How to Change your Login Shell
Question: "My professor wants me to use the Korn shell(ksh), and my login shell
is the C Shell (csh - the default shell you received on ce.uml.edu) - how do I
change it?"
Answer: The chsh command changes the login shell of your username.
When altering a login shell, the chsh command displays the current login shell and
then prompts for the new one. Here are the most common shells, which are listed
in /etc/shells:
/bin/sh
/usr/bin/tcsh
/usr/bin/bash
/usr/bin/ksh
/usr/bin/sh
/usr/bin/csh
To change your shell use the chsh command:
The chsh command changes the login shell of your username.
When altering a login shell, the chsh command displays the current login shell and
then prompts for the new one. The new login shell must be one of the approved
shells listed in the /etc/shells file unless you have superuser privileges.
username=johndoe
johndoe on ce.uml.edu>/usr/bin/chsh
Old shell: /usr/bin/ksh
New shell: /usr/bin/csh
For Bash shell=/usr/bin/bash
If you want to see that the change occurred, do a finger on your username (finger
johndoe) before the change and again after the shell change.
