How to disable some shell commands foe a specific user?

Let's say that I don't want to run from a 'guest' account command 'powerof' or 'reboot'

Is there any way how to deny to a specific user specific commands?

Thanks.

you mean like a c99 shell?

Yeah like OS for one.

I believe when he uses the term 'shell' he means a command terminal. I could be completely wrong tho..:whoa::right:

he did not give enough info for any of us to help him.

I know. We really need an OS to definitively tell him, most OS' have different command terminals, and ways to prevent/block access to them.

Yeah. Well in my experience, there's a shell that runs through the operating system. Then you can use a shell emulator to pass commands through it. Were you using a shell emulator? (Coded 3rd party)?

I believe he is using Fedora Core 8

Can't you do something like:

• make the users that you want to access the command to be part of the file's group.
• Then you find where the file is stored and chmod it.
• eg: chmod -c 010 /usr/bin/reboot

Yes. I'm using Fedora 8. I've tryed your solution, but then I cannot completely run that command, only from root's account.

I'm using 'Terminal' under GNOME.
