If something is a bash built-in run help blah for it’s “man page”

But yeah, man pages tick me off. Wait until you learn that there are sometimes more than one per command. I have to Google which page is which because they’re all for specific things. man foo is the equivalent of man 1 foo. What’s annoying is that the few times I’ve seen something referenced on another page the entry usually just says something like it’s on “the relevant man page” rather than just telling you exactly which.
