C Shell (csh)

C Shell (csh) is a command-line interface used on Unix-like operating systems, allowing users to interact with the computer through text commands. It provides features like scripting, command history, job control, and aliases, making it easier to automate tasks and manage processes. Designed for efficiency and usability, csh is an alternative to other shells like Bash, and is valued for its scripting capabilities and user-friendly commands. It essentially acts as a bridge between the user and the operating system, translating user instructions into actions.
