I don't capitalize command names as a matter of habit, no matter where in a block of text they occur, partly because: root@thaumaturgy:/home/rob# Iptables bash: Iptables: command not found But, I agree that it can look a bit awkward. The usual fix is to use a different font and sometimes a different size or weight for text that's a command or programming idiom, and that's worked out pretty well for me too so far.
