Command to close terminal window When I want to close a window I type exit :

 mbp-thomas in ~
○ → exit
logout

[Opération terminée]


Then cmd + w to close the window.

Is there a way to do it with a little script like if I type quit it exit the session then close the window ?
Open Terminal.
Go to Terminal → Preferences….


Select the Settings tab, then your profile, and choose the Shell tab.
Set When the shell exits to Close if the shell exited cleanly.
