This does nothing to your file. You need to write your data back out to a
temp file (or use the -i command-line switch) and copy the temp file to
the correct name. There was a big thread last week on editing files in
place. You might want to look back at the archives at
http://archive.develooper.com/beginners%40perl.org/ to see some different
options for editing files in place.
BTW, saying '$_ =~' in your code above is unnecessary because by default
the substition operator will match against $_.
