Re: Question relationship of builting(1) and functions refrenced through .Xr

Hi,

Builtin(1) describes shell builtin commands,
but the links in this see also section refer to:

- pages for valid, discrete programs in the base
system with identical names to these builtin commands

- the shells supplying the builtin commands

- the link that you are looking for, info(1), which we had
until FreeBSD 11 [0] and can probably be removed

For example, I have a shell builtin 'which' and I also
have a '/usr/bin/which'. I investigate suspicious links
with that command and whereis(1), but I feel like I need
to at least glance over the pages or it gets too meta.

Hope this helps!
