Root cannot find shell

[Geoc]

I've a RedHat 7.2 system where Root is now trying to run /usr/local/bin/tsch as its shell (as all the non-root users are configured), instead of /bin/bash (as it should be, and was), and of course, root can't find or run the file. Therefore, logging in as root is problematic . . .
So, is there a way to get root's default shell back to the way it was, without being logged in as root? (Of course, su and chsh don't do it, either)

Try copying /usr/local/bin/tcsh to /bin/tcsh or make a symbolic link (ln -s /usr/local/bin/tcsh /bin/tcsh) and see if that will work. You might also put /usr/local/bin in your path in /etc/profile so that it is in the default environment and root can see /usr/local/bin without having to have it in his path.

Without being able to log in as root, the permissions to do any of the above aren't there . . .
Therein lies the Rock and Hard place, right next to Catch-22 . . .

You'll probably have to boot to single user mode and see if you can get in and fix it that way. Meekness: Uncommon patience in planning a revenge that is worth while.
