Mac OS X - Adding directories to path variable

Adding new directories to path variable is really simple under Mac OS X. Just follow the next few steps:

1. Open the Terminal (press ⌘ + SPACE and type terminal).
2. Make sure that you are in your home directory
3. Type:

   echo 'export PATH=YOURDIRECTORY:$PATH' >> ~/.profil

• Don't forget to replace "YOURDIRECTORY" with your directory string. In example: /opt/local/bin
4. Re-open the terminal.

The directory you added should be available in the path variable now.
