in reply to Restart Long Running Perl Script

When you "exec" something, it will replace the current running script, with the new one. So you could try something like 
sub restart{
exec $0;
}

but doing that is usually a sign of a bad program design. What is the reason you need to restart? Can't you just reset the variables in the original script, and let it keep running?

    I have to restart, as the FTP server could provide completely different script than the one currently running. Will exec $0 work on Win32 ?

      Yes.

      I don't know much about windows, but if it dosn't work, you could try 
      sub restart{
  system(1, $0);  # windows trick to launch a new process
  exit;                  # will need to exit original script
}

      but maybe the windows experts will know something better.
