Hi Don,

so the
Code:
$process

is the script .sh,
Code:
$process.sh

I think your mistaken the variable script name for a name variable and then a script. they are both the same. of course i could put the hard coded name in there but its a script running it and using proper programming you should use variables when or if it changes. sorry for any miss understandings.

Quote:
The rsh utility runs the command nohup $process.sh >/dev/null > 2>&1 & on the host specified by the expansion of $HOST . Since the string $process is given to rsh inside single quotes, $process will be expanded on the system specified by the expansion of $HOST ; not on the system where you run the rsh command.
correct this is what we want to be done. one script telling another script to run in the back ground of another machine and not on the originator.

Quote:
Do you have any proof that the program that you want to run on ws1, ws2, and ws3 has been started?
yes they are all in the same room and i can just run
Code:
ps -ef | grep  <process name>

on each of the work stations 1-3, addition to this I can run the rsh through the xterm however it will hang open on the main computer/ ws4 (work station 4) which will stop after ws1 and not run the script on ws2 or ws3.

Quote:
Then try running:

Code:
rsh $HOST "nohup $process.sh >/dev/null > 2>&1 &"
which will expand both $HOST and $process on the local system.
I'm confused with this can you elaborate. why will it run on the local system or will the process call run on the local system while the process script runs on the host system.

thanks

pseudo

pseudo(1)						      General Commands Manual							 pseudo(1)

NAME

       pseudo - Starts a non-STREAMS pty interface for a STREAMS device

SYNOPSIS

       pseudo [-l] [-shell shell]

OPTIONS

       Starts  a shell process as the login shell. By default, the command starts this process as an interactive shell.  Specifies the shell to be
       started.  By default, the command starts the shell set by the SHELL environment variable.

DESCRIPTION

       The pseudo command provides an appropriate interface for STREAMS tty devices that are installed on  systems  configured	to  use  the  non-
       STREAMS pty driver.

       The  pseudo  command  opens a pair of master and slave pty devices, and starts a shell process. The command's options allow you to override
       the default shell specification and to specify that the process be started as a login shell.

NOTES

       The pseudo command is available only when one or more of the Tru64 UNIX optional subsets with worldwide support software are  installed	on
       your system.

       In  order  for the pseudo command to provide a non-STREAMS pty interface for STREAMS devices, the system must be configured to use the non-
       STREAMS pty driver. If the system is configured to use the STREAMS pty driver, the command provides a STREAMS pty interface.
