Fellow Monks,

the following is the solution I choose the problem described above.

I did use demerphq's code, removed the indirect filehandles and commented it for maintenance reasons.

BTW: demerphq, is there a reason for the use of indirect filehandles? The script works without them, and it's a lot easier to maintain without them.

As demerphq noted before... the DIE is mute on Windows most of the time.

Final Code:

    # Needed for "Only allow one process of this script"-rule
    use Fcntl ':flock';
    
    INIT
    {
        open  LH, $0 
            or die "Can't open $0 for locking!\nError: $!\n";
        # lock file so that it can only be accessed 
        # by the current running script
        # DIE is mute (doesn't print to the screen) on Windows
        flock LH, LOCK_EX|LOCK_NB
            or die "$0 is already running somewhere!\n";
    }
