Korn Shell (ksh)

Korn Shell (ksh) is a command-line interface used in Unix-like operating systems, allowing users to write scripts and execute commands to manage and automate tasks. It combines features from earlier shells and adds advanced programming capabilities like variables, control structures, and pattern matching. ksh is valued for its efficiency, scripting power, and compatibility, making it a popular tool for system administrators and developers to streamline operations and customize workflows in a Unix environment.
