in thread incrementing the file

You can try starting with a "templated" filename and increment it until you get past all the existing files:

my $fn = "output000"; $fn++ while -e $fn;

At that point, you'll have a filename that is just past the last one of that pattern. Minor caveat: make sure you have enough zeroes at the end of the template - or you'll start incrementing the characters. Yes, really.

ben@feynman:~$ perl -wle'$number = "one"; $number++ for 1..3624; print + $number' two
