Setting environment variables on OS X

Question

What is the proper way to modify environment variables like PATH in OS X?

I\'ve looked on Google a little bit and found three different files to edit:

Answer 1

It's quite simple. Edit file .profile (vi, nano, Sublime Text or other text editor) file. You can found it at the ~/ directory (user directory) and set like this:

export MY_VAR=[your value here]

Example with Java home:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/current

Save it and return to the terminal.

You can reload it with:

source .profile

Or close and open your terminal window.
