Of course if you are on Linux you could do:
Hi -
Yes, I agree ps -aux.
To do it from perl, use bacticks:
#!c:\perl\bin\perl -w
use strict;
my @processes = `ps -aux`;
print "$_" for @processes;
@processes has _everything_ about your currently
running processes (depenging on your permission
level).

the system command does not return pids. it only returns error status
numbers(constants).
check perldoc -f system for more info.
your best bet is to fork another process (of the other perlscript your are
calling) .
for info see:
perldoc -f fork
perldoic perlipc
and you should find tons of recent
