Need Help??

You have rnahi's answer - it's a shortcut, no offence but I think it's a bit too magic for your level of perl mastery. Here are my instructions:

Learn how to open a file handle - perldoc -f open
Learn how to read the file content - perldoc perlop look for the <> operator.
Learn Perl regular expressions - perldoc perlre
Learn the substitution operator perldoc perlop look for s/PATTERN/REPLACEMENT/egimosx
Learn how to write to a file - perldoc -f print

Then the progarm should be obvious.
