NAME
     startup - A rsh invocation of a command in many nodes

SYNOPSIS
     startup [ -f nodefile ] command
                  --------   -------

DESCRIPTION
     startup executes the specified command in the nodes that are
                                    -------
     listed in the nodefile.  If the user doesn't specify a node-
                                                            -----
     file , startup searches for ~/.nodefile  and  a  ./.nodefile
     ----
     with  that  order.   If no file is located or loaded succes-
     fully an error message is printed.

OPTIONS
     -f nodefile
        --------
          The node list is located in the file named nodefile
                                                     --------

EXAMPLES
          example% startup -f mynodes ps ux

     The startup command is used primarly  for  starting  up  the
     Tuple  Managers.   What  I  do  is to define one of the node
     variables (i.e. #0) to be the location of the Tuple  Manager
     executable for each node and then issue the command:

          example% startup -f mynodes #0

     where #0 will be ~/posybl/bin/tmanager.mips for a decstation
     and ~/posybl/bin/tmanager.sun4 for a sun-4 workstation.

FILES
      ~/.nodefile,
      ./.nodefile

BUGS (Some call them features)
     Instead, of using this command the Tuple Managers should  be
     started  by  the Internet daemon (inetd). But, it was diffi-
     cult to experiment since I am not  a  network  administrator
     and so I bypassed the problem, by using this program.

ACKNOWLEDGEMENTS
     I would like to thank everybody that helped  me  in  writing
     this  program  and  especially  I. Kavaklis for offering his
     ideas, some pieces of code, demo programs, and for being the
     first subject to test this system.
