Add to the shell PATH in MacOS

The following will add to the shell path in MacOS;

Open .bath_profile
(Don't forget [SHIFT + CMD + .] toggles displaying of hidden filed in finder.)

To ad a folder such as /Users/plisken/connectiq/bin we would add the following line to the end of .bash_profile;

export PATH="/Users/plisken/connectiq/bin:$PATH"

OR

export PATH=$PATH:/Users/plisken/connectiq/bin

and of course we can check the current $PATH by doing echo $PATH

Relaunching the terminal may be required...
