You certainly are very skilled at using bash, but don't you find that it
is slightly less flexible than if you were to simply write the whole

benefit from it.
use File::Basename;
my @cajones=fileparse('/secret/bigfoot-dna.fas');
and, when you decide to upgrade your servers to Windows, it will continue
to work...
