There are lots of CPAN modules to make this easier. If it's just a command you're running and you don't need to manage its STDIN, I'd use IO::CaptureOutput, which is my favorite swiss-army tool for capturing output either from Perl or from an external command. (So much my favorite that I took over maintainership when I needed bugs fixed and the author was non-responsive.) 

use IO::CaptureOutput qw( qxx );

my ($stdout, $stderr) = qxx( $somecommand, @args, $filename );
