How to setup csh/tcsh on Fedora Linux?

Csh or (C shell) is a Unix shell developed by Bill Joy and its syntax is based on the c programming language.

tcsh ( TENEX C Shell) is a Unix shell that is the improved version of the C Shell. It derives features like command line completion and command line editing from the TENEX operating system. tcsh is backward compatible with c shell.

It is the default shell in BSD-based systems like FreeBSD. In Fedora csh and tcsh refers to the same package in the package repository.

You can view how to install and use the c shell in Ubuntu.

whereis tcsh

tcsh

Now /usr/bin/tcsh is the location of tcsh that we are looking for.

To make it your default shell use the following command in your terminal.

sudo chsh -s /usr/bin/tcsh

OR you can make it the default shell for a specific user by using the following command –

sudo chsh -s /usr/bin/tcsh user_name

Now replace the user_name with the actual user in your system.

To make bash again your default shell, use the following command in your terminal-

sudo chsh -s /bin/bash
