Maximize Editor Window at startup

I am starting the editor from the command line and would like it to be in fullscreen.

There doesn’t seem to be an option on the command line.
There’s a Window/Zoom menu item, but I haven’t found how to trigger it programmatically.

Maybe there’s a way to force the size of the main editor window, the same way one can force the GameView here, but I don’t know what type this window would be.

Any idea ?

So long as you do not have the Editor Set to open the Project Wizard at the start, you can type START /MAX Unity.exe into the command prompt. This will open the last project you had with the Editor window in Fullscreen.
