Play files in shuffle mode with bash and mpg123.

Why bother using big-as-hell stuff like mplayer? This will play all your music files contained in */* (in my case author/song.format) with bash and mplayer showing a nice output.

Know a better way?

If you can do better, submit your command here.

What others think

Wow, I didn't know that MPlayer can do something like that! Thank you!

By the way, on my system (Debian Lenny, MPlayer dev-SVN-r26940) PageDown don't switch back to previous song ? it just rewinds current one to the beginning.

To include files in subdirs too you can do: mplayer -shuffle -playlist

Pressing < to go to the previous track only seems to work if you're not using shuffle.

I meant: mplayer -shuffle -playlist

Comment by rkulla 327 weeks and 1 day ago

Hmm it's not interpreting my text right. I wish this site would let you delete comments. I'll try again: mplayer -shuffle -playlist <(find "$PWD")

Comment by rkulla 327 weeks and 1 day ago

for the -playlist switch, you have to make a file that contains the songs.

Either copy+paste the titles or type `ls Song_na* > myplaylist.pl`

or whatever you want your playlist file to be.

Submitted an alternative =)

Quite longer and uglier, but just mpg123 and bash, a nice, clean output and much less memory usage.
