with a window title as TITLE

I understand that this part

\e]0;TITLE\a

creates the title, but I don't understand why. It just seems like some gibberish.

Solution

  • The terminal emulator looks for output containing that specific code (\e]0;) and uses everything up to the \a as the terminal window title.
