There have been plenty of times that I have had to search and search the output of "ps aux" to try and find a process that is locking a certain device. More often then not, it had to do with my sound device (/dev/dsp), so, I would issue the command "ps aux" and then manually look at the list of processes to see which ones, from memory, would lock up sound.

Finally a discovered a useful little command to acheive this exact same thing:

QUOTE
$ fuser /dev/dsp
/dev/dsp:  18535 18536 18537 18540 18541 18542


What this program does is that it gives you a list of processes that is currently using a certain device, in this case /dev/dsp .

So, to find out what the program is, just send the output of ps aux to grep:

QUOTE
$ ps aux | grep 18535
duende  18535  0.2  2.3 51644 12296 ?      S    14:45  0:00 xmms


To immediatly kill the process using the device, pass the -k parameter (fuser -k /dev/dsp).

Check out the fuser manpage to learn more.
