SETTING YOUR DISPLAY

[johngiggs]

In order to set my display for an X session I have the following commands in a file:

#!/usr/bin/csh

setenv DISPLAY XXX.XXX.XX.XX:0

commands

The only problem is that if I am working from a different workstation, my IP address is obviously different. Is there a command that I can use so that it will automatically detect my IP address and use it to set my display?

127.0.0.1 is the loopback IP address of your own machine

setenv DISPLAY 127.0.0.1:0

or maybe
setenv DISPLAY localhost:0

No, localhost or 127.0.0.1 is a loopback to itself. That will pop the window up on the remote machine, not on the one he's working from.

I use the following on Solaris 8 with the Korn shell. You might be able to mod it for your purposes...

#!/bin/ksh

export TTY=$(ps -o tty|uniq|tail -1)
export DISPLAY=$(last -a `whoami`|grep ${TTY}|grep "still logged in"|head -1|awk '{print $10}'):0

This first uses [tt]ps[/tt] to get the TTY of the current process. Then [tt]last[/tt] is used to figure out where you're coming from and build the [tt]DISPLAY[/tt] variable.

Hope this helps.

Sorry - mis-read what was trying to be achieved
