it's not about updating that. It's how the command works.
su - will also load the root's environment, so it will also update the PATH variable. All the sbin directories are in the root's PATH but not in the user's path because in those directories there are commands that only root will probably want to execute.

su does not load the root's environment, so the only commands you can access without having to type the full path to the command are the ones that are in your users path.

Yes, indeed .. I am confused by the question also. su is expressly and carefully designed to do this... It becomes extremely important, both for security issues (to make sure that the su environment sees and uses exactly what it's supposed to (don't forget that it can be used to invoke users other than root!) ... and for correct operation in "chroot" situations.

oh, i understand now. I've used linux for a decent amount of time and I've never known that. Some distros act differantly but the way that you are explaning it makes sense. So if I install ndiswrapper and want to be able to run it as reg user or a su I need to copy it into my user's /sbin/ directory. Is that correct?
