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
               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.
