I recently reinstalled redhat 8.0 on to my system. I finaly decided to switch over from windows because I had redhat working perfectly on dual-boot. so I formated my whole drive to put redhat on it. everything went fine and all updates went well but something is werid. when i'm a normal user then su to root it says that shutdown, modprobe and possibly other (haven't checked them all) commands aren't there.
Next I logged out and then logged on as root and modprobe and shutdown worked. I've never seen this before is it normal and if it is how do I change it so when I su I can use these commands??

thanks in advance

Try a su - or su - root for full paths when su'ing to root.

thanks much it now works. I love the almost instance responce time

What can I say, its 12:20am and I'm bored.. Glad that worked for ya..
