Thanks.

Hi:

No, unless you are 'root', the process receiving a 'kill' must be belong to the user sending the signal.

The short answer is no although the answer actually is no, unless the effective user id is zero. If you stop and think about it a moment you would realize that this is an extremely good idea because the alternative is that any user could kill any other user's processes.

Thats right, its a good idea to look at the security feature as not to allow to kill the proccess owned by other user unless you are superuser(uid=0)

A user can kill all proccess he owns but not proccess owned by someother user.

Hi Expert,
How about HP Porcess Resource Manager has this feature?

Thanks,

I dont recall, neither would HP PRM have this feature.
Just imagine, if that happens then anyone could kill anyones proccess and make the system instable. Not possible under UNIX unless you write your own code to either switch user to the proccess owner or sudo can do this for you.
