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 simple:

Edit ~/.profile and put your variables as follow

$ vim ~/.profile

In file put:

MY_ENV_VAR=value

1. Save ( :wq )

2. Restart the terminal (Quit and open it again)

3. Make sure that`s all be fine:

$ echo $MY_ENV_VAR

$ value
