Root Problem
 

I have a little root problem. If I go to the terminal as a user and type su to login as root, i can not run any root commands such as lsmod. But if i log off and log in as root i can run lsmod. just a minor annoyance.

su - root put's root's path in place.. without the dash, your not getting root's own path.

lsmod usually resides in /sbin which isn't in regular users $PATH by default..

Do a:

su

And then once your logged in check your $PATH.

Then do:

su - root

And then check your $PATH and compare.. and that will be why you can't simply run lsmod. Either login with the dash or place the full path to the command not in your $PATH which would be /sbin/lsmod to run the command..
