Local variable shell/new shell
Hi!
I'm trying to figure out how to reuse an "old" variable in a new bourne shell.
Am i supposed to use the export function?
If i write:

Code:
NAME="Simon"
echo $NAME

it returns Simon, but if i start a new shell and write

Code:
echo $NAME

it can't be found of course. How do i solve this?

Thanks folks!

Yes, try export, but counts only for sub shells that have been started from your original shell.

can u all focus more on the use of command EXPORT . In my pjct too i have seen, some scripts are written but many times they are storing the value as Export var = "....."
why is the export command used?

That can be written a bit more polite next time Smilie

They use export like the original poster to make variables in subsequent started shells, programs etc. available. Some programs need/expect information given by variables like paths etc. That is why.

If u check help page of export u will get info.
use following command

man export


set, unset, setenv, unsetenv, export - shell built-in functions to determine the characteristics for environmental variables of the current shell and its descendents.
