On Mac, if you use terminal and type
$ mysql
And you get the response
$mysql command not found
open up your editor like vim and save this to your bash profile
$ cd ~
$ vim .bash_profile
PATH=${PATH}:/usr/local/mysql/bin
Save and restart Finder
In your top toolbar locate the apple icon, and go to force quit and choose Finder
You will then be able to restart Finder which in tern reloads your bash profile and now, you can use mysql as a command
$ mysql
