It's also worth noting:

1) sort(1) is not part of bash.  It's an external program.  We can advise
   you, but this is not the primary support list for any implementations
   of sort.

2) The POSIX spec for sort doesn't contain a -g option.  That's an
   extension provided by your local sort implementation.  Your local
   implementation is *probably* GNU, but only you would know this for
   certain.

3) GNU projects often do not put full documentation into their man pages.
   In the case of GNU sort, the man page says this at the end:

       Full documentation <https://www.gnu.org/software/coreutils/sort>
       or available locally via: info '(coreutils) sort invocation'

So, you might want to look in those places as well as the man page.
