in reply to Getting a script to re-run itself

While its probably better to wrap the whole thing in a while loop, and put something like this in the loop:
last if $all_done;

Another idea would be to just put this at the end of the script:

exec '/my/script' unless $all_done;

    Even better would be to use $0 as the parameter to exec. 
       exec $0 unless $all_done;

    That way the script can move around on the filesystem and you won't need to hand edit it.

    A warning: the above doesn't work correctly under Windows. For some reason, exec $0 spawns another copy of your script in the background. If you write a small test program like: 

    print "hi!\n";
sleep 2;
exec $0;

    and run it, you get the effect of: 
    H:\>test.pl
hi!
hi!

H:\>hi!
hi!
hi!

    What exactly it is doing, I don't know :)
