How to setup Ksh in Fedora Linux?

A Unix shell is a program that interprets the command or script and acts as an intermediary between the user and kernel of the system. Bash, zsh, csh, and fish are some examples of Unix shells.

Like Bash, Ksh (Korn Shell) is a Unix shell and scripting language which is upward compatible with sh. It was developed by David Korn in Bell Labs in the early 1980s.

Bash is the default shell on most Linux distributions but if you want you can install other shells also on your system.

Today in this article I will discuss how to install Ksh in Fedora Linux.

Ksh vs Bash

The major difference between ksh and bash are given below-

• Ksh has associative arrays and bash doesn’t also it has built-in floating-point operations.
• Bash handles getting exit codes from pipes in a cleaner way.
• Ksh has a print command which is way better than the echo command.
