The other day I was writing some code for ESP32 in Arduino IDE and when I tried to upload it.. That's the error I got:
usage: esptool [-h]

After reading countless forum posts, reinstalling the ESP32 library and reconnecting my ESP32 back and forth.. Turns out to fix the issue all I needed to do is get rid of the space in the filename.. Yes! Just the space was causing this issue..

Then:

Now, when you try to click "upload":

It works!!!
Happy coding :)
