And just for kicks, FreeBSD grep is mostly option compatible with GNU grep. The missing options are: -P, --perl-regexp --no-ignore-case (but --ignore-case exists) -y (obsolete anyway) -T, --initial-tab -Z (but --null exists) --group-separator --no-group-separator --exclude-from -I (but --binary-files exists) -R, --dereference-recursive I wonder if I should create a freebsd-grep package, installing its grep as 'bsdgrep' or something....
