Personally, I would instead modify my existing code to include the functionality you say you want.

You might want to collect the desired file specs by accepting arguments that point to a text file that lists all the files that the user wants modified(because they are scattered about the file system) and/or a combination of path/wildcarded filenames from the command line etc... .

That way you only have to worry about code in one place to maintain.

Take a look at Getopt::Long for some ideas about what you might want to do regardless of whether you do the wrapper or incorporate the code in the main script.

Hope that is helpful...
