Need Help??

coldhawk has asked for the wisdom of the Perl Monks concerning the following question:

I was just thinking, what would be the best way to regonize how is the program being called. What i real mean is, that im trying to find out if it's exec directly or is another perl program using it with require, and do actions based on that. I couldn't find any portable solutions to this, maybe i was searching with wrong search words, but anyway. i would appreciate of any help you may give.

If the program knows its own name, `$0` may help. After Compline, Zaxo	[reply]

perldoc -f caller is maybe also a good hint.	[reply]
