> but the usual procedures you find online stops working once you reboot (or close the terminal I think?) The environment isn't persistent between sessions. That means you need to make the change in a way that runs on every new session (login or new terminal window). Depending on how your system is configured: .bash_profile gets run once on every login .bashrc gets run once on every non-login new session (i.e. a new terminal window) It's typical, if using these files, to do something like this: if [ -f ~/.bashrc ]; then source ~/.bashrc fi in the .bash_profile file, putting most other things in .bashrc, such that you don't have to worry about the distinction. If you're not even using bash or bash-likes at all, but instead something like Zsh, fish, etc you'll need to set things the way they want to be set there. > They should add a simple env var GUI like Windows has that just works, and isn't terminal-specific This doesn't exist in linux, because there isn't "one place" that all possible terminals draw from. Conceivably, it's possible to write a GUI tool that reads your .bashrc file, looks for anything that resembles a variable, parses the bash code to look for ways it is set, and then present a GUI tool that could update it in common cases, but... it's way easier to just write the change in a text editor.
