Actually, it's six flavours, five of which are variants:
/usr/bin$ ls -li grep
16507 -r-xr-xr-x 6 root wheel 51872 4 Okt 08:52 grep
/usr/bin$ ls -li | grep 16507
16507 -r-xr-xr-x 6 root wheel 51872 4 Okt 08:52 egrep
16507 -r-xr-xr-x 6 root wheel 51872 4 Okt 08:52 fgrep
16507 -r-xr-xr-x 6 root wheel 51872 4 Okt 08:52 grep
16507 -r-xr-xr-x 6 root wheel 51872 4 Okt 08:52 zegrep
16507 -r-xr-xr-x 6 root wheel 51872 4 Okt 08:52 zfgrep
16507 -r-xr-xr-x 6 root wheel 51872 4 Okt 08:52 zgrep
Still looking for a good way of putting this information into the
manual page. And to account for the fact that zgrep.1 is actually
installed as part of the gzip distriution, not as a part of the
grep distribution.
