System or Backticks? - PERL Beginners

Hi all, Still thinking about this one. I have: my $backup = system($rdiff, args); # Send e-mail with a few details for success and failures # Success if ($backup == 0) { blah } I want to be able to stick the ouput of the $rdiff command into a strong, as well as get an exit code for it? Is this a backticks one? Gavin. -- Just getting into the best language ever... Fancy a me.uk? Just ask!!!...

    Default System or Backticks?

    Hi all,

    Still thinking about this one. I have:

    my $backup = system($rdiff, args);

    # Send e-mail with a few details for success and failures
    # Success
    if ($backup == 0) {
    blah
    }


    I want to be able to stick the ouput of the $rdiff command into a strong,
    as well as get an exit code for it?

    Is this a backticks one?

    Gavin.

    > Hi all, 

    Generally if you want the output you want backticks. The exit code is
    still available from C<$?>. And can be extracted the same as described in,

    perldoc perlvar
    perldoc -f system

    And the backticks is described specifically in,

    perldoc perlop
