Ok. Upgrading to 3.1.1 and was going to run  
bash \<(curl -sL [https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered](https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered))  
I am on nodejs 16 and wanted to move to 18. All I have to do is add --18 or is it --node18 and where do I add it? Inside paren? Outside paren? Searched thru forum and lots of "just add -18" to command but the syntax is eluding me.

@Paul-Reed I see you edited my answer but I can't for the life of me see what you changed.  
Can you explain what I had wrong please?

Nothing has changed, and nothing is wrong.

I was trying to stop discourse from turning the URL part of the script into a link.

But it's as good as it gets 😉

````auto

Yes Marcus, that's what I tried 😂😂

...but it's not what I wanted, as you can't see the end of script (the important bit!) without scrolling.  
What I should have done was use 1 backtick at the beginning and one at the end of the script.  
Which I've now done.
