in thread [Solved]Easiest way to protect process from duplication.

Here's a variation that uses the __DATA__ handle.
use Fcntl qw(LOCK_EX LOCK_NB); die "Another instance is already running" unless flock DATA, LOCK_EX|L +OCK_NB;

    That actually requires a __DATA__ (or __END__) token to be present.
      Thank you too. BTW __END__,__DATA__,etc is there any general name for these tokens, (like "Labeled blocks", "builtins",...)? I'm newbie in perl so I just wanted to read about this stuff.
