Yes, as will a plain "su". The dash argument to su means "execute my start-up scripts and set up my environment." Without the dash, you don't get that, meaning you also won't have root's path variable set. That means you'll hafta specify the path to things like /sbin/ifconfig (and other commands). The other argument to su is the username. Without a username specified, su assumes you mean root.

Thank you so much. "su - root" didn't work, so I gave up on the whole su thing. I was hoping there was a simple fix. Can I ask? What do you think the best actual fix for the original problem is?

1)  mv /root /home/
2) ln -s /root /home/root
3) cp -a /root /home/
4) vi /etc/passwd
5) other... please explain

Thanks again,


I came into the middle of this thread so I missed which distro you are using, but the first thing to investigate is *why* root's home dir changed. Did you by any chance add root to the LDAP tree? That shouldn't have been needed, but you could change that attribute (home directory) with LDAP tools. If root is in /etc/passwd then you could change the home directory using vipw *if* you can gain root privs. If you can use "sudo" then you can gain those privs with: sudo bash, then manually adjust you environment (export PATH= ...), make the change and done. You should still be able to use "su" (without "-") make your changes and done.

Good luck.
