mpd

How to continuously poll mpd for currently played song and write result to a file?

The only thing i need to extract from mpd is the currently played song/track. I have to ensure this always is up to date in the output file.

Solution

  • If you install mpc then you can do the following:

    mpc idle player # block until the player changes songs
mpc current     # outputs "Artist Name - Song Name" onto stdout

    Do those in a loop, and output the result of current into a file, and you're done!

    #!/bin/sh
while true
do
  mpc current > current_song.txt
  mpc idle player
done

    The full list of what you can idle for is on the MPD command reference:
