As an aside and for comparison, the way this works on Windows is it has a "Messenger" service that is sitting waiting for messages on the LAN. This is woken up by messages sent with "net send".

rsh test004 `cd /h/test/bin`; DISPLAY=0.0; export DISPLAY; ./Msg "message here";&

The above command has the end quote in the wrong place to execute the export command on test004.
Try moving it to the end of the line?

[edit]
Also, if you can open it on display 0 just by logging in over there - why not open it remotely? (ie DISPLAY=test004:0 ; export DISPLAY ; Msg "message here" &)

see that is what i was looking for something like what you posted. thanks i will give that a try

deaconf19 · #18 11-08-2007

ok this is what i have this far
#!/bin/sh
LAST=`/etc/hosts | awk '{print $1}'`
for x in $LAST ; do
rsh ${x} `cd /h/test/bin`; DISPLAY=test004:0; export DISPLAY; Msg "message here" &

deaconf19 · #19 11-08-2007

this is what is am getting now

sh: DISPLAY=test004:0.0: is not an identifier

what does that mean
this is what i did

list="01 02 03 04"
for x in $list ; do
echo $x
rsh test0${x} export DISPLAY=test0${x}:0.0
rsh test0${x} /h/test/Msg "test test"
done

and it returns the line above with that error

You do realise the "rsh" has run to separate shells?

wouldn't the following be better?

Code:

for x in $list
do
         echo $x
         rsh test0${x} <<EOF
DISPLAY=test0${x}:0.0 /h/test/Msg "test test"
EOF
done

also you are assuming the screen is 0.0.

how do i check if it is 0.0?
$DISPLAY ?

what is EOF?
