Never run on one enough to learn any of those.

That's what I usually do, but I was (am) having trouble getting .shrc to actually take. Was modifying passwd to fix my own account, and decided to "fix" root at the same time -- I had changed it to csh and didn't think that was a good idea. At first changed it back to /bin/sh, and then decided to try bash as it should be a super-set. Although I think that is probably unwise. > Maybe without rebooting you can do this: Enter "su -m" (if your > non-root user is allowed to su root, then enter "chsh" and set > the root shell back to the default. su -m won't work because of the bad shell "As a security precaution, if the target user's shell is a non-standard shell (as defined by getusershell(3)) and the caller's real uid is non- zero, su will fail." > When you can successfully boot into SUM, you will be prompted for > the shell to start. /bin/sh is the default shell (even though it > is a quite ugly dialog shell -- still it's considered a "maintenance > and emergency use only shell" at this point.
