CLI

Summary #

tags :

A command-line interpreter or command-line processor uses a command-line interface (CLI) to receive commands from a user in the form of lines of text.

This provides a means of setting parameters for the environment, invoking executables and providing information to them as to what actions they are to perform. In some cases the invocation is conditional based on conditions established by the user or previous executables.

Such access was first provided by computer terminals starting in the mid-1960s.

This provided an interactive environment not available with punched cards or other input methods.
