I would argue that's exactly why you should adopt this approach. As a new user, you should avoid using classic Perl "magic", and make sure your code is straight-forward and readable. The script, as I've presented it, loops over the passed file names (@ARGV
), tests to make sure you've passed file names that can be found (-e
), copies the files using a CORE module (File::Copy
) and then modifies the file with an append (perlopentut
). It tests if operations succeed and is warnings
compliant. I never use command line switches in any of my code unless I'm writing one-liners, and half that time it would have been faster just to write a proper script.
