the confusion is that there's obviously been an update to posix (that i
didn;t know about) since i wrote sh(1). you are quoting from the 2016
edition, and sh(1) was based on the 2013 edition. from a quick scan, the
builtins hash, type, and unalias have all been added to the builtins.
so the fix is i have to update sh(1). and maybe some other man pages.
thanks for the mail,
