Highlighting commands is helpfull in some pleases, and in this case at least some are helpfull: this part of a sentence (not quoted to keep the origional layout)
progress of dd once it's running
can be a bit confusing. What is that word? what do you mean by that? Now you can emphasise it by making it bold, but that's a different meta-style: you are emphasising it, not saying it is something different.
By making it
dd once it's running
It is clear that it is a command you can type, and therefore somthing to 'read' in a special way. The sentence is a bit overflowing with commands as it is, but I think it's better then the alternative: non-marked "code" / commands in a sentence that could be confusing.
If you want to improve the answer you might refrase the sentances a bit to keep the repeating mention of
dd out of there. The sentence beginning with "This will display" does mention
dd quite a bit more then needed maybe.
But overall I think it's allright as it is now.
