system() executes a command and returns its exit status, as documented. If you want to capture the process's STDOUT, you'll need to use backticks (``), or open(). $output = `$selection`; $output = qx[$selection]; You can also use an array as the destination of the output, so you'll get individual lines. If you want to get STDERR as well, you'll need to use something like the (standard) IPC::Open3 module. -- Jeff "japhy" Pinyan [EMAIL PROTECTED] http://www.pobox.com/~japhy/ RPI Acacia brother #734 http://www.perlmonks.org/ http://www.cpan.org/ ** Look for "Regular Expressions in Perl" published by Manning, in 2002 ** <stu> what does y/// stand for? <tenderpuss> why, yansliterate of course.
