How to change your shell?

You can easily install and remove different shells using the Software Center on Ubuntu or your preferred package manager. Shells are located in the /bin/ directory, and as long as you’re running a modern Linux distribution, it’s easy to change what your default is. Just enter the following command:

chsh

You’ll be prompted for your password, then you can change to a different shell by entering its path.

-bash-4.2$ chsh
Changing shell for jtony.
New shell [/bin/bash]: /bin/ksh
Password:
Shell changed.
-bash-4.2$
 

In square brackets, you’ll see your current default, and if you want to leave it as-is, just hit Enter.
