RSTART(1)                                                                               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-specific; 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 applications to be invoked without knowing what
               they are called on the  remote  system.   Currently,  the  only  generic  commands
               defined are Terminal, LoadMonitor, ListContexts, and ListGenericCommands.

       -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 program from the rsh  connection  used  to  start  it.
               With  this  option, responses from the helper are displayed and the resulting pro-
               gram is not detached from the connection.

NOTES
       This is a trivial implementation.  Far more sophisticated implementations 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  host-
       name  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  completely  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.
