Forgot to install csh, changed chell to csh and now I can't login

I forgot to install csh and changed my shell to csh in the /etc/passwd file and now I can't sign in because it says file or directory not found (/bin/csh) is there anything I can do?

Sure. You can go in with a live CD like Arch's install disk and change it back, or with a Arch live CD you can chroot into the hard drive install and use pacman to install csh.

No livecd:
boot in single user mode (at grub menu, edit the kernel line appending the number one "1" without quotes)

This execute sulogin, sulogin first search for shell in the passwd, if it fails execute /bin/sh

Good Luck

That worked great, thanks so much! Random question: Anyway to change the Percent sign (%) as the command line starter?

That can be defined in your ~/.cshrc file.  Just wondering, couldn't you have logged in as root and changed your shell back?

I always forget about that one. It really doesn't get any more simple that that.
