Environment variables in Mac OS X

Question

Update: The link below does not have a complete answer. Having to set the path or variable in two places (one for GUI and one for shell) is lame.

No

Answer 1

For 2020 Mac OS X Catalina users:

Forget about other useless answers, here only two steps needed:

1. Create a file with the naming convention: priority-appname. Then copy-paste the path you want to add to PATH.

   E.g. 80-vscode with content /Applications/Visual Studio Code.app/Contents/Resources/app/bin/ in my case.

2. Move that file to /etc/paths.d/. Don't forget to open a new tab(new session) in the Terminal and type echo $PATH to check that your path is added!

Notice: this method only appends your path to PATH.
