i actually looked at Getopt::Std in the beginning, and i don't think it's what i'm looking for. i also realized i could have been more specific about what i was trying to do. to that end, here's the relevant snippet from the existing bash script i'm trying to replicate:
as you can see, in a few of those cases, we're assigning a couple of variables at once, which is what's currently tripping me up. there's logic elsewhere that checks for which of those variables have been set, and prompts the user for anything that's missing. later on, the script simply calls 'op' - that is, whichever subroutine was defined by the flag(s) when the script was called. in bash, it was pretty easy, and i'm sure there's a way to replicate the logic in perl, i just can't get my head around it.
to be clear, the script wants to work with whatever it's given, whether it's a full set of flags & arguments, a partial set, or nothing at all...for that reason, i (think i) can't simply call a subroutine as soon as i see the flag for it (like -d for 'deliveries') because we need to finish assigning variables first, whether by looking at the rest of @ARGV or by prompting the user.
the only way i've been able to come up with is to 1) sort out any passed flags & arguments, 2) check for anything missing & poke at the user, and THEN 3) go do stuff. that seemed like the most sane approach, but i am, as i say, open to any suggestions.
I am trying to use a script to replace the header of each file, whose filename are stored within the array $test, using the sed command within a Perl script as follows:

I am completely new to perl programming. My father is helping me learn said programming language. However, I am stuck on one of the assignments he has given me, and I can't find very much help with it via google, either because I have a tiny attention span, or because I can be very very dense.
