Re: This is one comman you never, ever type in - whoops.
"The smart thing is to type it into an editor, and when you both agree that it's perfect, cut-and-paste (without newline)."
Copy & paste can be fat-fingered, too. Turn it into a script. I have many one-line scripts, each named with a longish descriptive name that is often longer than the actual complex, dangerous command.
