Don't confuse matching with capturing:

s/$a/$b/     # $a matches and is replaced by $b
s/($a)/$1$b/ # $a matches and is captured in $1
             #   $b is appended

Note also, that you can't use character classes like "." or "\s" within the right side of the substitute operator.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
