csh is a command language interpreter incorporating a history mechanism , job control facilities , interactive file name and user name completion, and a C-like syntax. It is used both as an interactive login shell and a shell script command processor. tcsh is an enhanced but completely compatible version of the Berkeley UNIX C shell. In most cases csh / tcsh is installed by default. All you have to do is type shell name to start using it:
$ cshOR
$ tcsh
Install csh / tcsh
In case csh is not installed, type the following command at shell prompt as per your Linux distro / version.
Install it on Debian/Ubuntu/Mint Linux
$ sudo apt-get install csh
Install it on CentOS/RHEL
# yum install tcsh
Install it on Fedora Linux
$ sudo dnf install tcsh
Set csh as default login shell
To make csh as default login shell, type the following command:
$ which tcsh
OR
$ which csh
Sample output:
/bin/csh
Note down the /bin/csh or /bin/tcsh path. To change the shell simply type
$ chsh
OR
$ chsh -s /bin/csh
