Bad shell interpreter

Shakyj · 01-14-2011, 08:47 AM

I seem to have broken my shell.

I ran "sudo update-alternatives --install /bin/bash sh /bin/sh 1"(don't ask)

Now whenever I run scripts I get bash: sh: command not found

"which sh" brings up

"-su: /usr/bin/which: /bin/sh: bad interpreter: No such file or directory"

I have a shell logged in as # but I just don't know how to fix it.

Any help would be much appreciated.

Thanks

I might try to boot from your Ubuntu Live CD, mount the hard drive, and copy the Live CD's /bin/bash into the bin directory of the hard drive.

Maybe someone else has a better idea, and I don't know what "update-alternatives" is.

It's deb lenny. If I ls /bin I can see bash and sh. But I can't see them in /usr/bin. But that gives me an idea I am going to try to scp bash and sh from the machine I am on now to the machine I broke.

That worked. Scping ubuntu's /bin/bash to the machine with the broken shell.

Thanks for the idea
