsFromFile @> is assumed for any redirected tags which are
+specified without a prior B<-tagsFromFile> option. Copied tags may also be
+added or deleted from a list with arguments of the form
+E<quot>'-I<SRCTAG>+E<lt>I<DSTTAG>'E<quot> or
+E<quot>'-I<SRCTAG>-E<lt>I<DSTTAG>'E<quot> (but see Note 5 below).
+
+An extension of the redirection feature allows strings involving tag names
+to be used on the right hand side of the C<E<lt>> symbol with the syntax
+E<quot>'-I<DSTTAG>E<lt>I<STR>'E<quot>, where tag names in I<STR> are
+prefixed with a C<$> symbol. See the B<-p> option and the
+L</Advanced formatting feature> section for more details about this syntax.
+Strings starting with a C<=> sign must insert a single space after the
+C<E<lt>> to avoid confusion with the C<E<lt>=> operator which sets the tag
+value from the contents of a file. A single space at the start of the
+string is removed if it exists, but all other whitespace in the string is
+preserved. See note 8 below about using the redirection feature with
+list-type stags, shortcuts or when using wildcards in tag names.
+
+See L</COPYING EXAMPLES> for examples using B<-tagsFromFile>.
+
+Notes:
+
+1) Some tags (generally tags which may affect the appearance of the image)
+are considered "unsafe" to write, and are only copied if specified
+explicitly (ie. no wildcards). See the
+L<tag name documentation|Image::ExifTool::TagNames> for more details about
+"unsafe" tags.
+
+2) Be aware of the difference between excluding a tag from being copied
+(--I<TAG>), and deleting a tag (-I<TAG>=). Excluding a tag prevents it from
+being copied to the destination image, but deleting will remove a
+pre-existing tag from the image.
+
+3) The maker note information is copied as a block, so it isn't affected
+like other information by subsequent tag assignments on the command line,
+and individual makernote tags may not be excluded from a block copy. Also,
+since the PreviewImage referenced from the maker notes may be rather large,
+it is not copied, and must be transferred separately if desired.
+
+4) The order of operations is to copy all specified tags at the point of the
+B<-tagsFromFile> option in the command line. Any tag assignment to the
+right of the B<-tagsFromFile> option is made after all tags are copied. For
+example, new tag values are set in the order One, Two, Three then Four with
+this command:
+
+ exiftool -One=1 -tagsFromFile s.jpg -Two -Four=4 -Three d.jpg
+
+This is significant in the case where an overlap exists between the copied
+and assigned tags because later operations may override earlier ones.
+
+5) The normal behaviour of copied tags differs from that of assigned tags
+for list-type tags and conditional replacements because each copy operation
+on a tag overrides any previous operations. While this avoids duplicate
+list items when copying groups of tags from a file containing redundant
+information, it also prevents values of different tags from being copied
+into the same list when this is the intent. So a B<-addTagsFromFile> option
+is provided which allows copying of multiple tags into the same list. eg)
+
+ exiftool -addtagsfromfile @ '-subject<make' '-subject<model' ...
+
+Similarly, B<-addTagsFromFile> must be used when conditionally replacing a
+tag to prevent overriding earlier conditions.
+
+Other than these differences, the B<-tagsFromFile> and B<-addTagsFromFile>
+options are equivalent.
+
+6) The B<-a> option (allow duplicate tags) is always in effect when copying
+tags from I<SRCFILE>, but the highest priority tag is always copied last so
+it takes precedence.
+
+7) Structured tags are copied by default when copying tags. See the
+B<-struct> option for details.
+
+8) With the redirection feature, copying a tag directly (ie.
+E<quot>'-I<DSTTAG>E<lt>I<SRCTAG>'E<quot>) is not the same as interpolating
+its value inside a string (ie. E<quot>'-I<DSTTAG>E<lt>$I<SRCTAG>'E<quot>)
+for list-type tags, L<shortcut tags|Image::ExifTool::Shortcuts>, tag names
+containing wildcards, or UserParam variables. When copying directly, the
+values of each matching source tag are copied individually to the
+destination tag (as if they were separate assignments). However, when
+interpolated inside a string, list items and the values of shortcut tags are
+concatenated (with a separator set by the B<-sep> option), and wildcards are
+not allowed. Also, UserParam variables are available only when interpolated
+in a string. Another difference is that a minor warning is generated if a
+tag doesn't exist when interpolating its value in a string (with C<$>), but
+isn't when copying the tag directly.
+
+Finally, the behaviour is different when a destination tag or group of
+C<All> is used. When copying directly, a destination group and/or tag name
+of C<All> writes to the same family 1 group and/or tag name as the source.
+But when interpolated in a string, the identity of the source tags are lost
+and the value is written to all possible groups/tags. For example, the
+string form must be used in the following command since the intent is to set
+the value of all existing date/time tags from C<CreateDate>:
+
+ exiftool "-time:all<$createdate" -wm w FILE
+
+=item B<-x> I<TAG> (B<-exclude>)
+
+Exclude the specified tag. There may be multiple B<-x> options. This has
+the same effect as --I<TAG> on the command line. See the --I<TAG>
+documentation above for a complete description.
+
+=back
+
+=head3 Input-output text formatting
+
+Note that trailing spaces are removed from extracted values for most output
+text formats. The exceptions are C<-b>, C<-csv>, C<-j> and C<-X>.
+
+=over 5
+
+=item B<-args> (B<-argFormat>)
+
+Output information in the form of exiftool arguments, suitable for use with
+the B<-@> option when writing. May be combined with the B<-G> option to
+include group names. This feature may be used to effectively copy tags
+between images, but allows the metadata to be altered by editing the
+intermediate file (C<out.args> in this example):
+
+ exiftool -args -G1 --filename --directory src.jpg > out.args
+ exiftool -@ out.args -sep ", " dst.jpg
+
+Note: Be careful when copying information with this technique since it is
+easy to write tags which are normally considered "unsafe". For instance,
+the FileName and Directory tags are excluded in the example above to avoid
+renaming and moving the destination file. Also note that the second command
+above will produce warning messages for any tags which are not writable.
+
+As well, the B<-sep> option should be used as in the second command above to
+maintain separate list items when writing metadata back to image files, and
+the B<-struct> option may be used when extracting to preserve structured XMP
+information.
+
+=item B<-b> (B<-binary>)
+
+Output requested metadata in binary format without tag names or
+descriptions. This option is mainly used for extracting embedded images or
+other binary data, but it may also be useful for some text strings since
+control characters (such as newlines) are not replaced by '.' as they are in
+the default output. By default, list items are separated by a newline when
+extracted with the B<-b> option, but this may be changed (see the B<-sep>
+option for details). May be combined with C<-j>, C<-php> or C<-X> to
+extract binary data in JSON, PHP or XML format, but note that "unsafe" tags
+must be specified explicitly to be extracted as binary in these formats.
+
+=item B<-c> I<FMT> (B<-coordFormat>)
+
+Set the print format for GPS coordinates. I<FMT> uses the same syntax as
+a C<printf> format string. The specifiers correspond to degrees, minutes
+and seconds in that order, but minutes and seconds are optional. For
+example, the following table gives the output for the same coordinate using
+various formats:
+
+ FMT Output
+ ------------------- ------------------
+ "%d deg %d' %.2f"\" 54 deg 59' 22.80" (default for reading)
+ "%d %d %.8f" 54 59 22.80000000 (default for copying)
+ "%d deg %.4f min" 54 deg 59.3800 min
+ "%.6f degrees" 54.989667 degrees
+
+Notes:
+
+1) To avoid loss of precision, the default coordinate format is different
+when copying tags using the B<-tagsFromFile> option.
+
+2) If the hemisphere is known, a reference direction (N, S, E or W) is
+appended to each printed coordinate, but adding a C<+> to the format
+specifier (eg. C<%+.6f>) prints a signed coordinate instead.
+
+3) This print formatting may be disabled with the B<-n> option to extract
+coordinates as signed decimal degrees.
+
+=item B<-charset> [[I<TYPE>=]I<CHARSET>]
+
+If I<TYPE> is C<ExifTool> or not specified, this option sets the ExifTool
+character encoding for output tag values when reading and input values when
+writing, with a default of C<UTF8>. If no I<CHARSET> is given, a list of
+available character sets is returned. Valid I<CHARSET> values are:
+
+ CHARSET Alias(es) Description

+
+I<TYPE> may be C<FileName> to specify the encoding of file names on the
+command line (ie. I<FILE> arguments). In Windows, this triggers use of
+wide-character i/o routines, thus providing support for Unicode file names.
+See the L</WINDOWS UNICODE FILE NAMES> section below for details.
+
+Other values of I<TYPE> listed below are used to specify the internal
+encoding of various meta information formats.
+

+character sets, and the L<Image::ExifTool Options|Image::ExifTool/Options>
+for more details about the B<-charset> settings.
+
+=item B<-csv>[[+]=I<CSVFILE>]
+
+Export information in CSV format, or import information if I<CSVFILE> is
+specified. When importing, the CSV file must be in exactly the same format
+as the exported file. The first row of the I<CSVFILE> must be the ExifTool
+tag names (with optional group names) for each column of the file, and
+values must be separated by commas. A special "SourceFile" column specifies
+the files associated with each row of information (and a SourceFile of "*"
+may be used to define default tags to be imported for all files which are
+combined with any tags specified for the specific SourceFile processed). The
+B<-csvDelim> option may be used to change the input/output field delimiter
+if something other than a comma is required.
+
+The following examples demonstrate basic use of the B<-csv> option:
+
+ # generate CSV file with common tags from all images in a directory
+ exiftool -common -csv dir > out.csv
+
+ # update metadata for all images in a directory from CSV file
+ exiftool -csv=a.csv dir
+
+Empty values are ignored when importing (unless the B<-f> option is used and
+the API MissingTagValue is set to an empty string, in which case the tag is
+deleted). Also, FileName and Directory columns are ignored if they exist
+(ie. ExifTool will not attempt to write these tags with a CSV import). To
+force a tag to be deleted, use the B<-f> option and set the value to "-" in
+the CSV file (or to the MissingTagValue if this API option was used).
+Multiple databases may be imported in a single command.
+
+When exporting a CSV file, the B<-g> or B<-G> option adds group names to the
+tag headings. If the B<-a> option is used to allow duplicate tag names, the
+duplicate tags are only included in the CSV output if the column headings
+are unique. Adding the B<-G4> option ensures a unique column heading for
+each tag. The B<-b> option may be added to output binary data, encoded in
+base64 if necessary (indicated by ASCII "base64:" as the first 7 bytes of
+the value). Values may also be encoded in base64 if the B<-charset> option
+is used and the value contains invalid characters.
+
+When exporting specific tags, the CSV columns are arranged in the same order
+as the specified tags provided the column headings exactly match the
+specified tag names, otherwise the columns are sorted in alphabetical order.
+
+When importing from a CSV file, only files specified on the command line are
+processed. Any extra entries in the CSV file are ignored.
+
+List-type tags are stored as simple strings in a CSV file, but the B<-sep>
+option may be used to split them back into separate items when importing.
+
+Special feature: B<-csv>+=I<CSVFILE> may be used to add items to existing
+lists. This affects only list-type tags. Also applies to the B<-j> option.
+
+Note that this option is fundamentally different than all other output
+format options because it requires information from all input files to be
+buffered in memory before the output is written. This may result in
+excessive memory usage when processing a very large number of files with a
+single command. Also, it makes this option incompatible with the B<-w>
+option. When processing a large number of files, it is recommended to
+either use the JSON (B<-j>) or XML (B<-X>) output format, or use B<-p> to
+generate a fixed-column CSV file instead of using the B<-csv> option.
+
+=item B<-csvDelim> I<STR>
+
+Set the delimiter for separating CSV entries for CSV file input/output via
+the B<-csv> option. I<STR> may contain "\t", "\n", "\r" and "\\" to
+represent TAB, LF, CR and '\' respectively. A double quote is not allowed
+in the delimiter. Default is ','.
+
+=item B<-d> I<FMT> (B<-dateFormat>)
+
+Set the format for date/time tag values. The I<FMT> string may contain
+formatting codes beginning with a percent character (C<%>) to represent the
+various components of a date/time value. The specifics of the I<FMT> syntax
+are system dependent -- consult the C<strftime> man page on your system for
+details. The default format is equivalent to "%Y:%m:%d %H:%M:%S". This
+option has no effect on date-only or time-only tags and ignores timezone
+information if present. Only one B<-d> option may be used per command.
+Requires POSIX::strptime or Time::Piece for the inversion conversion when
+writing.
+
+=item B<-D> (B<-decimal>)
+
+Show tag ID number in decimal when extracting information.
+
+=item B<-E>, B<-ex>, B<-ec> (B<-escapeHTML>, B<-escapeXML>, B<-escapeC>)
+
+Escape characters in output tag values for HTML (B<-E>), XML (B<-ex>) or C
+(B<-ec>). For HTML, all characters with Unicode code points above U+007F
+are escaped as well as the following 5 characters: & (&amp;) E<39> (&#39;)
+E<quot> (&quot;) E<gt> (&gt;) and E<lt> (&lt;). For XML, only these 5
+characters are escaped. The B<-E> option is implied with B<-h>, and B<-ex>
+is implied with B<-X>. For C, all control characters and the backslash are
+escaped. The inverse conversion is applied when writing tags.
+
+=item B<-f> (B<-forcePrint>)
+
+Force printing of tags even if their values are not found. This option only
+applies when specific tags are requested on the command line (ie. not with
+wildcards or by C<-all>). With this option, a dash (C<->) is printed for
+the value of any missing tag, but the dash may be changed via the API
+MissingTagValue option. May also be used to add a 'flags' attribute to the
+B<-listx> output, or to allow tags to be deleted when writing with the
+B<-csv>=I<CSVFILE> feature.
+
+=item B<-g>[I<NUM>][:I<NUM>...] (B<-groupHeadings>)
+
+Organize output by tag group. I<NUM> specifies a group family number, and
+may be 0 (general location), 1 (specific location), 2 (category), 3
+(document number), 4 (instance number), 5 (metadata path), 6 (EXIF/TIFF
+format) or 7 (tag ID). B<-g0> is assumed if a family number is not
+specified. May be combined with other options to add group names to the
+output. Multiple families may be specified by separating them with colons.
+By default the resulting group name is simplified by removing any leading
+C<Main:> and collapsing adjacent identical group names, but this can be
+avoided by placing a colon before the first family number (eg. B<-g:3:1>).
+Use the B<-listg> option to list group names for a specified family. The
+SavePath and SaveFormat API options are automatically enabled if the
+respective family 5 or 6 group names are requested. See the
+L<API GetGroup documentation|Image::ExifTool/GetGroup> for more information.
+
+=item B<-G>[I<NUM>][:I<NUM>...] (B<-groupNames>)
+
+Same as B<-g> but print group name for each tag. B<-G0> is assumed if
+I<NUM> is not specified. May be combined with a number of other options to
+add group names to the output. Note that I<NUM> may be added wherever B<-G>
+is mentioned in the documentation. See the B<-g> option above for details.
+
+=item B<-h> (B<-htmlFormat>)
+
+Use HTML table formatting for output. Implies the B<-E> option. The
+formatting options B<-D>, B<-H>, B<-g>, B<-G>, B<-l> and B<-s> may be used
+in combination with B<-h> to influence the HTML format.
+
+=item B<-H> (B<-hex>)
+
+Show tag ID number in hexadecimal when extracting information.
+
+=item B<-htmlDump>[I<OFFSET>]
+
+Generate a dynamic web page containing a hex dump of the EXIF information.
+This can be a very powerful tool for low-level analysis of EXIF information.
+The B<-htmlDump> option is also invoked if the B<-v> and B<-h> options are
+used together. The verbose level controls the maximum length of the blocks
+dumped. An I<OFFSET> may be given to specify the base for displayed
+offsets. If not provided, the EXIF/TIFF base offset is used. Use
+B<-htmlDump0> for absolute offsets. Currently only EXIF/TIFF and JPEG
+information is dumped, but the -u option can be used to give a raw hex dump
+of other file formats.
+
+=item B<-j>[[+]=I<JSONFILE>] (B<-json>)
+
+Use JSON (JavaScript Object Notation) formatting for console output, or
+import JSON file if I<JSONFILE> is specified. This option may be combined
+with B<-g> to organize the output into objects by group, or B<-G> to add
+group names to each tag. List-type tags with multiple items are output as
+JSON arrays unless B<-sep> is used. By default XMP structures are flattened
+into individual tags in the JSON output, but the original structure may be
+preserved with the B<-struct> option (this also causes all list-type XMP
+tags to be output as JSON arrays, otherwise single-item lists would be
+output as simple strings). The B<-a> option is implied if the B<-g> or
+B<-G> options are used, otherwise it is ignored and tags with identical
+JSON names are suppressed. (B<-g4> may be used to ensure that all tags have
+unique JSON names.) Adding the B<-D> or B<-H> option changes tag values to
+JSON objects with "val" and "id" fields, and adding B<-l> adds a "desc"
+field, and a "num" field if the numerical value is different from the
+converted "val". The B<-b> option may be added to output binary data,
+encoded in base64 if necessary (indicated by ASCII "base64:" as the first 7
+bytes of the value), and B<-t> may be added to include tag table information
+(see B<-t> for details). The JSON output is UTF-8 regardless of any B<-L>
+or B<-charset> option setting, but the UTF-8 validation is disabled if a
+character set other than UTF-8 is specified.
+
+If I<JSONFILE> is specified, the file is imported and the tag definitions
+from the file are used to set tag values on a per-file basis. The special
+"SourceFile" entry in each JSON object associates the information with a
+specific target file. An object with a missing SourceFile or a SourceFile
+of "*" defines default tags for all target files which are combined with any
+tags specified for the specific SourceFile processed. The imported JSON
+file must have the same format as the exported JSON files with the exception
+that the B<-g> option is not compatible with the import file format (use
+B<-G> instead). Additionally, tag names in the input JSON file may be
+suffixed with a C<#> to disable print conversion.
+
+Unlike CSV import, empty values are not ignored, and will cause an empty
+value to be written if supported by the specific metadata type. Tags are
+deleted by using the B<-f> option and setting the tag value to "-" (or to
+the MissingTagValue setting if this API option was used). Importing with
+B<-j>+=I<JSONFILE> causes new values to be added to existing lists.
+
+=item B<-l> (B<-long>)
+
+Use long 2-line Canon-style output format. Adds a description and
+unconverted value (if it is different from the converted value) to the XML,
+JSON or PHP output when B<-X>, B<-j> or B<-php> is used. May also be
+combined with B<-listf>, B<-listr> or B<-listwf> to add descriptions of the
+file types.
+
+=item B<-L> (B<-latin>)
+
+Use Windows Latin1 encoding (cp1252) for output tag values instead of the
+default UTF-8. When writing, B<-L> specifies that input text values are
+Latin1 instead of UTF-8. Equivalent to C<-charset latin>.
+
+=item B<-lang> [I<LANG>]
+
+Set current language for tag descriptions and converted values. I<LANG> is
+C<de>, C<fr>, C<ja>, etc. Use B<-lang> with no other arguments to get a
+list of available languages. The default language is C<en> if B<-lang> is
+not specified. Note that tag/group names are always English, independent of
+the B<-lang> setting, and translation of warning/error messages has not yet
+been implemented. May also be combined with B<-listx> to output
+descriptions in one language only.
+
+By default, ExifTool uses UTF-8 encoding for special characters, but the
+the B<-L> or B<-charset> option may be used to invoke other encodings. Note
+that ExifTool uses Unicode::LineBreak if available to help preserve the
+column alignment of the plain text output for languages with a
+variable-width character set.
+
+Currently, the language support is not complete, but users are welcome to
+help improve this by submitting their own translations. To submit a
+translation, follow these steps (you must have Perl installed for this):
+
+1. Download and unpack the latest Image-ExifTool full distribution.
+
+2. 'cd' into the Image-ExifTool directory.
+
+3. Run this command to make an XML file of the desired tags (eg. EXIF):
+
+ ./exiftool -listx -exif:all > out.xml
+
+4. Copy this text into a file called 'import.pl' in the exiftool directory:
+
+ push @INC, 'lib';
+ require Image::ExifTool::TagInfoXML;
+ my $file = shift or die "Expected XML file name\n";
+ $Image::ExifTool::TagInfoXML::makeMissing = shift;
+ Image::ExifTool::TagInfoXML::BuildLangModules($file,8);
+
+5. Run the 'import.pl' script to Import the XML file, generating the
+'MISSING' entries for your language (eg. Russian):
+
+ perl import.pl out.xml ru
+
+6. Edit the generated language module lib/Image/ExifTool/Lang/ru.pm, and
+search and replace all 'MISSING' strings in the file with your translations.
+
+7. Email the module ('ru.pm' in this example) to philharvey66 at gmail.com
+
+8. Thank you!!
+
+=item B<-listItem> I<INDEX>
+
+For list-type tags, this causes only the item with the specified index to be
+extracted. I<INDEX> is 0 for the first item in the list. Negative indices
+may also be used to reference items from the end of the list. Has no effect
+on single-valued tags. Also applies to tag values when copying from a tag,
+and in B<-if> conditions.
+
+=item B<-n> (B<--printConv>)
+
+Disable print conversion for all tags. By default, extracted values are
+converted to a more human-readable format, but the B<-n> option disables
+this conversion, revealing the machine-readable values. For example:
+
+ > exiftool -Orientation -S a.jpg
+ Orientation: Rotate 90 CW
+ > exiftool -Orientation -S -n a.jpg
+ Orientation: 6
+
+The print conversion may also be disabled on a per-tag basis by suffixing
+the tag name with a C<#> character:
+
+ > exiftool -Orientation# -Orientation -S a.jpg
+ Orientation: 6
+ Orientation: Rotate 90 CW
+
+These techniques may also be used to disable the inverse print conversion
+when writing. For example, the following commands all have the same effect:
+
+ > exiftool -Orientation='Rotate 90 CW' a.jpg
+ > exiftool -Orientation=6 -n a.jpg
+ > exiftool -Orientation#=6 a.jpg
+
+=item B<-p> I<FMTFILE> or I<STR> (B<-printFormat>)
+
+Print output in the format specified by the given file or string. The
+argument is interpreted as a string unless a file of that name exists, in
+which case the string is loaded from the contents of the file. Tag names in
+the format file or string begin with a C<$> symbol and may contain leading
+group names and/or a trailing C<#> (to disable print conversion). Case is
+not significant. Braces C<{}> may be used around the tag name to separate
+it from subsequent text. Use C<$$> to represent a C<$> symbol, and C<$/>
+for a newline.
+
+Multiple B<-p> options may be used, each contributing a line (or more) of
+text to the output. Lines beginning with C<#[HEAD]> and C<#[TAIL]> are
+output before the first processed file and after the last processed file
+respectively. Lines beginning with C<#[SECT]> and C<#[ENDS]> are output
+before and after each section of files. A section is defined as a group of
+consecutive files with the same section header (eg. files are grouped by
+directory if C<#[SECT]> contains C<$directory>). Lines beginning with
+C<#[BODY]> and lines not beginning with C<#> are output for each processed
+file. Lines beginning with C<#[IF]> are not output, but all BODY lines are
+skipped if any tag on an IF line doesn't exist. Other lines beginning with
+C<#> are ignored. For example, this format file:
+
+ # this is a comment line
+ #[HEAD]-- Generated by ExifTool $exifToolVersion --
+ File: $FileName - $DateTimeOriginal
+ (f/$Aperture, ${ShutterSpeed}s, ISO $EXIF:ISO)
+ #[TAIL]-- end --
+
+with this command:
+
+ exiftool -p test.fmt a.jpg b.jpg
+
+produces output like this:
+
+ -- Generated by ExifTool 12.12 --
+ File: a.jpg - 2003:10:31 15:44:19
+ (f/5.6, 1/60s, ISO 100)
+ File: b.jpg - 2006:05:23 11:57:38
+ (f/8.0, 1/13s, ISO 100)
+ -- end --
+
+The values of List-type tags with multiple items and Shortcut tags
+representing multiple tags are joined according the the B<-sep> option
+setting when interpolated in the string.
+
+When B<-ee> (B<-extractEmbedded>) is combined with B<-p>, embedded documents
+are effectively processed as separate input files.
+
+If a specified tag does not exist, a minor warning is issued and the line
+with the missing tag is not printed. However, the B<-f> option may be used
+to set the value of missing tags to '-' (but this may be configured via the
+MissingTagValue API option), or the B<-m> option may be used to ignore minor
+warnings and leave the missing values empty. Alternatively, B<-q -q> may be
+used to simply suppress the warning messages.
+
+The L</Advanced formatting feature> may be used to modify the values of
+individual tags with the B<-p> option.
+
+=item B<-php>
+
+Format output as a PHP Array. The B<-g>, B<-G>, B<-D>, B<-H>, B<-l>,
+B<-sep> and B<-struct> options combine with B<-php>, and duplicate tags are
+handled in the same way as with the B<-json> option. As well, the B<-b>
+option may be added to output binary data, and B<-t> may be added to include
+tag table information (see B<-t> for details). Here is a simple example
+showing how this could be used in a PHP script:
+
+ <?php
+ eval('$array=' . `exiftool -php -q image.jpg`);
+ print_r($array);
+ ?>
+
+=item B<-s>[I<NUM>] (B<-short>)
+
+Short output format. Prints tag names instead of descriptions. Add I<NUM>
+or up to 3 B<-s> options for even shorter formats:
+
+ -s1 or -s - print tag names instead of descriptions
+ -s2 or -s -s - no extra spaces to column-align values
+ -s3 or -s -s -s - print values only (no tag names)
+
+Also effective when combined with B<-t>, B<-h>, B<-X> or B<-listx> options.
+
+=item B<-S> (B<-veryShort>)
+
+Very short format. The same as B<-s2> or two B<-s> options. Tag names are
+printed instead of descriptions, and no extra spaces are added to
+column-align values.
+
+=item B<-sep> I<STR> (B<-separator>)
+
+Specify separator string for items in list-type tags. When reading, the
+default is to join list items with ", ". When writing, this option causes
+values assigned to list-type tags to be split into individual items at each
+substring matching I<STR> (otherwise they are not split by default). Space
+characters in I<STR> match zero or more whitespace characters in the value.
+
+Note that an empty separator ("") is allowed, and will join items with no
+separator when reading, or split the value into individual characters when
+writing.
+
+For pure binary output (B<-b> used without B<-j>, B<-php> or B<-X>), the
+first B<-sep> option specifies a list-item separator, and a second B<-sep>
+option specifies a terminator for the end of the list (or after each value
+if not a list). In these strings, C<\n>, C<\r> and C<\t> may be used to
+represent a newline, carriage return and tab respectively. By default,
+binary list items are separated by a newline, and no terminator is added.
+
+=item B<-sort>, B<--sort>
+
+Sort output by tag description, or by tag name if the B<-s> option is used.
+When sorting by description, the sort order will depend on the B<-lang>
+option setting. Without the B<-sort> option, tags appear in the order they
+were specified on the command line, or if not specified, the order they were
+extracted from the file. By default, tags are organized by groups when
+combined with the B<-g> or B<-G> option, but this grouping may be disabled
+with B<--sort>.
+
+=item B<-struct>, B<--struct>
+
+Output structured XMP information instead of flattening to individual tags.
+This option works well when combined with the XML (B<-X>) and JSON (B<-j>)
+output formats. For other output formats, XMP structures and lists are
+serialized into the same format as when writing structured information (see
+L<https://exiftool.org/struct.html> for details). When copying, structured
+tags are copied by default unless B<--struct> is used to disable this
+feature (although flattened tags may still be copied by specifying them
+individually unless B<-struct> is used). These options have no effect when
+assigning new values since both flattened and structured tags may always be
+used when writing.
+
+=item B<-t> (B<-tab>)
+
+Output a tab-delimited list of description/values (useful for database
+import). May be combined with B<-s> to print tag names instead of
+descriptions, or B<-S> to print tag values only, tab-delimited on a single
+line. The B<-t> option may be combined with B<-j>, B<-php> or B<-X> to add
+tag table information (C<table>, tag C<id>, and C<index> for cases where
+multiple conditional tags exist with the same ID).
+
+=item B<-T> (B<-table>)
+
+Output tag values in table form. Equivalent to B<-t -S -q -f>.
+
+=item B<-v>[I<NUM>] (B<-verbose>)
+
+Print verbose messages. I<NUM> specifies the level of verbosity in the
+range 0-5, with higher numbers being more verbose. If I<NUM> is not given,
+then each B<-v> option increases the level of verbosity by 1. With any
+level greater than 0, most other options are ignored and normal console
+output is suppressed unless specific tags are extracted. Using B<-v0>
+causes the console output buffer to be flushed after each line (which may be
+useful to avoid delays when piping exiftool output), and prints the name of
+each processed file when writing. Also see the B<-progress> option.
+
+=item B<-w>[+|!] I<EXT> or I<FMT> (B<-textOut>)
+
+Write console output to files with names ending in I<EXT>, one for each
+source file. The output file name is obtained by replacing the source file
+extension (including the '.') with the specified extension (and a '.' is
+added to the start of I<EXT> if it doesn't already contain one).
+Alternatively, a I<FMT> string may be used to give more control over the
+output file name and directory. In the format string, %d, %f and %e
+represent the directory, filename and extension of the source file, and %c
+represents a copy number which is automatically incremented if the file
+already exists. %d includes the trailing '/' if necessary, but %e does not
+include the leading '.'. For example:
+
+ -w %d%f.txt # same effect as "-w txt"
+ -w dir/%f_%e.out # write files to "dir" as "FILE_EXT.out"
+ -w dir2/%d%f.txt # write to "dir2", keeping dir structure
+ -w a%c.txt # write to "a.txt" or "a1.txt" or "a2.txt"...
+
+Existing files will not be changed unless an exclamation point is added to
+the option name (ie. B<-w!> or B<-textOut!>) to overwrite the file, or a
+plus sign (ie. B<-w+> or B<-textOut+>) to append to the existing file. Both
+may be used (ie. B<-w+!> or B<-textOut+!>) to overwrite output files that
+didn't exist before the command was run, and append the output from multiple
+source files. For example, to write one output file for all source files in
+each directory:
+
+ exiftool -filename -createdate -T -w+! %d/out.txt -r DIR
+
+Capitalized format codes %D, %F, %E and %C provide slightly different
+alternatives to the lower case versions. %D does not include the trailing
+'/', %F is the full filename including extension, %E includes the leading
+'.', and %C increments the count for each processed file (see below).
+
+Notes:
+
+1) In a Windows BAT file the C<%> character is represented by C<%%>, so an
+argument like C<%d%f.txt> is written as C<%%d%%f.txt>.
+
+2) If the argument for B<-w> does not contain a valid format code (eg. %f),
+then it is interpreted as a file extension. It is not possible to specify a
+simple filename as an argument -- creating a single output file from
+multiple source files is typically done by shell redirection, ie)
+
+ exiftool FILE1 FILE2 ... > out.txt
+
+But if necessary, an empty format code may be used to force the argument to
+be interpreted as a format string, and the same result may be obtained
+without the use of shell redirection:
+
+ exiftool -w+! %0fout.txt FILE1 FILE2 ...
+
+Advanced features:
+
+A substring of the original file name, directory or extension may be taken
+by specifying a field width immediately following the '%' character. If the
+width is negative, the substring is taken from the end. The substring
+position (characters to ignore at the start or end of the string) may be
+given by a second optional value after a decimal point. For example:
+
+ Input File Name Format Specifier Output File Name
+ ---------------- ---------------- ----------------
+ Picture-123.jpg %7f.txt Picture.txt
+ Picture-123.jpg %-.4f.out Picture.out
+ Picture-123.jpg %7f.%-3f Picture.123
+ Picture-123a.jpg Meta%-3.1f.txt Meta123.txt
+
+(Note that special characters may have a width of greater than one.)
+
+For %d and %D, the field width/position specifiers may be applied to the
+directory levels instead of substring position by using a colon instead of a
+decimal point in the format specifier. For example:
+
+ Source Dir Format Result Notes
+ ------------ ------ ---------- ------------------
+ pics/2012/02 %2:d pics/2012/ take top 2 levels
+ pics/2012/02 %-:1d pics/2012/ up one directory level
+ pics/2012/02 %:1d 2012/02/ ignore top level
+ pics/2012/02 %1:1d 2012/ take 1 level after top
+ pics/2012/02 %-1:D 02 bottom level folder name
+ /Users/phil %:2d phil/ ignore top 2 levels
+
+(Note that the root directory counts as one level when an absolute path is
+used as in the last example above.)
+
+For %c, these modifiers have a different effects. If a field width is
+given, the copy number is padded with zeros to the specified width. A
+leading '-' adds a dash before the copy number, and a '+' adds an underline.
+By default, the copy number is omitted from the first file of a given name,
+but this can be changed by adding a decimal point to the modifier. For
+example:
+
+ -w A%-cZ.txt # AZ.txt, A-1Z.txt, A-2Z.txt ...
+ -w B%5c.txt # B.txt, B00001.txt, B00002.txt ...
+ -w C%.c.txt # C0.txt, C1.txt, C2.txt ...
+ -w D%-.c.txt # D-0.txt, D-1.txt, D-2.txt ...
+ -w E%-.4c.txt # E-0000.txt, E-0001.txt, E-0002.txt ...
+ -w F%-.4nc.txt # F-0001.txt, F-0002.txt, F-0003.txt ...
+ -w G%+c.txt # G.txt, G_1.txt G_2.txt ...
+ -w H%-lc.txt # H.txt, H-b.txt, H-c.txt ...
+ -w I.%.3uc.txt # I.AAA.txt, I.AAB.txt, I.AAC.txt ...
+
+A special feature allows the copy number to be incremented for each
+processed file by using %C (upper case) instead of %c. This allows a
+sequential number to be added to output file names, even if the names are
+different. For %C, a copy number of zero is not omitted as it is with %c.
+A leading '-' causes the number to be reset at the start of each new
+directory, and '+' has no effect. The number before the decimal place gives
+the starting index, the number after the decimal place gives the field
+width. The following examples show the output filenames when used with the
+command C<exiftool rose.jpg star.jpg jet.jpg ...>:
+
+ -w %C%f.txt # 0rose.txt, 1star.txt, 2jet.txt
+ -w %f-%10C.txt # rose-10.txt, star-11.txt, jet-12.txt
+ -w %.3C-%f.txt # 000-rose.txt, 001-star.txt, 002-jet.txt
+ -w %57.4C%f.txt # 0057rose.txt, 0058star.txt, 0059jet.txt
+
+All format codes may be modified by 'l' or 'u' to specify lower or upper
+case respectively (ie. C<%le> for a lower case file extension). When used
+to modify %c or %C, the numbers are changed to an alphabetical base (see
+example H above). Also, %c and %C may be modified by 'n' to count using
+natural numbers starting from 1, instead of 0 (see example F above).
+
+This same I<FMT> syntax is used with the B<-o> and B<-tagsFromFile> options,
+although %c and %C are only valid for output file names.
+
+=item B<-W>[+|!] I<FMT> (B<-tagOut>)
+
+This enhanced version of the B<-w> option allows a separate output file to
+be created for each extracted tag. See the B<-w> option documentation above
+for details of the basic functionality. Listed here are the differences
+between B<-W> and B<-w>:
+
+1) With B<-W>, a new output file is created for each extracted tag.
+
+2) B<-W> supports three additional format codes: %t, %g and %s represent
+the tag name, group name, and suggested extension for the output file (based
+on the format of the data). The %g code may be followed by a single digit
+to specify the group family number (eg. %g1), otherwise family 0 is assumed.
+The substring width/position/case specifiers may be used with these format
+codes in exactly the same way as with %f and %e.
+
+3) The argument for B<-W> is interpreted as a file name if it contains no
+format codes. (For B<-w>, this would be a file extension.) This change
+allows a simple file name to be specified, which, when combined with the
+append feature, provides a method to write metadata from multiple source
+files to a single output file without the need for shell redirection. For
+example, the following pairs of commands give the same result:
+
+ # overwriting existing text file
+ exiftool test.jpg > out.txt # shell redirection
+ exiftool test.jpg -W+! out.txt # equivalent -W option
+
+ # append to existing text file
+ exiftool test.jpg >> out.txt # shell redirection
+ exiftool test.jpg -W+ out.txt # equivalent -W option
+
+4) Adding the B<-v> option to B<-W> sends a list of the tags and output file
+names to the console instead of giving a verbose dump of the entire file.
+(Unless appending all output to one file for each source file by using
+B<-W+> with an output file I<FMT> that does not contain %t, $g or %s.)
+
+5) Individual list items are stored in separate files when B<-W> is combined
+with B<-b>, but note that for separate files to be created %c or %C must be
+used in I<FMT> to give the files unique names.
+
+=item B<-Wext> I<EXT>, B<--Wext> I<EXT> (B<-tagOutExt>)
+
+This option is used to specify the type of output file(s) written by the
+B<-W> option. An output file is written only if the suggested extension
+matches I<EXT>. Multiple B<-Wext> options may be used to write more than
+one type of file. Use B<--Wext> to write all but the specified type(s).
+
+=item B<-X> (B<-xmlFormat>)
+
+Use ExifTool-specific RDF/XML formatting for console output. Implies the
+B<-a> option, so duplicate tags are extracted. The formatting options
+B<-b>, B<-D>, B<-H>, B<-l>, B<-s>, B<-sep>, B<-struct> and B<-t> may be used
+in combination with B<-X> to affect the output, but note that the tag ID
+(B<-D>, B<-H> and B<-t>), binary data (B<-b>) and structured output
+(B<-struct>) options are not effective for the short output (B<-s>). Another
+restriction of B<-s> is that only one tag with a given group and name may
+appear in the output. Note that the tag ID options (B<-D>, B<-H> and B<-t>)
+will produce non-standard RDF/XML unless the B<-l> option is also used.
+
+By default, B<-X> outputs flattened tags, so B<-struct> should be added if
+required to preserve XMP structures. List-type tags with multiple values
+are formatted as an RDF Bag, but they are combined into a single string when
+B<-s> or B<-sep> is used. Using B<-L> changes the XML encoding from "UTF-8"
+to "windows-1252". Other B<-charset> settings change the encoding only if
+there is a corresponding standard XML character set. The B<-b> option
+causes binary data values to be written, encoded in base64 if necessary.
+The B<-t> option adds tag table information to the output (see B<-t> for
+details).
+
+Note: This output is NOT the same as XMP because it uses
+dynamically-generated property names corresponding to the ExifTool tag
+names, and not the standard XMP properties. To write XMP instead, use the
+B<-o> option with an XMP extension for the output file.

+
+=item B<-a>, B<--a> (B<-duplicates>, B<--duplicates>)
+
+Allow (B<-a>) or suppress (B<--a>) duplicate tag names to be extracted. By
+default, duplicate tags are suppressed when reading unless the B<-ee> or
+B<-X> options are used or the Duplicates option is enabled in the
+configuration file. This option has an affect when writing only to allow
+duplicate Warning messages to be shown. Duplicate tags are always extracted
+when copying.
+
+=item B<-e> (B<--composite>)
+
+Extract existing tags only -- don't generate composite tags.
+
+=item B<-ee> (B<-extractEmbedded>)
+
+Extract information from embedded documents in EPS files, embedded EPS
+information and JPEG and Jpeg2000 images in PDF files, embedded MPF images
+in JPEG and MPO files, streaming metadata in AVCHD videos, and the resource
+fork of Mac OS files. Implies the B<-a> option. Use B<-g3> or B<-G3> to
+identify the originating document for extracted information. Embedded
+documents containing sub-documents are indicated with dashes in the family 3
+group name. (eg. C<Doc2-3> is the 3rd sub-document of the 2nd embedded
+document.) Note that this option may increase processing time substantially,
+especially for PDF files with many embedded images or videos with streaming
+metadata.
+
+When used with B<-ee>, the B<-p> option is evaluated for each embedded
+document as if it were a separate input file. This allows, for example,
+generation of GPS track logs from timed metadata in videos. See
+L<https://exiftool.org/geotag.html#Inverse> for examples.
+
+=item B<-ext>[+] I<EXT>, B<--ext> I<EXT> (B<-extension>)
+
+Process only files with (B<-ext>) or without (B<--ext>) a specified
+extension. There may be multiple B<-ext> and B<--ext> options. A plus sign
+may be added (ie. B<-ext+>) to add the specified extension to the normally
+processed files. EXT may begin with a leading '.', which is ignored. Case
+is not significant. C<"*"> may be used to process files with any extension
+(or none at all), as in the last three examples:
+
+ exiftool -ext JPG DIR # process only JPG files
+ exiftool --ext cr2 --ext dng DIR # supported files but CR2/DNG
+ exiftool -ext+ txt DIR # supported files plus TXT
+ exiftool -ext "*" DIR # process all files
+ exiftool -ext "*" --ext xml DIR # process all but XML files
+ exiftool -ext "*" --ext . DIR # all but those with no ext
+
+Using this option has two main advantages over specifying C<*.I<EXT>> on the
+command line: 1) It applies to files in subdirectories when combined with
+the B<-r> option. 2) The B<-ext> option is case-insensitive, which is
+useful when processing files on case-sensitive filesystems.
+
+Note that all files specified on the command line will be processed
+regardless of extension unless the B<-ext> option is used.
+
+=item B<-F>[I<OFFSET>] (B<-fixBase>)
+
+Fix the base for maker notes offsets. A common problem with some image
+editors is that offsets in the maker notes are not adjusted properly when
+the file is modified. This may cause the wrong values to be extracted for
+some maker note entries when reading the edited file. This option allows an
+integer I<OFFSET> to be specified for adjusting the maker notes base offset.
+If no I<OFFSET> is given, ExifTool takes its best guess at the correct base.
+Note that exiftool will automatically fix the offsets for images which store
+original offset information (eg. newer Canon models). Offsets are fixed
+permanently if B<-F> is used when writing EXIF to an image. eg)
+
+ exiftool -F -exif:resolutionunit=inches image.jpg
+
+=item B<-fast>[I<NUM>]
+
+Increase speed of extracting information. With B<-fast> (or B<-fast1>),
+ExifTool will not scan to the end of a JPEG image to check for an AFCP or
+PreviewImage trailer, or past the first comment in GIF images or the
+audio/video data in WAV/AVI files to search for additional metadata. These
+speed benefits are small when reading images directly from disk, but can be
+substantial if piping images through a network connection. For more
+substantial speed benefits, B<-fast2> also causes exiftool to avoid
+extracting any EXIF MakerNote information. B<-fast3> avoids extracting
+metadata from the file, and returns only pseudo System tags, but still reads
+the file header to obtain an educated guess at FileType. B<-fast4> doesn't
+even read the file header, and returns only System tags and a FileType based
+on the file extension. B<-fast5> also disables generation of the Composite
+tags (like B<-e>). Has no effect when writing.
+
+Note that a separate B<-fast> setting may be used for evaluation of a B<-if>
+condition, or when ordering files with the B<-fileOrder> option. See the
+B<-if> and B<-fileOrder> options for details.
+
+=item B<-fileOrder>[I<NUM>] [-]I<TAG>
+
+Set file processing order according to the sorted value of the specified
+I<TAG>. For example, to process files in order of date:
+
+ exiftool -fileOrder DateTimeOriginal DIR
+
+Additional B<-fileOrder> options may be added for secondary sort keys.
+Numbers are sorted numerically, and all other values are sorted
+alphabetically. Files missing the specified tag are sorted last. The sort
+order may be reversed by prefixing the tag name with a C<-> (eg.
+C<-fileOrder -createdate>). Print conversion of the sorted values is
+disabled with the B<-n> option, or a C<#> appended to the tag name. Other
+formatting options (eg. B<-d>) have no effect on the sorted values. Note
+that the B<-fileOrder> option can have a large performance impact since it
+involves an additional processing pass of each file, but this impact may be
+reduced by specifying a I<NUM> for the B<-fast> level used during the
+metadata-extraction phase. For example, B<-fileOrder4> may be used if
+I<TAG> is a pseudo System tag. If multiple B<-fileOrder> options are used,
+the extraction is done at the lowest B<-fast> level. Note that files are
+sorted across directory boundaries if multiple input directories are
+specified.
+
+=item B<-i> I<DIR> (B<-ignore>)
+
+Ignore specified directory name. I<DIR> may be either an individual folder
+name, or a full path. If a full path is specified, it must match the
+Directory tag exactly to be ignored. Use multiple B<-i> options to ignore
+more than one directory name. A special I<DIR> value of C<SYMLINKS> (case
+sensitive) may be specified to ignore symbolic links when the B<-r> option
+is used.
+
+=item B<-if>[I<NUM>] I<EXPR>
+
+Specify a condition to be evaluated before processing each I<FILE>. I<EXPR>
+is a Perl-like logic expression containing tag names prefixed by C<$>
+symbols. It is evaluated with the tags from each I<FILE> in turn, and the
+file is processed only if the expression returns true. Unlike Perl variable
+names, tag names are not case sensitive and may contain a hyphen. As well,
+tag names may have a leading group names separated by colons, and/or a
+trailing C<#> character to disable print conversion. The expression
+C<$GROUP:all> evaluates to 1 if any tag exists in the specified C<GROUP>, or
+0 otherwise (see note 2 below). When multiple B<-if> options are used, all
+conditions must be satisfied to process the file. Returns an exit status of
+2 if all files fail the condition. Below are a few examples:
+
+ # extract shutterspeed from all Canon images in a directory
+ exiftool -shutterspeed -if '$make eq "Canon"' dir
+
+ # add one hour to all images created on or after Apr. 2, 2006
+ exiftool -alldates+=1 -if '$CreateDate ge "2006:04:02"' dir
+
+ # set EXIF ISO value if possible, unless it is set already
+ exiftool '-exif:iso<iso' -if 'not $exif:iso' dir
+
+ # find images containing a specific keyword (case insensitive)
+ exiftool -if '$keywords =~ /harvey/i' -filename dir
+
+Adding I<NUM> to the B<-if> option causes a separate processing pass to be
+executed for evaluating I<EXPR> at a B<-fast> level given by I<NUM> (see the
+B<-fast> option documentation for details). Without I<NUM>, only one
+processing pass is done at the level specified by the B<-fast> option. For
+example, using B<-if5> is possible if I<EXPR> uses only pseudo System tags,
+and may significantly speed processing if enough files fail the condition.
+
+The expression has access to the current ExifTool object through C<$self>,
+and the following special functions are available to allow short-circuiting
+of the file processing. Both functions have a return value of 1. Case is
+significant for function names.
+
+ End() - end processing after this file
+ EndDir() - end processing of files in this directory (not
+ compatible with the B<-fileOrder> option)
+
+Notes:
+
+1) The B<-n> and B<-b> options also apply to tags used in I<EXPR>.
+
+2) Some binary data blocks are not extracted unless specified explicitly.
+These tags are not available for use in the B<-if> condition unless they are
+also specified on the command line. The alternative is to use the
+C<$GROUP:all> syntax. (eg. Use C<$exif:all> instead of C<$exif> in I<EXPR>
+to test for the existence of EXIF tags.)
+
+3) Tags in the string are interpolated the same way as with B<-p> before the
+expression is evaluated. In this interpolation, C<$/> is converted to a
+newline and C<$$> represents a single C<$> symbol (so Perl variables, if
+used, require a double C<$>).
+
+4) The condition may only test tags from the file being processed. To
+process one file based on tags from another, two steps are required. For
+example, to process XMP sidecar files in directory C<DIR> based on tags from
+the associated NEF:
+
+ exiftool -if EXPR -p '$directory/$filename' -ext nef DIR > nef.txt
+ exiftool -@ nef.txt -srcfile %d%f.xmp ...
+
+5) The B<-a> option has no effect on the evaluation of the expression, and
+the values of duplicate tags are accessible only by specifying a group name
+(such as a family 4 instance number, eg. C<$Copy1:TAG>, C<$Copy2:TAG>, etc).
+
+6) A special "OK" UserParam is available to test the success of the previous
+command when B<-execute> was used, and may be used like any other tag in the
+condition (ie. "$OK").
+
+=item B<-m> (B<-ignoreMinorErrors>)
+
+Ignore minor errors and warnings. This enables writing to files with minor
+errors and disables some validation checks which could result in minor
+warnings. Generally, minor errors/warnings indicate a problem which usually
+won't result in loss of metadata if ignored. However, there are exceptions,
+so ExifTool leaves it up to you to make the final decision. Minor errors
+and warnings are indicated by "[minor]" at the start of the message.
+Warnings which affect processing when ignored are indicated by "[Minor]"
+(with a capital "M"). Note that this causes missing values in
+B<-tagsFromFile>, B<-p> and B<-if> strings to be set to an empty string
+rather than an undefined value.
+
+=item B<-o> I<OUTFILE> or I<FMT> (B<-out>)
+
+Set the output file or directory name when writing information. Without
+this option, when any "real" tags are written the original file is renamed
+to C<FILE_original> and output is written to I<FILE>. When writing only
+FileName and/or Directory "pseudo" tags, B<-o> causes the file to be copied
+instead of moved, but directories specified for either of these tags take
+precedence over that specified by the B<-o> option.
+
+I<OUTFILE> may be C<-> to write to stdout. The output file name may also be
+specified using a I<FMT> string in which %d, %f and %e represent the
+directory, file name and extension of I<FILE>. Also, %c may be used to add
+a copy number. See the B<-w> option for I<FMT> string examples.
+
+The output file is taken to be a directory name if it already exists as a
+directory or if the name ends with '/'. Output directories are created if
+necessary. Existing files will not be overwritten. Combining the
+B<-overwrite_original> option with B<-o> causes the original source file to
+be erased after the output file is successfully written.
+
+A special feature of this option allows the creation of certain types of
+files from scratch, or with the metadata from another type of file. The
+following file types may be created using this technique:
+
+ XMP, EXIF, EXV, MIE, ICC/ICM, VRD, DR4
+
+The output file type is determined by the extension of I<OUTFILE> (specified
+as C<-.EXT> when writing to stdout). The output file is then created from a
+combination of information in I<FILE> (as if the B<-tagsFromFile> option was
+used), and tag values assigned on the command line. If no I<FILE> is
+specified, the output file may be created from scratch using only tags
+assigned on the command line.
+
+=item B<-overwrite_original>
+
+Overwrite the original I<FILE> (instead of preserving it by adding
+C<_original> to the file name) when writing information to an image.
+Caution: This option should only be used if you already have separate backup
+copies of your image files. The overwrite is implemented by renaming a
+temporary file to replace the original. This deletes the original file and
+replaces it with the edited version in a single operation. When combined
+with B<-o>, this option causes the original file to be deleted if the output
+file was successfully written (ie. the file is moved instead of copied).
+
+=item B<-overwrite_original_in_place>
+
+Similar to B<-overwrite_original> except that an extra step is added to
+allow the original file attributes to be preserved. For example, on a Mac
+this causes the original file creation date, type, creator, label color,
+icon, Finder tags, other extended attributes and hard links to the file to
+be preserved (but note that the Mac OS resource fork is always preserved
+unless specifically deleted with C<-rsrc:all=>). This is implemented by
+opening the original file in update mode and replacing its data with a copy
+of a temporary file before deleting the temporary. The extra step results
+in slower performance, so the B<-overwrite_original> option should be used
+instead unless necessary.
+
+Note that this option reverts to the behaviour of the B<-overwrite_original>
+option when also writing the FileName and/or Directory tags.
+
+=item B<-P> (B<-preserve>)
+
+Preserve the filesystem modification date/time (C<FileModifyDate>) of the
+original file when writing. Note that some filesystems store a creation
+date (ie. C<FileCreateDate> on Windows and Mac systems) which is not
+affected by this option. This creation date is preserved on Windows systems
+where Win32API::File and Win32::API are available regardless of this
+setting. For other systems, the B<-overwrite_original_in_place> option may
+be used if necessary to preserve the creation date. The B<-P> option is
+superseded by any value written to the FileModifyDate tag.
+
+=item B<-password> I<PASSWD>
+
+Specify password to allow processing of password-protected PDF documents.
+If a password is required but not given, a warning is issued and the
+document is not processed. This option is ignored if a password is not
+required.
+
+=item B<-progress>[:[I<TITLE>]]
+
+Show the progress when processing files. Without a colon, the B<-progress>
+option adds a progress count in brackets after the name of each processed
+file, giving the current file number and the total number of files to be
+processed. Implies the B<-v0> option, causing the names of processed files
+to also be printed when writing. When combined with the B<-if> option, the
+total count includes all files before the condition is applied, but files
+that fail the condition will not have their names printed.
+
+If followed by a colon (ie. B<-progress:>), the console window title is set
+according to the specified I<TITLE> string. If no I<TITLE> is given, a
+default I<TITLE> string of "ExifTool %p%%" is assumed. In the string, %f
+represents the file name, %p is the progress as a percent, %r is the
+progress as a ratio, %##b is a progress bar of width "##" (20 characters if
+"##" is omitted), and %% is a % character. May be combined with the normal
+B<-progress> option to also show the progress count in console messages.
+(Note: For this feature to function correctly on Mac/Linux, stderr must go
+to the console.)
+
+=item B<-q> (B<-quiet>)
+
+Quiet processing. One B<-q> suppresses normal informational messages, and a
+second B<-q> suppresses warnings as well. Error messages can not be
+suppressed, although minor errors may be downgraded to warnings with the
+B<-m> option, which may then be suppressed with C<-q -q>.
+
+=item B<-r>[.] (B<-recurse>)
+
+Recursively process files in subdirectories. Only meaningful if I<FILE> is
+a directory name. Subdirectories with names beginning with "." are not
+processed unless "." is added to the option name (ie. B<-r.> or
+B<-recurse.>). By default, exiftool will also follow symbolic links to
+directories if supported by the system, but this may be disabled with
+C<-i SYMLINKS> (see the B<-i> option for details). Combine this with
+B<-ext> options to control the types of files processed.
+
+=item B<-scanForXMP>
+
+Scan all files (even unsupported formats) for XMP information unless found
+already. When combined with the B<-fast> option, only unsupported file
+types are scanned. Warning: It can be time consuming to scan large files.
+
+=item B<-u> (B<-unknown>)
+
+Extract values of unknown tags. Add another B<-u> to also extract unknown
+information from binary data blocks. This option applies to tags with
+numerical tag ID's, and causes tag names like "Exif_0xc5d9" to be generated
+for unknown information. It has no effect on information types which have
+human-readable tag ID's (such as XMP), since unknown tags are extracted
+automatically from these formats.
+
+=item B<-U> (B<-unknown2>)
+
+Extract values of unknown tags as well as unknown information from some
+binary data blocks. This is the same as two B<-u> options.
+
+=item B<-wm> I<MODE> (B<-writeMode>)
+
+Set mode for writing/creating tags. I<MODE> is a string of one or more
+characters from the list below. The default write mode is C<wcg>.
+
+ w - Write existing tags
+ c - Create new tags
+ g - create new Groups as necessary
+
+For example, use C<-wm cg> to only create new tags (and avoid editing
+existing ones).
+
+The level of the group is the SubDirectory level in the metadata structure.
+For XMP or IPTC this is the full XMP/IPTC block (the family 0 group), but
+for EXIF this is the individual IFD (the family 1 group).
+
+=item B<-z> (B<-zip>)
+
+When reading, causes information to be extracted from .gz and .bz2
+compressed images (only one image per archive; requires gzip and bzip2 to be
+available). When writing, causes compressed information to be written if
+supported by the metadata format (eg. compressed textual metadata in PNG),
+disables the recommended padding in embedded XMP (saving 2424 bytes when
+writing XMP in a file), and writes XMP in shorthand format -- the equivalent
+of setting the API Compress=1 and Compact="NoPadding,Shorthand".

+=head3 Other options
+
+=over 5
+
+=item B<-@> I<ARGFILE>
+
+Read command-line arguments from the specified file. The file contains one
+argument per line (NOT one option per line -- some options require
+additional arguments, and all arguments must be placed on separate lines).
+Blank lines and lines beginning with C<#> are ignored (unless they start
+with C<#[CSTR]>, in which case the rest of the line is treated as a C
+string, allowing standard C escape sequences such as "\n" for a newline).
+White space at the start of a line is removed. Normal shell processing of
+arguments is not performed, which among other things means that arguments
+should not be quoted and spaces are treated as any other character.
+I<ARGFILE> may exist relative to either the current directory or the
+exiftool directory unless an absolute pathname is given.
+
+For example, the following I<ARGFILE> will set the value of Copyright to
+"Copyright YYYY, Phil Harvey", where "YYYY" is the year of CreateDate:
+
+ -d
+ %Y
+ -copyright<Copyright $createdate, Phil Harvey
+
+Arguments in I<ARGFILE> behave exactly the same as if they were entered at
+the location of the B<-@> option on the command line, with the exception
+that the B<-config> and B<-common_args> options may not be used in an
+I<ARGFILE>.
+
+=item B<-k> (B<-pause>)
+
+Pause with the message C<-- press any key --> or C<-- press RETURN -->
+(depending on your system) before terminating. This option is used to
+prevent the command window from closing when run as a Windows drag and drop
+application.
+
+=item B<-list>, B<-listw>, B<-listf>, B<-listr>, B<-listwf>,
+B<-listg>[I<NUM>], B<-listd>, B<-listx>
+
+Print a list of all valid tag names (B<-list>), all writable tag names
+(B<-listw>), all supported file extensions (B<-listf>), all recognized file
+extensions (B<-listr>), all writable file extensions (B<-listwf>), all tag
+groups [in a specified family] (B<-listg>[I<NUM>]), all deletable tag groups
+(B<-listd>), or an XML database of tag details including language
+translations (B<-listx>). The B<-list>, B<-listw> and B<-listx> options may
+be followed by an additional argument of the form C<-GROUP:All> to list only
+tags in a specific group, where C<GROUP> is one or more family 0-2 group
+names (excepting EXIF IFD groups) separated by colons. With B<-listg>,
+I<NUM> may be given to specify the group family, otherwise family 0 is
+assumed. The B<-l> option may be combined with B<-listf>, B<-listr> or
+B<-listwf> to add file descriptions to the list. The B<-lang> option may be
+combined with B<-listx> to output descriptions in a single language. Here
+are some examples:
+
+ -list # list all tag names
+ -list -EXIF:All # list all EXIF tags
+ -list -xmp:time:all # list all XMP tags relating to time
+ -listw -XMP-dc:All # list all writable XMP-dc tags
+ -listf # list all supported file extensions
+ -listr # list all recognized file extensions
+ -listwf # list all writable file extensions
+ -listg1 # list all groups in family 1
+ -listd # list all deletable groups
+ -listx -EXIF:All # list database of EXIF tags in XML format
+ -listx -XMP:All -s # list short XML database of XMP tags
+
+When combined with B<-listx>, the B<-s> option shortens the output by
+omitting the descriptions and values (as in the last example above), and
+B<-f> adds a 'flags' attribute if applicable. The flags are formatted as a
+comma-separated list of the following possible values: Avoid, Binary, List,
+Mandatory, Permanent, Protected, Unknown and Unsafe (see the L<Tag Name
+documentation|Image::ExifTool::TagNames>). For XMP List tags, the list type
+(Alt, Bag or Seq) is added to the flags, and flattened structure tags are
+indicated by a Flattened flag.
+
+Note that none of the B<-list> options require an input I<FILE>.
+
+=item B<-ver>
+
+Print exiftool version number. The B<-v> option may be added to print
+addition system information (see the README file of the full distribution
+for more details about optional libraries), or B<-v2> to also list the Perl
+include directories.

+=head3 Special features
+
+=over 5
+
+=item B<-geotag> I<TRKFILE>
+
+Geotag images from the specified GPS track log file. Using the B<-geotag>
+option is equivalent to writing a value to the C<Geotag> tag. The GPS
+position is interpolated from the track at a time specified by the value
+written to the C<Geotime> tag. If C<Geotime> is not specified, the value is
+copied from C<DateTimeOriginal#> (the C<#> is added to copy the unformatted
+value, avoiding potential conflicts with the B<-d> option). For example,
+the following two commands are equivalent:
+
+ exiftool -geotag trk.log image.jpg
+ exiftool -geotag trk.log "-Geotime<DateTimeOriginal#" image.jpg
+
+When the C<Geotime> value is converted to UTC, the local system timezone is
+assumed unless the date/time value contains a timezone. Writing C<Geotime>
+causes the following tags to be written (provided they can be calculated
+from the track log, and they are supported by the destination metadata
+format): GPSLatitude, GPSLatitudeRef, GPSLongitude, GPSLongitudeRef,
+GPSAltitude, GPSAltitudeRef, GPSDateStamp, GPSTimeStamp, GPSDateTime,
+GPSTrack, GPSTrackRef, GPSSpeed, GPSSpeedRef, GPSImgDirection,
+GPSImgDirectionRef, GPSPitch, GPSRoll, AmbientTemperature and
+CameraElevationAngle. By default, tags are created in EXIF, and updated in
+XMP only if they already exist. However, C<EXIF:Geotime> or C<XMP:Geotime>
+may be specified to write only EXIF or XMP tags respectively. Note that
+GPSPitch and GPSRoll are non-standard, and require user-defined tags in
+order to be written.
+
+The C<Geosync> tag may be used to specify a time correction which is applied
+to each C<Geotime> value for synchronization with GPS time. For example,
+the following command compensates for image times which are 1 minute and 20
+seconds behind GPS:
+
+ exiftool -geosync=+1:20 -geotag a.log DIR
+
+Advanced C<Geosync> features allow a linear time drift correction and
+synchronization from previously geotagged images. See "geotag.html" in the
+full ExifTool distribution for more information.
+
+Multiple B<-geotag> options may be used to concatenate GPS track log data.
+Also, a single B<-geotag> option may be used to load multiple track log
+files by using wildcards in the I<TRKFILE> name, but note that in this case
+I<TRKFILE> must be quoted on most systems (with the notable exception of
+Windows) to prevent filename expansion. For example:
+
+ exiftool -geotag "TRACKDIR/*.log" IMAGEDIR
+
+Currently supported track file formats are GPX, NMEA RMC/GGA/GLL, KML, IGC,
+Garmin XML and TCX, Magellan PMGNTRK, Honeywell PTNTHPR, Bramor gEO, Winplus
+Beacon TXT, and GPS/IMU CSV files. See L</GEOTAGGING EXAMPLES> for
+examples. Also see "geotag.html" in the full ExifTool distribution and the
+L<Image::ExifTool Options|Image::ExifTool/Options> for more details and for
+information about geotag configuration options.
+
+=item B<-globalTimeShift> I<SHIFT>
+
+Shift all formatted date/time values by the specified amount when reading.
+Does not apply to unformatted (B<-n>) output. I<SHIFT> takes the same form
+as the date/time shift when writing (see
+L<Image::ExifTool::Shift.pl|Image::ExifTool::Shift.pl> for details), with a
+negative shift being indicated with a minus sign (C<->) at the start of the
+I<SHIFT> string. For example:
+
+ # return all date/times, shifted back by 1 hour
+ exiftool -globalTimeShift -1 -time:all a.jpg
+
+ # set the file name from the shifted CreateDate (-1 day) for
+ # all images in a directory

+ -d %Y%m%d-%H%M%S.%%e dir
+
+=item B<-use> I<MODULE>
+
+Add features from specified plug-in I<MODULE>. Currently, the MWG module is
+the only plug-in module distributed with exiftool. This module adds
+read/write support for tags as recommended by the Metadata Working Group.
+As a convenience, C<-use MWG> is assumed if the C<MWG> group is specified
+for any tag on the command line. See the L<MWG Tags
+documentation|Image::ExifTool::TagNames/MWG Tags> for more details. Note

+
+=item B<-restore_original>
+
+=item B<-delete_original>[!]
+
+These utility options automate the maintenance of the C<_original> files
+created by exiftool. They have no effect on files without an C<_original>
+copy. The B<-restore_original> option restores the specified files from
+their original copies by renaming the C<_original> files to replace the
+edited versions. For example, the following command restores the originals
+of all JPG images in directory C<DIR>:
+
+ exiftool -restore_original -ext jpg DIR
+
+The B<-delete_original> option deletes the C<_original> copies of all files
+specified on the command line. Without a trailing C<!> this option prompts
+for confirmation before continuing. For example, the following command
+deletes C<a.jpg_original> if it exists, after asking "Are you sure?":
+
+ exiftool -delete_original a.jpg
+
+These options may not be used with other options to read or write tag values
+in the same command, but may be combined with options such B<-ext>, B<-if>,
+B<-r>, B<-q> and B<-v>.

+
+=head3 Advanced options
+
+Among other things, the advanced options allow complex processing to be
+performed from a single command without the need for additional scripting.
+This may be particularly useful for implementations such as Windows
+drag-and-drop applications. These options may also be used to improve
+performance in multi-pass processing by reducing the overhead required to
+load exiftool for each invocation.
+
+=over 5
+
+=item B<-api> I<OPT[[^]=[VAL]]>
+
+Set ExifTool API option. I<OPT> is an API option name. The option value is
+set to 1 if I<=VAL> is omitted. If I<VAL> is omitted, the option value is
+set to undef if C<=> is used, or an empty string with C<^=>. See
+L<Image::ExifTool Options|Image::ExifTool/Options> for a list of available
+API options. This overrides API options set via the config file.
+
+=item B<-common_args>
+
+Specifies that all arguments following this option are common to all
+executed commands when B<-execute> is used. This and the B<-config> option
+are the only options that may not be used inside a B<-@> I<ARGFILE>. Note
+that by definition this option and its arguments MUST come after all other
+options on the command line.
+
+=item B<-config> I<CFGFILE>
+
+Load specified configuration file instead of the default ".ExifTool_config".
+If used, this option must come before all other arguments on the command
+line and applies to all B<-execute>'d commands. The I<CFGFILE> must exist
+relative to the current working directory or the exiftool application
+directory unless an absolute path is specified. Loading of the default
+config file may be disabled by setting I<CFGFILE> to an empty string (ie.
+""). See L<https://exiftool.org/config.html> and
+config_files/example.config in the full ExifTool distribution for details
+about the configuration file syntax.
+
+=item B<-echo>[I<NUM>] I<TEXT>
+
+Echo I<TEXT> to stdout (B<-echo> or B<-echo1>) or stderr (B<-echo2>). Text
+is output as the command line is parsed, before the processing of any input
+files. I<NUM> may also be 3 or 4 to output text (to stdout or stderr
+respectively) after processing is complete. For B<-echo3> and B<-echo4>,
+"${status}" may be used in the I<TEXT> string to represent the numerical
+exit status of the command (see L</EXIT STATUS>).
+
+=item B<-efile>[I<NUM>][!] I<ERRFILE>
+
+Save the names of files giving errors (I<NUM> missing or 1), files that were
+unchanged (I<NUM> is 2), files that fail the B<-if> condition (I<NUM> is 4),
+or any combination thereof (by summing I<NUM>, eg. B<-efile3> is the same
+has having both B<-efile> and B<-efile2> options with the same I<ERRFILE>).
+By default, file names are appended to any existing I<ERRFILE>, but
+I<ERRFILE> is overwritten if an exclamation point is added to the option
+(eg. B<-efile!>). Saves the name of the file specified by the B<-srcfile>
+option if applicable.
+
+=item B<-execute>[I<NUM>]
+
+Execute command for all arguments up to this point on the command line (plus
+any arguments specified by B<-common_args>). The result is as if the
+commands were executed as separate command lines (with the exception of the
+B<-config> and B<-use> options which remain in effect for subsequent
+commands). Allows multiple commands to be executed from a single command
+line. I<NUM> is an optional number that is echoed in the "{ready}" message
+when using the B<-stay_open> feature. If a I<NUM> is specified, the B<-q>
+option no longer suppresses the output "{readyNUM}" message.
+
+=item B<-srcfile> I<FMT>
+
+Specify a different source file to be processed based on the name of the
+original I<FILE>. This may be useful in some special situations for
+processing related preview images or sidecar files. See the B<-w> option
+for a description of the I<FMT> syntax. Note that file name I<FMT> strings
+for all options are based on the original I<FILE> specified from the command
+line, not the name of the source file specified by B<-srcfile>.
+
+For example, to copy metadata from NEF files to the corresponding JPG
+previews in a directory where other JPG images may exist:
+
+ exiftool -ext nef -tagsfromfile @ -srcfile %d%f.jpg dir
+
+If more than one B<-srcfile> option is specified, the files are tested in
+order and the first existing source file is processed. If none of the
+source files already exist, then exiftool uses the first B<-srcfile>
+specified.
+
+A I<FMT> of C<@> may be used to represent the original I<FILE>, which may be
+useful when specifying multiple B<-srcfile> options (eg. to fall back to
+processing the original I<FILE> if no sidecar exists).
+
+When this option is used, two special UserParam tags (OriginalFileName and
+OriginalDirectory) are generated to allow access to the original I<FILE>
+name and directory.
+
+=item B<-stay_open> I<FLAG>
+
+If I<FLAG> is C<1> or C<True>, causes exiftool keep reading from the B<-@>
+I<ARGFILE> even after reaching the end of file. This feature allows calling
+applications to pre-load exiftool, thus avoiding the overhead of loading
+exiftool for each command. The procedure is as follows:
+
+1) Execute C<exiftool -stay_open True -@ I<ARGFILE>>, where I<ARGFILE> is the
+name of an existing (possibly empty) argument file or C<-> to pipe arguments
+from the standard input.
+
+2) Write exiftool command-line arguments to I<ARGFILE>, one argument per
+line (see the B<-@> option for details).
+
+3) Write C<-execute\n> to I<ARGFILE>, where C<\n> represents a newline
+sequence. (Note: You may need to flush your write buffers here if using
+buffered output.) ExifTool will then execute the command with the arguments
+received up to this point, send a "{ready}" message to stdout when done
+(unless the B<-q> or B<-T> option is used), and continue trying to read
+arguments for the next command from I<ARGFILE>. To aid in command/response
+synchronization, any number appended to the C<-execute> option is echoed in
+the "{ready}" message. For example, C<-execute613> results in "{ready613}".
+When this number is added, B<-q> no longer suppresses the "{ready}" message.
+(Also, see the B<-echo3> and B<-echo4> options for additional ways to pass
+signals back to your application.)
+
+4) Repeat steps 2 and 3 for each command.
+
+5) Write C<-stay_open\nFalse\n> to I<ARGFILE> when done. This will cause
+exiftool to process any remaining command-line arguments then exit normally.
+
+The input I<ARGFILE> may be changed at any time before step 5 above by
+writing the following lines to the currently open I<ARGFILE>:
+
+ -stay_open
+ True
+ -@
+ NEWARGFILE
+
+This causes I<ARGFILE> to be closed, and I<NEWARGFILE> to be kept open.
+(Without the B<-stay_open> here, exiftool would have returned to reading
+arguments from I<ARGFILE> after reaching the end of I<NEWARGFILE>.)
+
+Note: When writing arguments to a disk file there is a delay of up to 0.01
+seconds after writing C<-execute\n> before exiftool starts processing the
+command. This delay may be avoided by sending a CONT signal to the exiftool
+process immediately after writing C<-execute\n>. (There is no associated
+delay when writing arguments via a pipe with C<-@ ->, so the signal is not
+necessary when using this technique.)
+
+=item B<-userParam> I<PARAM[[^]=[VAL]]>
+
+Set user parameter. I<PARAM> is an arbitrary user parameter name. This is
+an interface to the API UserParam option (see the
+L<Image::ExifTool Options|Image::ExifTool/Options> documentation), and
+provides a method to access user-defined parameters in arguments to the
+B<-if> and B<-p> options as if they were any other tag. Appending a hash
+tag (C<#>) to I<PARAM> also causes the parameter to be extracted as a normal
+tag (in the UserParam group). Similar to the B<-api> option, the parameter
+value is set to 1 if I<=VAL> is omitted, undef if just I<VAL> is omitted
+with C<=>, or an empty string if I<VAL> is omitted with C<^=>.
+
+ exiftool -p '$test from $filename' -userparam test=Hello FILE
+
+=back
+
+=head3 Advanced formatting feature
+
+An advanced formatting feature allows modification of the value of any tag
+interpolated within a B<-if> or B<-p> option argument, or a B<-tagsFromFile>
+redirection string. Tag names within these strings are prefixed by a C<$>
+symbol, and an arbitrary Perl expression may be applied to the tag value by
+placing braces around the tag name and inserting the expression after the
+name, separated by a semicolon (ie. C<${TAG;EXPR}>). The expression acts on
+the value of the tag through the default input variable (C<$_>), and has
+access to the full ExifTool API through the current ExifTool object
+(C<$self>) and the tag key (C<$tag>). It may contain any valid Perl code,
+including translation (C<tr///>) and substitution (C<s///>) operations, but
+note that braces within the expression must be balanced. The example below
+prints the camera Make with spaces translated to underlines, and multiple
+consecutive underlines replaced by a single underline:
+
+ exiftool -p '${make;tr/ /_/;s/__+/_/g}' image.jpg
+
+An C<@> may be added after the tag name to make the expression act on
+individual list items for list-type tags, simplifying list processing. Set
+C<$_> to undef to remove an item from the list. As an example, the
+following command returns all subjects not containing the string "xxx":
+
+ exiftool -p '${subject@;$_=undef if /xxx/}' image.jpg
+
+A default expression of C<tr(/\\?*:|"E<lt>E<gt>\0)()d> is assumed if the
+expression is empty (ie. C<${TAG;}>). This removes the characters / \ ? * :
+| E<lt> E<gt> and null from the printed value. (These characters are
+illegal in Windows file names, so this feature is useful if tag values are
+used in file names.)
+
+=head4 Helper functions
+
+C<DateFmt>
+
+Simplifies reformatting of individual date/time values. This function acts
+on a standard EXIF-formatted date/time value in C<$_> and formats it
+according to the specified format string (see the B<-d> option). To avoid
+trying to reformat an already-formatted date/time value, a C<#> must be
+added to the tag name (as in the example below) if the B<-d> option is also
+used. For example:
+
+ exiftool -p '${createdate#;DateFmt("%Y-%m-%d_%H%M%S")}' a.jpg
+
+C<ShiftTime>
+
+Shifts EXIF-formatted date/time string by a specified amount. Start with a
+leading minus sign to shift backwards in time. See
+L<Image::ExifTool::Shift.pl|Image::ExifTool::Shift.pl> for details about
+shift syntax. For example, to shift a date/time value back by one year:
+
+ exiftool -p '${createdate;ShiftTime("-1:0:0 0")}' a.jpg
+
+C<NoDups>
+
+Removes duplicate items from a list with a separator specified by the
+B<-sep> option. This function is most useful when copying list-type tags.
+For example, the following command may be used to remove duplicate Keywords:
+
+ exiftool -sep '##' '-keywords<${keywords;NoDups}' a.jpg
+
+The B<-sep> option is necessary to split the string back into individual
+list items when writing to a list-type tag.
+
+An optional flag argument may be set to 1 to cause C<NoDups> to return undef
+if no duplicates existed, thus preventing the file from being rewritten
+unnecessarily:
+
+ exiftool -sep '##' '-keywords<${keywords;NoDups(1)}' a.jpg
+
+Note that function names are case sensitive.
+
+=head1 WINDOWS UNICODE FILE NAMES
+
+In Windows, command-line arguments are specified using the current code page
+and are recoded automatically to the system code page. This recoding is not
+done for arguments in ExifTool arg files, so by default filenames in arg
+files use the system code page. Unfortunately, these code pages are not
+complete character sets, so not all file names may be represented.
+
+ExifTool 9.79 and later allow the file name encoding to be specified with
+C<-charset filename=CHARSET>, where C<CHARSET> is the name of a valid
+ExifTool character set, preferably C<UTF8> (see the B<-charset> option for a
+complete list). Setting this triggers the use of Windows wide-character i/o
+routines, thus providing support for most Unicode file names (see note 4).
+But note that it is not trivial to pass properly encoded file names on the
+Windows command line (see L<https://exiftool.org/faq.html#Q18> for details),
+so placing them in a UTF-8 encoded B<-@> argfile and using C<-charset
+filename=utf8> is recommended if possible.
+
+A warning is issued if a specified filename contains special characters and
+the filename character set was not provided. However, the warning may be
+disabled by setting C<-charset filename="">, and ExifTool may still function
+correctly if the system code page matches the character set used for the
+file names.
+
+When a directory name is provided, the file name encoding need not be
+specified (unless the directory name contains special characters), and
+ExifTool will automatically use wide-character routines to scan the
+directory.
+
+The filename character set applies to the I<FILE> arguments as well as
+filename arguments of B<-@>, B<-geotag>, B<-o>, B<-p>, B<-srcfile>,
+B<-tagsFromFile>, B<-csv>=, B<-j>= and B<->I<TAG>E<lt>=. However, it does
+not apply to the B<-config> filename, which always uses the system character
+set. The C<-charset filename=> option must come before the B<-@> option to
+be effective, but the order doesn't matter with respect to other options.
+
+Notes:
+
+1) FileName and Directory tag values still use the same encoding as other
+tag values, and are converted to/from the filename character set when
+writing/reading if specified.
+
+2) Unicode support is not yet implemented for other Windows-based systems
+like Cygwin.
+
+3) See L</WRITING READ-ONLY FILES> below for a note about editing read-only
+files with Unicode names.
+
+4) Unicode file names with surrogate pairs (code points over U+FFFF) still
+cause problems.
+
+=head1 WRITING READ-ONLY FILES
+
+In general, ExifTool may be used to write metadata to read-only files
+provided that the user has write permission in the directory. However,
+there are three cases where file write permission is also required:
+
+1) When using the B<-overwrite_original_in_place> option.
+
+2) When writing only pseudo System tags (eg. FileModifyDate).
+
+3) On Windows if the file has Unicode characters in its name, and a) the
+B<-overwrite_original> option is used, or b) the C<_original> backup already
+exists.
+
+Hidden files in Windows behave as read-only files when attempting to write
+any real tags to the file -- an error is generated when using the
+B<-overwrite_original_in_place>, otherwise writing should be successful and
+the hidden attribute will be removed. But the B<-if> option may be used to
+avoid processing hidden files (provided Win32API::File is available):
+
+ exiftool -if "$fileattributes !~ /Hidden/" ...
+
+=head1 READING EXAMPLES
+
+B<Note>: Beware when cutting and pasting these examples into your terminal!
+Some characters such as single and double quotes and hyphens may have been
+changed into similar-looking yet functionally-different characters by the
+text formatter used to display this documentation. Also note that Windows
+users must use double quotes instead of single quotes as below around
+arguments containing special characters.

+Copy all meta information from C<a.jpg> to C<b.jpg>, deleting all XMP
+information and the thumbnail image from the destination.
+
+=item exiftool -TagsFromFile src.jpg -title -author=Phil dst.jpg
+
+Copy title from one image to another and set a new author name.
+
+=item exiftool -TagsFromFile a.jpg -ISO -TagsFromFile b.jpg -comment
+dst.jpg
+
+Copy ISO from one image and Comment from another image to a destination
+image.
+
+=item exiftool -tagsfromfile src.jpg -exif:all --subifd:all dst.jpg
+
+Copy only the EXIF information from one image to another, excluding SubIFD
+tags.
+
+=item exiftool '-FileModifyDateE<lt>DateTimeOriginal' dir
+
+Use the original date from the meta information to set the same file's
+filesystem modification date for all images in a directory. (Note that
+C<-TagsFromFile @> is assumed if no other B<-TagsFromFile> is specified when
+redirecting information as in this example.)
+
+=item exiftool -TagsFromFile src.jpg '-xmp:allE<lt>all' dst.jpg
+
+Copy all possible information from C<src.jpg> and write in XMP format to
+C<dst.jpg>.
+
+=item exiftool '-Description<${FileName;s/\.[^.]*$//}' dir
+
+Set the image Description from the file name after removing the extension.
+This example uses the L</Advanced formatting feature> to perform a
+substitution operation to remove the last dot and subsequent characters from
+the file name.
+
+=item exiftool -@ iptc2xmp.args -iptc:all= a.jpg
+
+Translate IPTC information to XMP with appropriate tag name conversions, and
+delete the original IPTC information from an image. This example uses
+iptc2xmp.args, which is a file included with the ExifTool distribution that
+contains the required arguments to convert IPTC information to XMP format.
+Also included with the distribution are xmp2iptc.args (which performs the
+inverse conversion) and a few more .args files for other conversions between
+EXIF, IPTC and XMP.
+
+=item exiftool -tagsfromfile %d%f.CR2 -r -ext JPG dir
+
+Recursively rewrite all C<JPG> images in C<dir> with information copied from
+the corresponding C<CR2> images in the same directories.
+
+=item exiftool '-keywords+E<lt>make' image.jpg
+
+Add camera make to list of keywords.
+
+=item exiftool '-commentE<lt>ISO=$exif:iso Exposure=${shutterspeed}' dir
+
+Set the Comment tag of all images in C<dir> from the values of the EXIF:ISO
+and ShutterSpeed tags. The resulting comment will be in the form "ISO=100
+Exposure=1/60".
+
+=item exiftool -TagsFromFile src.jpg -icc_profile dst.jpg
+
+Copy ICC_Profile from one image to another.
+
+=item exiftool -TagsFromFile src.jpg -all:all dst.mie
+
+Copy all meta information in its original form from a JPEG image to a MIE
+file. The MIE file will be created if it doesn't exist. This technique can
+be used to store the metadata of an image so it can be inserted back into
+the image (with the inverse command) later in a workflow.
+
+=item exiftool -o dst.mie -all:all src.jpg
+
+This command performs exactly the same task as the command above, except
+that the B<-o> option will not write to an output file that already exists.
+
+=item exiftool -b -jpgfromraw -w %d%f_%ue.jpg -execute -b -previewimage -w
+%d%f_%ue.jpg -execute -tagsfromfile @ -srcfile %d%f_%ue.jpg
+-overwrite_original -common_args --ext jpg DIR
+
+[Advanced] Extract JpgFromRaw or PreviewImage from all but JPG files in DIR,
+saving them with file names like C<image_EXT.jpg>, then add all meta
+information from the original files to the extracted images. Here, the
+command line is broken into three sections (separated by B<-execute>
+options), and each is executed as if it were a separate command. The
+B<-common_args> option causes the C<--ext jpg DIR> arguments to be applied
+to all three commands, and the B<-srcfile> option allows the extracted JPG
+image to be the source file for the third command (whereas the RAW files are
+the source files for the other two commands).
+
+=back
+
+=head1 RENAMING EXAMPLES
+
+By writing the C<FileName> and C<Directory> tags, files are renamed and/or
+moved to new directories. This can be particularly useful and powerful for
+organizing files by date when combined with the B<-d> option. New
+directories are created as necessary, but existing files will not be
+overwritten. The format codes %d, %f and %e may be used in the new file
+name to represent the directory, name and extension of the original file,
+and %c may be used to add a copy number if the file already exists (see the
+B<-w> option for details). Note that if used within a date format string,
+an extra '%' must be added to pass these codes through the date/time parser.
+(And further note that in a Windows batch file, all '%' characters must also
+be escaped, so in this extreme case '%%%%f' is necessary to pass a simple
+'%f' through the two levels of parsing.) See
+L<https://exiftool.org/filename.html> for additional documentation and
+examples.
+
+=over 5
+
+=item exiftool -filename=new.jpg dir/old.jpg
+
+Rename C<old.jpg> to C<new.jpg> in directory C<dir>.
+
+=item exiftool -directory=%e dir
+
+Move all files from directory C<dir> into directories named by the original
+file extensions.
+
+=item exiftool '-Directory<DateTimeOriginal' -d %Y/%m/%d dir
+
+Move all files in C<dir> into a directory hierarchy based on year, month and
+day of C<DateTimeOriginal>. eg) This command would move the file
+C<dir/image.jpg> with a C<DateTimeOriginal> of C<2005:10:12 16:05:56> to
+C<2005/10/12/image.jpg>.
+
+=item exiftool -o . '-Directory<DateTimeOriginal' -d %Y/%m/%d dir
+
+Same effect as above except files are copied instead of moved.
+
+=item exiftool '-filename<%f_${model;}.%e' dir
+
+Rename all files in C<dir> by adding the camera model name to the file name.
+The semicolon after the tag name inside the braces causes characters which
+are invalid in Windows file names to be deleted from the tag value (see the
+L</Advanced formatting feature> for an explanation).
+
+=item exiftool '-FileName<CreateDate' -d %Y%m%d_%H%M%S%%-c.%%e dir
+
+Rename all images in C<dir> according to the C<CreateDate> date and time,
+adding a copy number with leading '-' if the file already exists (C<%-c>),
+and preserving the original file extension (C<%e>). Note the extra '%'
+necessary to escape the filename codes (C<%c> and C<%e>) in the date format
+string.
+
+=item exiftool -r '-FileName<CreateDate' -d %Y-%m-%d/%H%M_%%f.%%e dir
+
+Both the directory and the filename may be changed together via the
+C<FileName> tag if the new C<FileName> contains a '/'. The example above
+recursively renames all images in a directory by adding a C<CreateDate>
+timestamp to the start of the filename, then moves them into new directories
+named by date.
+
+=item exiftool '-FileName<${CreateDate}_$filenumber.jpg' -d %Y%m%d -ext jpg .
+
+Set the filename of all JPG images in the current directory from the
+CreateDate and FileNumber tags, in the form "20060507_118-1861.jpg".
+
+=back
+
+=head1 GEOTAGGING EXAMPLES
+
+ExifTool implements geotagging via 3 special tags: Geotag (which for
+convenience is also implemented as an exiftool option), Geosync and Geotime.
+The examples below highlight some geotagging features. See
+L<https://exiftool.org/geotag.html> for additional documentation.
+
+=over 5
+
+=item exiftool -geotag track.log a.jpg
+
+Geotag an image (C<a.jpg>) from position information in a GPS track log
+(C<track.log>). Since the C<Geotime> tag is not specified, the value of
+DateTimeOriginal is used for geotagging. Local system time is assumed
+unless DateTimeOriginal contains a timezone.
+
+=item exiftool -geotag t.log -geotime='2009:04:02 13:41:12-05:00' a.jpg
+
+Geotag an image with the GPS position for a specific time.
+
+=item exiftool -geotag log.gpx '-xmp:geotimeE<lt>createdate' dir
+
+Geotag all images in directory C<dir> with XMP tags instead of EXIF tags,
+based on the image CreateDate.
+
+=item exiftool -geotag a.log -geosync=-20 dir
+
+Geotag images in directory C<dir>, accounting for image timestamps which
+were 20 seconds ahead of GPS.
+
+=item exiftool -geotag a.log -geosync=1.jpg -geosync=2.jpg dir
+
+Geotag images using time synchronization from two previously geotagged images
+(1.jpg and 2.jpg), synchronizing the image and GPS times using a linear time
+drift correction.
+
+=item exiftool -geotag a.log '-geotimeE<lt>${createdate}+01:00' dir
+
+Geotag images in C<dir> using CreateDate with the specified timezone. If
+CreateDate already contained a timezone, then the timezone specified on the
+command line is ignored.
+
+=item exiftool -geotag= a.jpg
+
+Delete GPS tags which may have been added by the geotag feature. Note that
+this does not remove all GPS tags -- to do this instead use C<-gps:all=>.
+
+=item exiftool -xmp:geotag= a.jpg
+
+Delete XMP GPS tags which were added by the geotag feature.
+
+=item exiftool -xmp:geotag=track.log a.jpg
+
+Geotag an image with XMP tags, using the time from DateTimeOriginal.
+
+=item exiftool -geotag a.log -geotag b.log -r dir
+
+Combine multiple track logs and geotag an entire directory tree of images.
+
+=item exiftool -geotag 'tracks/*.log' -r dir
+
+Read all track logs from the C<tracks> directory.
+
+=item exiftool -p gpx.fmt -d %Y-%m-%dT%H:%M:%SZ dir > out.gpx
+
+Generate a GPX track log from all images in directory C<dir>. This example
+uses the C<gpx.fmt> file included in the full ExifTool distribution package
+and assumes that the images in C<dir> have all been previously geotagged.
+
+=back
+
+=head1 PIPING EXAMPLES
+
+=over 5
+
+=item cat a.jpg | exiftool -
+
+Extract information from stdin.
+
+=item exiftool image.jpg -thumbnailimage -b | exiftool -
+
+Extract information from an embedded thumbnail image.
+
+=item cat a.jpg | exiftool -iptc:keywords+=fantastic - > b.jpg
+
+Add an IPTC keyword in a pipeline, saving output to a new file.
+
+=item curl -s http://a.domain.com/bigfile.jpg | exiftool -fast -
+
+Extract information from an image over the internet using the cURL utility.
+The B<-fast> option prevents exiftool from scanning for trailer information,
+so only the meta information header is transferred.
+
+=item exiftool a.jpg -thumbnailimage -b | exiftool -comment=wow - |
+exiftool a.jpg -thumbnailimage'<=-'
+
+Add a comment to an embedded thumbnail image. (Why anyone would want to do
+this I don't know, but I've included this as an example to illustrate the
+flexibility of ExifTool.)
+
+=back
+
+=head1 EXIT STATUS
+
+The exiftool application exits with a status of 0 on success, or 1 if an
+error occurred, or 2 if all files failed the B<-if> condition (for any of
+the commands if B<-execute> was used).

+# wayar-dwl.sh - display dwl tags, layout, and active title
+# Based heavily upon this script by user "novakane" (Hugo Machet) used to do the same for yambar
+# https://codeberg.org/novakane/yambar/src/branch/master/examples/scripts/dwl-tags.sh
+#
+# USAGE: waybar-dwl.sh MONITOR COMPONENT
+# "COMPONENT" is an integer representing a dwl tag OR "layout" OR "title"
+#
+# REQUIREMENTS:
+# - inotifywait ( 'inotify-tools' on arch )
+# - Launch dwl with `dwl > ~.cache/dwltags` or change $fname
+#
+# Now the fun part
+#
+### Example ~/.config/waybar/config

+# // For multi-monitor setups, see https://github.com/Alexays/Waybar/wiki/Configuration
