Are you just saying here that you open a shell, redirect cat's output to /dev/null, and then use the terminal buffer for notes? I can't quite parse out from your comment what you mean as a workflow; I checked out my copy of Unix Power Tools and didn't see anything clarifying what you mean in either Chapter 43 "Redirecting Input and Output" or flicking through section IV "Basic Editing".
If you have a few minutes and could clarify, I'd appreciate it. I love a good *nix workflow.
Yes that's it: "cat > /dev/null". Or you can even skip running cat and just "> /dev/null". You exit by typing ctrl-d which sends an EOF (and then sends all the output to /dev/null!).
cat > ~/anyrandomfile
also works if you want a persistant connection / want storage to save things
I am not sure if the noteux.com works in the same way.
I am also not sure but is there a way to create persistant terminal connections as each is going to /dev/null but its persistant and you can connect to any of it?
