title: How do I use Perl on the command line to search the output of other programs?
body: <p>As I understand (Perl is new to me) Perl can be used to script against a Unix command line. What I want to do is run (hardcoded) command line calls, and search the output of these calls for RegEx matches. Is there a way to do this simply in Perl? How?</p>
  
  <p>EDIT: Sequence here is:
  -Call another program.
  -Run a regex against its output.</p>
