The command causes the shell or program to terminate. If performed within an interactive command shell, the user is logged out of their current session, and/or user's current console or terminal connection is disconnected. Typically an optional exit code can be specified, which is typically a simple integer value that is then returned to the parent process.

On MS-DOS, the command is available in versions 2 and later.[8] DR DOS 6.0[9] and Datalight ROM-DOS[10] also include an implementation of the exit command. It is also available in the open source MS-DOS emulator DOSBox.

The numerical computing environment MATLAB includes an exit function with similar functionality.[11]
