How do I permanently add environment variables?

Create and Modify Environment Variables on Windows

Environment variables are a set of parameters that help the system understand the running environment and tailor its behaviour accordingly . These values can be used as input for your application and make it easy to configure your application across development, staging and production versions.

To make permanent changes to the environment variables for all new accounts, go to your /etc/skel files, such as . bashrc , and change the ones that are already there or enter the new ones . When you create new users, these /etc/skel files will be copied to the new user’s home directory.
