hi there.

I've installed BackTrack 5 on my machine. I wanted to test other shells like ksh and etc....
So I used chsh command to do that. none of the other shells worked for me, but this is not my problem. my problem is that when I restarted the OS
and wanted to login again, I could not retrieve my default shell the exact message is as below:
cannot execute ksh:No such file or directory.

can anyone help me to fix this problem.

thanks in advance.
