Hi Monks,

I have a list of files like so:

lab1_set1.txt
lab1_set2.txt
lab2_set1.txt
lab2_set2.txt
lab3_set2.txt
.....
labn.set1.txt
labn_set2.txt
[download]

for each pair I want to notify the user that the set was paired and notify the user if a set is unpaired.

I currently have the files read into an array. What I don't know is how to set up the regex and use that compare the filenames. My code so far seems off track... the mental block for me is how do I traverse the array and match on a regex condition? My conceptual code below hopefully reveals the deficiency in my thinking...

 
for (@labsets) {
    if ($_ ~= /^lab\d{1}/) = [some condition] {
         print "$_ matched\n!"
     } else {
         print "print $_ did not match\n";
     }
