set environment variables calling script file

Question

I have a requirement where I have to set environment variables calling a script file eg:set_env.sh. set_env.sh contains all the environment variables.

export SCRIPT_DIR=/e/scripts/
...

when I call the set_env.sh from my code the variables are available in that file itself. They are not available in file where I have called the script.

What should be done so that environment variables can be retained and can be used in file which calls set_env.sh.

Using . set_env.sh works - thanks.

Answer 1

You need to do

. set_env.sh

This runs set_env.sh in your current shell, rather than starting a new one.
