add a 'e' after the g that will evaluate the replacement expression. You can
actually do this more than once if you add more than one 'e'. My suggestion
is that you should study the regexp doc that comes with perl. I dunno how u
get it, but it shud be something like:
perldoc perlre
You can get a list of perldoc topics by running the 'perldoc' command.
It has been quite some time since I have used perl on a Linux box, so i
might not be correct about the commands. Someone please correct me if I am
wrong. Also if you are doing this under windows, the activeperl docs are
arranged as html pages, and you should be able to find the regexp docs.
