in reply to Ingoring Child Processes And glob()

Instead of messing with $SIG{CHLD}, either
  • Double-fork, or
  • spend some time waiting at various points in your top-level loop
For example, the following code waits for any terminated kid:
## first, reap any zombies so child CPU is proper: { my $kid = waitpid(-1, 1); if ($kid > 0) { redo; } }
This comes from my WebTechniques column on logging to a DBI database.

    Thanks a lot. I went for the second option and it is just what I needed.
    Also had a reread of the Cookbook and found it there. Doh!
