And then there's the issue that the output you are expecting is from a sh builtin (not the external command from my first post), but you didn't ensure that sh is executed to interpret the command. my $time = `/bin/sh -c 'time ...'`; [download]	[reply] [d/l]

What error? A usage error like the following? `Usage: time [-apvV] [-f format] [-o file] [--append] [--verbose] [--portability] [--format=format] [--output=file] [--version] [--quiet] [--help] command [arg...]` [download] The program needs an argument, a command to time. This has nothing to do with Perl.	[reply] [d/l]

You probably want to use Perl's built-in times function.	[reply]

I know the time functions but I want to store the time command output in to a variable. The time command output is printed in STDERR. How can I store the output in to a variable, you have any idea? --$ugum@r--	[reply]

The output of `time` is printed to STDERR, but after all the redirections are performed. Therefore, to capture it, you have to start `time` in a subshell. This has nothing to do with perl, though. perl -e '$a=`(time ls) 2>&1 >/dev/null`;print "[$a]"' [download]	[reply] [d/l]

Hi, please do not write your reply inside the signature divs, thanks. Related posting How about some complimentary space preceding "<!-- Node text goes above. Div tags should contain sig only -->"	[reply]
