**Command Syntax**::
- exit
+ exit [<status>]
**Synopsis**. Exit NSH. Only useful for the serial front end if
you have started some other tasks (perhaps using the ``exec``
command) and you would like to have NSH out of the way. For the
telnet front-end, ``exit`` terminates the telnet session.
+``<status>`` is the exit status of NSH, from 0 to 255. The default is
+0. A script or ``sh -c`` can use it to report a failure.
