in reply to Help in using backtick operator

Not sure if I understand your question correctly, but I would start with:

  • chomp $date; , or better:
  • build $date without shelling out (e.g. POSIX::strftime or localtime and sprintf)
  • using a correct regular expression, e.g. if ($file =~ m/AAAA\*.*?$date/) { ... }
    Update: Missed, that there is a literal * in the filename. \$ matches literal $, not $date. Non-greedy matching is probably not necessary here, but does no harm (in response to question below). It would be a good idea to also anchor the regexp.
  • (also add use strict; and use warnings; if not already done so)

    Yeah i did notice i made a mistake in the regex. But even after making the change it isn't working. if ($file =~ m/AAAA\*$date/) is not working. I haven't understood why you used ? in the regex too.
