There is one more task that I am unable to solve.
If $_ was something like FYUY or fO76, I would like to remove the

Find and Replace does not work obviously as I would lose those last 3
characters that I want. I researched the map f
If you don't mind a newbie trying to help...
Since you want to replace something, using bare //'s won't do, since that's
an alias for m//; m, as in match. You want a substitution, s///.
The regex you are looking for should look something like this (Untested
code):

that is mostly a syntax difference. you can have a single expression,

Hi Uri,
I have spent half the day looking at map and I still don't get it.
I don't get the EXPR versus BLOCK and how I can treat them differently.
I think I am close but my regex is not hitting.
/@final_results = map { m/^[a-zA-Z0-9]{3,4}?$/$1/ } @just_cust_codes;
foreach (@final_results){
pr
Thanks Uri.
It is time that I learned map. I typically lean on grep and =~ for
matching patterns. But map sounds like a great solution.
Thanks again.

grep is NOT a regex function or has anything to do with regexes. get

grep doesn't give back

I am only interested in the first portion before the first hyphen.
I am able to grep to get that portion.
@grep_results1 = grep(/[a-zA-Z0-9]{2,4}-/, @sho_port_small_array);

So I have an array full of elements in the following format:
32F--sometext--x
F32-sometext12-xxx
I am only interested in the first portion before the first hyphen.
I am able to grep to get that portion.
@grep_results1 = grep(/[a-zA-Z0-9]{2,4}-/, @sho_port_small_array);
Now I want to print
11 matches
