Showing File name of desktop picture - OR NOT

I used a terminal command as found on this board to display my desktop picture name. And now I would like to turn this OFF, but I am not familiar enough with using terminal commands.

Here is the command I used, and it works.

defaults write com.apple.dock desktop-picture-show-debug-text -bool TRUE && killall Dock

**** How do I now undo this??

This is the user who posted this command.
