What I need to do is run an external program (this appear several times. Some are perl, python, and GNU applications). I need to catch all text from the output of the previous program if it errored out (stderr?), whether it executed properly, and its output.

This is what I have so far:
#!/usr/bin/perl -w
use strict;

open PIPE, "./foo.pl |";
my @output = <PIPE>;
close PIPE;

print "error: $?\n" if $?;
print "output: $_" foreach @output;
print "\nend.\n";

If $? is set, I know the program didn't execute properly. So that part is fine. However, this does NOT catch the stderr of "foo.pl", it is still printing to the console. If i can get that, I think this method will do everything that i need (as described above), correct?
