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.
Today in this article I will discuss how to set up tcsh on Fedora Linux.

How to install tcsh in Fedora
Many users who are comfortable with C programming can use it as an alternative to bash (bourne again shell). The tcsh package is available in the default Fedora repository you can directly install it by using the dnf command.
First, use the following command to update the package repository –
sudo dnf update
Next, run the given command to install tcsh on Fedora –
sudo dnf install tcsh
Press y and then enter if it asks for your confirmation.
Using tcsh in Fedora
Once the package installation is completed you can start using tcsh by executing the given command in your terminal –
Make tcsh as your default shell
To make tcsh your default shell on Fedora first, you need to find the location where the tcsh package is installed.
Use the following command to find the path of tcsh –
/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
tcsh is a good alternative to bash I hope you have successfully set up it on your Fedora system.
