Problem with Exporting a varaible from shell script

Dinesh Reddy — Wed, 14 Dec 2005 07:34:32 GMT

Hi all,

I am having the below problem in my HPUX machine.

I have an Shell script which is having some automation code. The code has a line like below.

PROJECT=MIT
export PROJECT

After running the above script I have to run one more script in which PROJECT variable will be used. But at this point I am getting blank value for PROJECT variable.

But when I set that variable from $ prompt, then it is working fine. I have tried as administrator also.

Could anyone help me to solve the above problem.

Hi,

it's a normal behavior : when you call a script from the command line a new shell is invoked to execute it. So the environnement wich you modify is that of the new shell.

To have current shell environnement modified by your script, simply invoke it with . (point)

For exemple, if your script's name is foo, and you are in the directory where foo reside, type :

. ./foo

Or if foo is /tmp/foo, type :

. /tmp/foo

Hope this will help
