Presently, it supports: + +- Increasing volume +- Decreasing volume +- Toggling the interface mute +- Toggling the microphone mute\* + +in both pulseaudio and ALSA\*. Once I get OpenBSD and FreeBSD up and running, I will add those sound options too. + +It depends on: + +- pamixer (pulseaudio) +- amixer (alsa) +- pgrep (with the -x command, standard in BSD and \*/Linux systems) + +#### But *why* though? + +I made volsv so that I could use it with keybindings to control the volume, regardless of whether or not I was running pulseaudio, since I dislike pulseaudio and tend to avoid it when possible. This means I can have a consistent keybinding, whether or not I'm using it. Additionally, this would give me less keybindings to have to port to OpenBSD, which I occasionally install from time to time, although I haven't booted into it since I started writing this script. Additionally, it has provided a fun learning experience as I learn to write scripts. + + + +\*Volsv does not yet support muting the microphone in ALSA. @@ -0,0 +1,38 @@ +#!/bin/sh +# print error message +printerror () { + echo "$1 is not a recognized command or flag" +} +# if pulseaudio +pulsesv () { + case "$1" in + "up" | "-i") pamixer -i 5 ;; + "down" | "-d") pamixer -d 5 ;; + "toggle" | "-t") pamixer -t ;; + "mic" | "-m") pamixer --source 1 -t ;; + "getm" | "-g") ;; + *) printerror "$1" ;; + esac +} +# if alsa +alsasv () { + case "$1" in + "up" | "-i") amixer sset Master 5%+ ;; + "down" | "-d") amixer sset Master 5%- ;; + "toggle" | "-t") amixer sset Master toggle ;; + "getm" | "-g") ;; + *) printerror "$1" ;; + esac +} +#Search input for +echo "$@" | grep -q ' *-h *' && echo \ +"Volsv is Free software.
