Python in a Nutshell

Name

onecmd

Synopsis

                        c.onecmd(s)

c .cmdloop calls c .onecmd( s ) for each command line s that the user inputs. You can also call onecmd directly, if you have independently obtained a line s that you need to process as a command. Normally, subclasses do not override method onecmd. Cmd.onecmd unconditionally sets c .lastcmd= s. Then, onecmd calls do_ verb if s starts with the word verb and if the subclass supplies such a method, or else methods emptyline or default, as explained earlier. In any case, Cmd.onecmd returns the result of whatever other method it ends up calling, to be interpreted by postcmd as a termination-request flag.
