changing Discourse root email

[5555dimitri]

Hello, I've been following the steps to change root email upon initial install of Discourse, but always stumble at the third line of the manual, after entering this command:

irb(main):001:0> u = User.find_by_username("root")

I am getting this:
bash: syntax error near unexpected token `main'

what should I do differently?

there are only 2 commands there after the #, the rest is the command output.

So you're likely already done with that step.

You have to enter these two commands first. Maybe you can post a screenshot:

cd /app/code
gosu cloudron:cloudron bundle exec script/rails console

I appreciate your responses and apologize for my ignorance, I indeed mistook the command output for the command itself and was trying to enter wrong lines!
Now everything works and my email has been changed successfully, thank you very much!
