Sort of related, if you do "man read" you the the huge "bash" man page. It would be nice if man could be improved to take you to the "read" command within that page. Or a new command "manbash read"
This prints abridged usage help, though. You can use `info bash read`, but confusingly it might not always contain the same content as manpages.
Thanks I didn't know! So many years of searching for "read" (etc) in the huge bash man page and, of course, in the case of "read" finding many false positives. Still it would be nice if `man` could be improved to know about builtin commands - the obvious thing is something like an html anchor in the big bash man page for each built in.
