find /home -not -group test or find /home ! -group test

The exclamation inverts the match. From man find:

 ! expr True  if  expr  is false.  This character will also usually need

 -not expr
          Same as ! expr, but not POSIX compliant.

If you want the group it does belong to in the output:

find /home ! -group test -printf "%p:%g\n"
./lots/573:root
...

Do a grep excluding the things you don't want?

How about instead you use Kyle's answer, which is a better solution. – Dave Holland Apr 15 '10 at 14:02
