Actually, I very quickly saw what I was doing was silly. I moved to something a
little different for that portion:
my $var = `cmd -arg`;
if ($var =~ /(expr0|expr1|expr2|expr3)/) {
Do stuff;
}
This seemed to work! I was able to reuse the code for the other scenarios while
only executing the system call once which was actually a lengthy resource
intensive op. Probably a million other *and* better ways :)
Thanks for the help guys!
