Set an environment variable for an app.

[Karen Thompson]

Hi,
I need to set an environemt variable for a program running via
vncviewer. It requires a env. variable JAVA_HOME=/usr/java/jre1.6.0_31. I
have tried looking up on the web for hours and have had no luck. I am sure
this is something very easy, if I just knew how.

Thanks,

Karen

I'm extremely rusty with all things Unix, and I've never played with Linux,
but this might help.

I would think that you could just add it to the ~/.vnc/xstartup file just
after the first line (the first line is typically "#!/bin/sh" without the
quotes):

export JAVA_HOME=/usr/java/jre1.6.0_31

(I removed a period from the end of that line assuming it wasn't meant to
be part of the line.)

man vncserver :-

$HOME/.vnc/xstartup A shell script specifying X applications to
be run when a VNC desktop is started. If it doesn't
exist, vncserver will create a new one which runs a
couple of basic applications.

Specify whatever you want in there (its just a shell script).
