If you have no incentive to learn Perl, or how to read the comments and work out which parts aren't needed to complete the task you've been given, perhaps it's best to tell the person who assigned you this task that you don't "have alot of time for it" and that you're "not a scriptwriter, nor does my job require me to do/learn it". It's pretty well commented, it's pretty much all done for you, there's no real short cut.

Writing a script on your own to achieve this task will be out of the question if you refuse to learn how to use the tools required to do the job.
