Csh (C Shell)

Csh, or C Shell, is a command-line interpreter for Unix-like operating systems, developed in the late 1970s. It allows users to execute commands, run scripts, and manage files through text-based input. Csh features a C-like syntax, making it familiar for programmers. It supports interactive features like command history and job control, enhancing user experience. While popular in its time, it has largely been replaced by more modern shells like Bash, but it remains significant in the history of computing for its innovations in scripting capabilities and user interface design.
