Re: [K12OSN] Making a message pop up on a thin client

[Michael Blinn <mblinn peopleplaces org>]

Here's a script that uses zenity. Thanks to sbalneaves & ogra in #ltsp who put it together a few months ago.  This goes to all connected clients but I'm sure you can modify for just one.

Invoke it with

#scriptname  "This is my message"

-Michael

#!/bin/bash

for PID in $(pgrep metacity); do
   DISPLAY=$(cat /proc/${PID}/environ | tr '\0' '\n' | grep DISPLAY | sed -e 's/DISPLAY=//')
   XAUTHORITY=$(cat /proc/${PID}/environ | tr '\0' '\n' | grep XAUTH | sed -e 's/XAUTHORITY=//')
   zenity --info --text="$1" &
done

Hey Folks,

I've always wondered about sneaky thin client tricks.  It seems like
there's got to be a way to blast some audio or pop up a message on a
thin client remotely, like from the command line.  Does anybody know how
to do that?

Thanks,
