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, zshcsh, 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.

  • Ksh has the r history command that allows quickly to re-run older commands.
