NAME
       rstart -	a sample implementation	of a Remote Start client

SYNOPSIS
       rstart [-c context] [-g]	[-l username] [-v] hostname command args ...

DESCRIPTION
       Rstart  is  a simple implementation of a	Remote Start client as defined
       in "A Flexible Remote Execution Protocol	Based on rsh".	It uses	rsh as
       its underlying remote execution mechanism.

OPTIONS
       -c context
	       This option specifies the context in which the command is to be
	       run.  A context specifies a general environment the program  is
	       to  be  run  in.	 The details of	this environment are host-spe-
	       cific; the intent is that the client  need  not	know  how  the
	       environment  must  be  configured.   If	omitted,  the  context
	       defaults	to X.  This should be suitable for running X  programs
	       from the	host's "usual" X installation.

       -g      Interprets  command  as	a generic command, as discussed	in the
	       protocol	document.  This	is intended to allow  common  applica-
	       tions to	be invoked without knowing what	they are called	on the
	       remote system.  Currently, the only  generic  commands  defined
	       are  Terminal,  LoadMonitor,  ListContexts, and ListGenericCom-
	       mands.

       -l username
	       This option is passed to	the underlying rsh; it	requests  that
	       the command be run as the specified user.

       -v      This  option  requests that rstart be verbose in	its operation.
	       Without this option, rstart discards output from	 the  remote's
	       rstart helper, and directs the rstart helper to detach the pro-
	       gram from the rsh connection  used  to  start  it.   With  this
	       option, responses from the helper are displayed and the result-
	       ing program is not detached from	the connection.

NOTES
       This is a trivial implementation.  Far more  sophisticated  implementa-
       tions are possible and should be	developed.

       Error  handling	is  nonexistent.   Without  -v,	error reports from the
       remote are discarded silently.  With -v,	error reports are displayed.

       The $DISPLAY environment	variable is  passed.   If  it  starts  with  a
       colon,  the  local hostname is prepended.  The local domain name	should
       be appended to unqualified host names, but isn't.

       The $SESSION_MANAGER environment	variable should	be passed, but	isn't.

       X11 authority information is passed for the current display.

       ICE  authority  information should be passed, but isn't.	 It isn't com-
       pletely clear how rstart	should select what ICE	authority  information
       to pass.

       Even  without  -v,  the sample rstart helper will leave a shell waiting
       for the program to complete.  This causes no  real  harm	 and  consumes
       relatively few resources, but if	it is undesirable it can be avoided by
       explicitly specifying the "exec"	command	to the shell, eg

	    rstart somehost exec xterm

       This is obviously dependent on the command interpreter  being  used  on
       the  remote  system;  the  example given	will work for the Bourne and C
       shells.
