+#!/bin/sh

+# - Syncs mail for all accounts, or a single account given as an argument.
+# - Displays a notification showing the number of new mails.
+# - Displays a notification for each new mail with its subject displayed.
+# - Runs notmuch to index new mail.
+# - This script can be set up as a cron job for automated mail syncing.
+
+# There are many arbitrary and ugly features in this script because it is
+# inherently difficult to pass environmental variables to cronjobs and other
+# issues. It also should at least be compatible with Linux (and maybe BSD) with
+# Xorg and MacOS as well.
+
+# Run only if user logged in (prevent cron errors)
+pgrep -u "${USER:=$LOGNAME}" >/dev/null || { echo "$USER not logged in; sync will not run."; exit ;}
+# Run only if not already running in other instance
+pgrep mbsync >/dev/null && { echo "mbsync is already running."; exit ;}
+
+# First, we have to get the right variables for the mbsync file, the pass
+# archive, notmuch and the GPG home.  This is done by searching common profile
+# files for variable assignments. This is ugly, but there are few options that
+# will work on the maximum number of machines.
