If you are using Cygwin ps, you also need '-W' to see Windows processes (run 'ps -h' for a list of options). I'd do something this (TMTOWTDI): # /usr/bin/perl -w # This works regardless for both Cygwin Perl and Native Perl use strict; open( PS, "ps -W |" ) or die "Pipe from ps failed, $!\n"; my @my_array = grep { /desired string/ } <PS>; close PS or die "Error from ps, $!\n"; -- Mac :}) ** I normally forward private questions to the appropriate mail list. ** Ask Smarter: http://www.tuxedo.org/~esr/faqs/smart-questions.html Give a hobbit a fish and he eats fish for a day.
