Re^3: explanation of passages of a Perl script

... I [crossposted] to have more info. Is that a problem?

Crossposting is not a problem, but it is considered polite to note and link to the crosspost so that the efforts of those trying to help you are not needlessly duplicated at the far-flung corners of the InterWebs. Please see What shortcuts can I use for linking to other information?

Update:

Is that a problem? if it is I will remove the post.

In general, removing a post is Frowned Upon. Updating a post to add more info is ok — like this update! Please see How do I change/delete my post?
