RSTART(1)		    General Commands Manual		     RSTART(1)

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  en-
	       vironment 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  op-
	       tion, responses from the	helper are displayed and the resulting
	       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 re-
       mote 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.
