linux shell not found

kususe · 03-15-2011, 11:35 AM

Customizing my shell, I set up for the user root, a shell doesn't exist.
And now, all of operation that requires root privileges, don't work.
I tried to log as root, but nothing, neither using graphic interface.
Suggestions??

Could you reset root's shell to /bin/sh ? And what did this 'customization' involve?

How could I reset root default shell?
I know that the only method in order to do this is modify enviroment variable "SHELL". But I have to be logged as root to use this solution.

At boot time, modify your Grub, so that your kernel line contains init=/bin/bash. This will start your system with the bash shell only, modify what you need to do and reboot.

I'm not completely sure, but I think you can become root for one command, even if the root shell is borked:

Code:

su -c 'vi passwd'

Will require you to enter the root password before proceeding.

--- rod.
