Trying to Run Vassal on an OLED Steam Deck

I’m trying to follow the instructions posted at: How To Run VASSAL on SteamDeck. I set the password and I am trying the “quick way” to install. However, when I enter the setup-vassal.sh text I got the following:

I am not sure what I did wrong.

bash setup-vassal.sh needs to be a separate command on a new line, not tacked on to the end of the first command.

Edit: Note that the first command still worked properly, you don’t need to run it again.

Thank you! That worked.
