What different approach? What is your main goal? sudo is the best possible way for it. Another way is to add users to root group and add permissions on the command for the group. But this is not definitely the best way and sudo is something you should be looking at.

Concur with linuxlover.chaitanya; explain why sudo is insufficient. Its exactly the situation sudo was designed for.

Is this homework? Have you read the man page for setuid? This is an example where, if it's homework, go ahead and read about setuid, but if this is practice, don't do it unless you are very knowledgeable and a bit reckless.

Agreed..... why do you reject sudo? Its purpose is to do exactly what you describe

No its not a homework. Installing of sudo is not allowed tats y i have to cum up with diffrent approach.

If it's "not allowed", then perhaps you should ask the owner / administrator of the system to help you.

Have you read the LQ Rules ?

What distribution are you using? sudo is most probably installed by default on most of the distros.
But yes, administrator can restrict its usage to limited users of his/her choice. And if you are not one of them, use the system he wants you to use. No member here will help you if you are hacking into his system.

I think i gave the wrong idea. I have to come up with a solution to run some commands which require root privleges when sudo is not installed/ or cannot be installed. I think setuid is the only method and i have implemented a soultion with it. Thanks for helping.
