In
computing, exit
is a
command used in many
operating system
command-line
shells and
scripting languages.
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.
Operating systems, shells and scripting languages providing this command include Microsoft MSX-DOS version 2, [1] IBM OS/2, [2] DR FlexOS, [3] HP MPE/iX, [4] KolibriOS, [5] SymbOS, [6] cmd.exe, [7] sh, ksh, Perl, AWK, PHP, TCL, PowerShell and others.
On
MS-DOS, the command is available in versions 2 and later.

DR DOS 6.0

command. It is also available in the
open source MS-DOS
emulator

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