An OT stylistic note.

I find that explicit referencing of @_ inside of functions is problematic. It is too easy when modifying code to accidentally access this when you meant that. For which reason the two main styles you see go like:

sub FileCheck { my $file = shift; my $perm = shift; my $oot = shift; # etc } # or sub FileCheck { my ($file, $perm, $oot) = @_; # etc }
And now if you decide while developing code that you want to change the order of arguments, you are much less likely to make a mistake.

(I also don't much like StudlyCaps, but that is one of those "important irrelevancies". It is good to be consistent about naming patterns, but which consistent choice you make is irrelevant. InOtherWords I don't code that way, but there is nothing wrong with doing so.)
