I am working on a program that does things based on it's name... what I want to know is, can I find out how I was invoked? For instance if someone creates a symbolic link to me I would like to know.

the program is suid and ideally I'd like to allow symlinks by the Effective user, but no one else...

Arturo suggested file stat on $0 which only falls apart when the program is called from a PATH, so the directory info is not included. He suggested `which $0` as a way, maybe not the best, to get the info... anyone else have ideas?

Ideally I want to be able to do this in C and Perl, but Perl is fine for a start :)
