fuser and lsof Re: [olug] MPLAYER Blue screen.

[Brian Wiese]

May also want to try: fuser - identify processes using files or sockets

e.g.

bw at freedom:~ $ fuser /dev/stdin
/dev/stdin:          17190 17254
bw at freedom:~ $ ps 17190
  PID TTY      STAT   TIME COMMAND
17190 pts/6    Ss     0:00 bash
