Mac Daddy Monday: Dock Spacer using Terminal in OS X

What is Terminal in Mac OS?
It is simply a text-based program that lets you send commands manually to the OS and interact with it. You can do pretty much anything, because the Terminal is basically a window into another OS.

What is the Dock Spacer?
The Dock is very convenient to organize application icons. However, if you have too much items in the Dock, it is easy to get lost visually and also waste time searching the application that you want to get access.
Using the Dock Spacer lets you organize the applications in the Dock in groups, so that you have a visual clue to get to the applications. Dock Spacer is simply a ‘blank icon’ in the Dock. You are adding an invisible space between the icons to create a border.

1.     Launch Terminal. (Application/Utilities/Terminal)

2.   Type the following command.
*Copy and drag the below commands is recommended. You may type in the text on your own. Make sure the command is a single line of text. Don’t worry if your Terminal browser breaks your commands into multiple lines.

defaults write com.apple.dock persistent-apps -array-add '{tile-data={}; tile-type="spacer-tile";}'

3.     Press Enter or Return Key.
4.     Type the following command. (Case sensitive)
killall Dock
5. Your Dock will disappear and restart. On the far right side of the Dock, a invisible space will be created.
6. You can drag the invisible space as an icon, and place it where you want.
7. Type the following command in Terminal
exit

8. Quit Terminal.

If you want to remove the Dock Spacer, simply click and drag it outside of the Dock, just like other icons.
You can create as much Dock Spacer as possible.
