mpg - a bash script for cli control of mpg321

Written by jt - jt AT homis DOT org

I wanted a simple command-based interface for controlling mpg321 (play, pause, stop). This could be used with keyboard mappings, or from a desktop menu (e.g. the root menu in Openbox) to control music playback.

It is currently limited to playing a single song at a time (no queue/wildcard support in the filespec). The script doesn't use the else keyword because my bash version doesn't seem to support it.

Todo:
- Add switch for suppression of messages / mpg321 output
- Add wildcard/queue support?

The mpg source can be downloaded here {removed because it's currently broken and in need of fixing}; usage is explained below. Feel free to find/fix bugs, and to suggest/submit modifications.

Note that this relies on mpg321, which must be in your $PATH.

Usage: mpg [OPTION] [FILESPEC]
mpg is a bash script to ease cli control of mpg321 playback.

  p, --play FILESPEC       start a new mpg321 process, playing FILESPEC

  a, --pause,              pause (interrupt) playback; sends STOP signal to
  i, --interrupt            mpg321 process, putting it to sleep

  u, --unpause,            unpause (resume) playback; sends CONT signal to
  r, --resume               mpg321 process, waking it up

  s, --stop,               stop (quit) playback; sends INT signal to
  q, --quit                 mpg321 process, exiting it cleanly
