G'day atanug,

For future reference, questions about Perl should be posted in Seekers of Perl Wisdom and not in Perl Monks Discussion as you've done here. The first sentence of the Perl Monks Discussion page says:

"This section is only for discussing issues pertaining to the PerlMonks web site." [original emphasis]

[Update: I see that the thread has now been moved to SoPW following consideration.]

On to your question. The Proc::Simple documentation says this about the exit_status() method:

"Returns the exit status of the process as the $! variable indicates. If the process is still running, undef is returned."

You can read about $! in perlvar - Error Variables.

You'll need to look at the child processes you're forking for answers as to why they're exiting with -1.

Title:
Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
