Hi,
some alternative approaches would be:
my $res = `$cmd`; # note that it's not "'" but "`"
# $res only stdout, this will puke out stderr
or
my $res = `$cmd 2>&1`; # redirect stderr to stdout
# $res is now both stderr and stdout
or
my $res = `$cmd 2>/dev/null`; # throw away stderr
# $res
Hi,
You can always write STDERR and STDOUT to a temp file then read the contents
of this file back in to your script.
eg
system (some_command 1>.stdout 2>.stder);
STDOUT is written to .stdout
STDERR is written to .stderr
Theres is probably a better way than this but I find this the easiest.

Don't forget to check the close for errors. If the pipe fails for some reason
close retur

Several options:
# qx() and `` are the same
$output = `prog arg1 arg2`;
$output = qx(prog arg1 arg2);
