Say I have this as my PS1
PS1='\[\e]0;TITLE\a\]\n\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n\$ '
it will give me this prompt

with a window title as TITLE
I understand that this part
\e]0;TITLE\a
creates the title, but I dont understand why. It just seems like some gibberish.
回答1:
The terminal driver looks for output containing that specific code (\e]0;
)and uses everything up to the \a
as the terminal window title.
