The Command property is used to specify a command and its
arguments that should be executed on the server. The output of the
command will be returned to the application and can be read using the
Read or ReadLine method. If no command is specified,
then the control will establish an interactive terminal session
instead.
The command and its arguments must follow the conventions used by
the SSH server, and the command will execute in the context of the
authenticated user. The ExitCode property can be used to
obtain the numerical exit code of the remote program, if one is
available.
