From: PerlFAQ Server on 17 Apr 2010 06:00 This is an excerpt from the latest version perlfaq8.pod, which comes with the standard Perl distribution. These postings aim to reduce the number of repeated questions as well as allow the community to review and update the answers. The latest version of the complete perlfaq is at http://faq.perl.org . -------------------------------------------------------------------- 8.2: How come exec() doesn't return? (contributed by brian d foy) The "exec" function's job is to turn your process into another command and never to return. If that's not what you want to do, don't use "exec". :) If you want to run an external command and still keep your Perl process going, look at a piped "open", "fork", or "system". -------------------------------------------------------------------- The perlfaq-workers, a group of volunteers, maintain the perlfaq. They are not necessarily experts in every domain where Perl might show up, so please include as much information as possible and relevant in any corrections. The perlfaq-workers also don't have access to every operating system or platform, so please include relevant details for corrections to examples that do not work on particular platforms. Working code is greatly appreciated. If you'd like to help maintain the perlfaq, see the details in perlfaq.pod.
