MySQL MySQL is again a missing component in OS X 10.10 and needs to be  dowloaded from the MySQL site  use the  Mac OS X ver. 10.9 (x86, 64-bit), DMG Archive  version (works on 10.10). The latest version available is MySQL 5.6.21. Their is an issue with this version and Yosemite in that it won’t start on reboot – it will need to be started via command line explained below.

A non-login shell is when you start a sub-shell in the window, for example, typing bash when you have the bash shell running already. Global PATH only If you just want to edit the global PATH variable, you can put a file in /etc/paths.d with a the path you want to add. For example, we will create a file /etc/paths.d/ec2-api-tools and put the following in: /etc/paths.d/ec2-api-tools 1 /opt/aws/ec2-api-tools/bin Open a new Terminal and $PATH will reflect the chan
