Yeh - hyphen are superfluous.

I’m old… Reckon I have been secretly doing the dd on my own head… Or too much powershell in the day job.

Eta: the hyphens are there to stop the unwise copypastaing the code and trashing their system - that’s my other excuse and I am sticking to it!

And definitely don’t mention the

dd -if /dev/urandom -of /dev/sda

I mentioned it once but I think I got away with it…
