C Shell

The C Shell (csh) is a command-line interface used in Unix-like operating systems that allows users to interact with the computer through text commands. It provides features like scripting, command history, and job control, making it easier to automate tasks and manage files. Named after the C programming language because of its syntax similarities, csh is designed to be user-friendly for programmers and system administrators alike. It serves as both a command interpreter and scripting language, enabling efficient control over the operating system through written scripts or direct commands.
