Can i setuid for perl script?

Question

I made a perl script to change owner of a file owned by some other user. Script is complete. My administrator save that in /sbin directory and set uid for it using chmod u+s

Answer 1

No, you cannot use setuid aka chmod +s on scripts. The script's interpreter would be the thing that would actually need to be setuid, but doing that is a really bad idea. REALLY bad.

If you absolutely must have something written in Perl as setuid, the typical thing to do would be to make a small C wrapper that is setuid and executes the Perl script after starting. This gives you the best of both worlds in having a small and limited setuid script but still have a scripting language available to do the work.
