YAPE::Regex::Expression ist immer ganz gut, wenn man sich RegExes erklären lassen will:

Code: (dl )

The regular expression:

(?-imsx:.*?(\d+)$)

matches as follows:

NODE                     EXPLANATION
----------------------------------------------------------------------
(?-imsx:                 group, but do not capture (case-sensitive)
                         (with ^ and $ matching normally) (with . not
                         matching \n) (matching whitespace and #
                         normally):
----------------------------------------------------------------------
  .*?                      any character except \n (0 or more times
                           (matching the least amount possible))
----------------------------------------------------------------------
  (                        group and capture to \1:
----------------------------------------------------------------------
    \d+                      digits (0-9) (1 or more times (matching
                             the most amount possible))
----------------------------------------------------------------------
  )                        end of \1
----------------------------------------------------------------------
  $                        before an optional \n, and the end of the
                           string
----------------------------------------------------------------------
)                        end of grouping
----------------------------------------------------------------------

Außerdem solltest Du die substitution auf ein einzelnes Element machen, denn CPAN:

warnings gibt Dir folgende Meldung:

Code: (dl )

Applying substitution (s///) to @array will act on scalar(@array) at skript.pl line 9.

Mehr zu dem was s/// macht findest Du in perlop.

Was $1 ist, wird in perlvar erklärt.
