Environment Variables in Scripts

louisb · 01-15-2004, 03:44 PM

I'm trying to add two new variables with assigned values to my environment. I've tired the syntax a number of different ways and no results. Please see below:

JHHOME = /usr/java/OnlineHelp
JAVAHELP_HOME = /usr/java/OnlineHelp

JHHOME = "/usr/java/OnlineHelp"
JAVAHELP_HOME = "/usr/java/OnlineHelp"

If I key them in via a terminal window they work fine. Whe placed in a script the result are null. What I'm i missing here?

I also perform an echo $JHHOME and $JAVAHELP_HOME and results are null. Am I missing something simple here?

What shoud they look like in a script file. I am sourcing the script file correctly correctly as ". ./usr/scripts/java_paths". I have other scripts in this file and they are working fine.

Thanks

Louis

What shell?

options gravitate from setenv var value to export var=value to set var=value to... depending on what you want to accomplish.

What your missing is to export the variables. If you're using bash (which it seems like, since you use equality signs) then you have to put export in front of every variable that you want to become an environment variable. Like this:

Code:

export JHHOME=/usr/java/OnlineHelp
export JAVAHELP_HOME=/usr/java/OnlineHelp

Another way is to just do

Code:

JHHOME=/usr/java/OnlineHelp
JAVAHELP_HOME=/usr/java/OnlineHelp

export JHHOME JAVAHELP_HOME

I've also removed the spaces around the equality signs; I think there mustn't be any.

In tcsh, you use setenv instead of export, as well as no =.
