With following steps we can add a variable directory to Mac Os X PATH permanently, so it will be there for always.

Instructions to add PATH Variable Globally

---

First, Lets find out your current PATH value.

To do that, Within the terminal, Fire this command:

echo $PATH

This should output the paths that are exist in your PATH now:

/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

Now, Assume that we want add this path:

/Users/Android/sdk/platform-tools

To do this, We need to edit the .bash_profile and add it to the PATH variable.

Follow these simple steps:

---

1. Within the Terminal, run vim ~/.bash_profile

2. Type i and then paste the following at the top of the file:

    export PATH=/Users/Android/sdk/platform-tools:$PATH
   

3. Hit ESC, Type :wq, and hit Enter

4. In Terminal, run source ~/.bash_profile

5. In Terminal, type in echo $PATH again and look for the updated string. If everything was successful, It should output the new path to your directory.

this is the updated PATH for me:

/Users/Android/sdk/platform-tools:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

6. In case it doesn't output the correct path, try closing the terminal window (exit fully) and open again, it should apply the changes (Restart in short).
