Cool, that's new to me!

Maybe this form should be made more prominent, as it outclasses
all the other forms: if you misremember the suffix e.g. for 2048,
then you can simply use the multiplication with 'x':

  dd if=file1 of=file2 count=1 bs=32x2048

I didn't find that form in the info page. Is it documented there?

Have a nice day,
Berny
