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

NAME
osd_cat - X on-screen file displayer SYNOPSIS
osd_cat [OPTION] [FILE]... osd_cat -b percentage|slider [OPTION] DESCRIPTION
Display FILE, or standard input, on X screen. -p, --pos=POS This option tells osd_cat where to display the text. POS can be top, middle, or bottom. The default is top. -o, --offset=OFFSET This option specifies the offset from the top or bottom of screen the text is displayed. The default is 0. -A, --align=ALIGN This option tells osd_cat where to display the text. ALIGN can be left, right or center. The default is left. -i, --indent=OFFSET This option specifies the INDENT from the left of screen the text is displayed. The default is 0. -f, --font=FONT This option specifies the FONT to be used for displaying the text. The default is fixed. -c, --color=COLOR This option specifies the COLOR to be used for displaying the text. The default is red. -d, --delay=TIME This option specifies the number of seconds the text is displayed. The default is 5 seconds. -l, --lines=LINES This option specifies the number of LINES to scroll the display over. The default is 5. -s, --shadow=OFFSET This option specifies the OFFSET of the text shadow. The default is 0, which means no text shadow is created. -S, --shadowcolour=COLOUR This option specifies the COLOUR of the text shadow. The default is black. -O, --outline=WIDTH This option specifies the WIDTH of the text outline. The default is 0, which is no outline. -u, --outlinecolour=COLOUR This option specifies the COLOUR of the text outline. The default is black. -a, --age[=SCROLL_AGE] This option affects screen redrawing. If SCROLL_AGE seconds pass before a new line is ready (for example, you're reading from a pipe), all lines are cleared at once instead of being scrolled off as new lines replace old lines. The default is 0. When no SCROLL_AGE is explicitly given, the current value from DELAY is used. -w, --wait This option also affects screen redrawing. When there is data ready to be put on screen, this option will cause osd_cat to wait until the display is clear. An alternative to scrolling. -b, --barmode=TYPE Lets you display a percentage or slider bar instead of just text. TYPE may be percentage or slider. In this mode no text is read from any file, but the following options can be used: -P, --percentage=PERCENTAGE This option specified the position of the percentage / slider bar. PERCENTAGE may be in the range from 0 to 100, the default is 50. -T, --text=TEXT This option specifies an optional TEXT which gets displayed above the percentage bar. The default is empty, so no additional text is displayed. -h, --help display help (which is often more up to date) and exit With no FILE, or when FILE is -, read standard input. AUTHOR
