Types

There exist multiple different types of shells in Linux :

• Bourne Shell (sh)
• C Shell (csh or tcsh)
• Korn Shell (ksh)
• Z Shell (zsh)
• Bourne Again Shell (bash)

All of them serve a common purpose, which is to facilitate communication between the user and the operating system.

To check the shell being used, we have to use the following command:

marijan$ echo $SHELL

/bin/bash

It's possible to change the default shell using the following command :

marijan$ chsh

Enter the new value, or press enter for the default
