An inexperienced systems administrator wishes to allow users to run a program owned by root. She creates a SUID-to-root shell script to accomplish this, but it does not solve the problem.
What is WRONG with the scenario described above?
1. The shell script did not export necessary environment variables.
2. She forgot to set the "sticky bit".
3. Linux does not observe the SUID bit on shell scripts.
4. Linux requires such scripts to also be SGID-to-root.
5. Her script used /bin/sh, but for this to work, /bin/tcsh is required

Hmmm... why do these questions look like they've been lifted straight out of a test? I do not disbelieve that your friend would ask you such questions, but I doubt that s/he would give you an inquisition of multiple choice questions!

Come on! If this is an attempt to get us to answer your homework/test questions, then you may be out of luck. Although, pointing you in the right direction for the answers (ie where to look) may be forthcoming.

For questions 4 and 6, check out the Kernel howto on www.tldp.org
