   1: #!/usr/bin/perl 
   2: # Plays a random file from $dir using $player.  
   3: # I still have not figured a good way to quit other than killing
   4: # the perl program and then the player, anybody have some good ideas?
   5: # UPDATE: now properly replaces escape characters (old version replaced with space)
   6: use strict;
   7: my $dir = "/dosc/Music/";
   8: my $player ="mpg123";

  12: closedir (DIR);
  13: foreach (@music) {
  14:     s/([\s|&|\\|\||(|)|'|_])/\\$1/g; # Add escape characters
  15: }
  16: srand();

    When I'm writing a daemon will drop a file ususally based on the PID $$ and then inside the loop test for the existence of the file and exit if the file is deleted:

    open PID,">$$" or die $@;
    close PID;

    while (-e $$) {
    do_good();
    }
