Shell Programming and Scripting

Good Morning
I am Trying to Create a Script that @ startup sets the DISPLAY Variable
So i can Use Plink to Start X11 Applications
(*\plink.exe **** sh display.sh; eclipse)

Tools : Xming and Putty/Plink
SSH-Connection to LinuxServer

I startet with sh and that didnt work so after sh now tcsh

Both Do Their Jobs : Meaning both set the right IPs BUT
As Soon as i leave the Script and Start a Programm the change is "lost"

More explisit : (as above) sh display.sh : sets the right IP but
script ends : and eclise starts : DISPLAY is emtpy again

Code:

#!/bin/sh
echo setting Display from
echo $DISPLAY
DISPLAY=`echo $SSH_CLIENT | cut -d " " -f1`:0; export DISPLAY
echo to $DISPLAY

@ same for tcsh

Code:

setenv DISPLAY `echo $SSH_CLIENT | cut -d " " -f1`:0

the

SH : export function gives me a

Code:

': not a valid identifier`DISPLAY

As Well as the SetEnv

TCSH : no error, but after Script there is no Display Found


Doing the Procedure "by hand" works just fine @ all shells possible
and All Programms : So it cannot be the X11 Configuration

It's not really clear to me but try to start the script in the current environtment.
Make your script executable (chmod 755) and run the script as follow:

Code:

. ./display.sh

instead of

Code:

sh display.sh

That is a Problem i tried to leave out
I tried everything i knew (basic knowledge : chmod +x , or 755, file is sown to be "execuable" *) to run the script "normal" but whatever i do i always get

Code:

./display.sh: Befehl nicht gefunden (command not found)
Exitcode 1

so i fell back @ "sh script" and "tcsh script"

Code:

[FruF]>setenv DISPLAY 1234
[FruF]>echo $DISPLAY
1234
[FruF]>sh bash.sh
Set_Display
1234
': not a valid identifier`DISPLAY
10.4.xxx.32:0
[FruF]>echo $DISPLAY
1234
[FruF]>tcsh tcsh.sh
/bin/ls: Kein Treffer.
setting Display
from 
to 10.4.xxx.32:0
[FruF]>echo $DISPLAY
1234

So The logical Explanation is :
I dont know something about scripts

the last 4 Lines :
from *empty*
... meaning the display i set (1234) was not found
to *correct ip*
... meaning setenv did well and echo shows correct ip
echo
... meaning display back to fake ip ....

I'm really confused, it should be helpful if you post the contents of bash.sh and display.sh.

Regards

The SH File

Code:

#!/bin/sh
echo from $DISPLAY
DISPLAY=`echo $SSH_CLIENT | cut -d " " -f1`:0
export DISPLAY
echo to $DISPLAY

(export Display gives Error : ': not a valid identifier`DISPLAY )


The TCSH File

Code:

#!/bin/tcsh
echo Display from $DISPLAY
setenv DISPLAY `echo $SSH_CLIENT | cut -d " " -f1`:0
echo to $DISPLAY

I don't get any error with the script, maybe someone else can bring some light in the darkness.

mnm ok
But is ur Display Set to the Correct IP After Script is done `? or does is just change the DISPLAy within the script
