How do i give myself OP on my mine os server, do I use the webui and how?

I need Op if I need to ban someone but I don’t know how to give myself it. Unlike most server hosting things the mineos webui doesn’t have a console

All commands you can use in-game you can use in the console (bottom of the log), just omit the ‘/’ when writing the ommand.
You can find a list of all available commands here:
