$s =~ s/(§[\S]*)/\[$1\]/g;

You search for a §, followed with anything but a blank and store it to $1. Then you replace it by itself surrounded by brackets. The modifier g means that you do it as often as possible.

Update: Thanks to i5513 and MidLifeXis for their improvements of my regex and for polishing my rusty knowledge! I like that in PerlMonks: by answering questions you often learn something for yourself, too :-)

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • 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! —
