Hello suman583, and welcome to the Monastery!

I can’t test the Bourne shell, as I’m currently on Windows. But for a portable solution, use the module Capture::Tiny:

use Capture::Tiny ':all';
...
my ($stdout, $stderr, @results) = capture { ... };

Or, if you want the output to STDERR interleaved with the output to STDOUT:

my $merged = capture_merged { ... };
[download]

(But note the caveat in the documentation: “STDOUT and STDERR output in the merged result are not guaranteed to be properly ordered due to buffering.”)

Hope that helps,

Are you sure that this is a problem with Perl? Does the command line work outside of Perl?

try with system()

But this should be ok, also. There is something here that we don't know

perl -e 'my $result = `ls -3 2>&1`; print $result;'
perl -e '`ls -3 2>&1`;' # <-- please note that this other one is silen
