This list includes notable command-line interpreter (CLI) – programs that interactively interpret programming languages and provide a command-line interface (cli) into which a user can enter commands.
Most operating systems are accessible via a shell – a command line interpreter. In some cases multiple shells are available.
This category somewhat overlaps with the general programming section since an operating system shell supports programming, and the line between operating system access and general programming is sometimes less than clear. For example, some versions of BASIC served as a shell, and BASIC is also a general-purpose language.
