Permissions on commands


Hello all,

I'm just messing about with permissions on files, but i am wondering if it is possible to disable some commands like ls and cat?


Thanks.

yes, it is possible as root
chown root.root /bin/ls
chmod 600 /bin/ls

Not sure exacly why you would want to disable commands. If you don't want someone to list the directory or see what's in the file, don't give them any permission to it.

But yeah I guess you could change the permissions on the command itself so they can't execute it.

Keep in mind that you should only become root when you need to do something that only root can do. The rest of the time you should be a regular user.

If you limit access to commands like ls, make sure you don't lock yourself out from it for your non-root account.

Wow, you are a bad dude disabling ls. I would drop dead if I did something like that because I would forget how to change it back. Then I would really be screwed.
