I have installed play :
sudo apt-get install sox libsox-fmt-mp3
I can now play my audio files like this :
play Desktop/SONGS/01\ -\ Oh\ Baby\ Girl.mp3
Since I'm learning shell, I wish I could do something like this :
(sleep 10 ; play Desktop/SONGS/01\ -\ Oh\ Baby\ Girl.mp3 ) &
After 10 sec's, I can see the screen as :
File Size: 7.38M Bit Rate: 260k
Encoding: MPEG audio Info: 2012
Channels: 2 @ 16-bit Track: 01/09
Samplerate: 44100Hz Album: Maalai Pozhudhin Mayakathilaey :::tunesinn.blogspot.com:::
Replaygain: off Artist: Hemachandra, Achu
Duration: 00:03:46.98 Title: Oh Baby Girl
But the song is not playing. But if I do this (without &) :
(sleep 10 ; play Desktop/SONGS/01\ -\ Oh\ Baby\ Girl.mp3 )
Is working as expected. But I couldn't able to use my terminal in meanwhile.
How could I resolve my problem, with using &?
Backgrounding play with & fails because play wants to output its status, e.g.
In:12.7% 00:00:27.31 [00:03:07.52] Out:1.20M [!=====|=====!] Hd:0.0 Clip:0
but cannot if backgrounded. So it keeps waiting until aborted.
To solve this, simply run play with the -q (quiet) switch. This will successfully background it and play will terminate when the song ends.
(sleep 10 ; play -q Desktop/SONGS/01\ -\ Oh\ Baby\ Girl.mp3 ) &
You can stop it by either typing
killall play(if no other play instances are running), or bykill $!(if you haven't backgrounded other processes in the same terminal after starting play -- $! gives you the PID of the last backgrounded process)
