If the scripts did roughly the same, they'd probably take the same time
to run, but the one I wrote accesses the filesystem far more (goes
through everything under /usr/ports and runs tests on every one of
them). The good ol' bash script by Scott just generates a list of
directories through wildcards, descends only two levels of directories,
and runs a test on one subdir per list item. I lose. I'm now onto
something else, but I'll probably tune my script to mimic the bash
script behaviour and therefore use the right approach and tools. I'm the
best example for the fact that a powerful language in the hands of an
inexperienced user often does more harm then good - with bash I'd have
been forced to come up with something similarly simple and
straightforward as Scott's script. With perl I no sooner got hold of a
powerful module than I started shooting cannons at mosquitoes. Good
lesson, at any rate.
Cheers
