usermod -s /bin/csd vickey not working

[vickey_20]

I m trying to change my default shell using the above command. But it says that command not found however man pages for it are accessible

You mean csh??

Well, you can edit the /etc/passwd file directly and do it manually. That is assuming /bin/csh is installed on your system, otherwise Bad Things will happen

Ya it is csh . My mistake . I did changed the shell by editing the /etc/passwd file, but I think the other way of doing it i.e

usermod -s /bin/csh vickey

us better. But this command does not work in my system, though man pages are available.
