Wow! Thanks for the quick reply! I wasn't too clear. I realise the default grep is GNU grep, and that it doesn't have the lzma-grepping support, and hence the gnu grep doesn't install these links. However, in this case (WITH_BSD_GREP not defined), GNU grep is installed as expected, but BSD grep is still installed, but instead as "bsdgrep". Prior to this change, the links were made against the installed "grep" if WITH_BSD_GREP was defined, but if WITH_BSD_GREP wasn't defined, they were *still* created, but linked instead to "bsdgrep". Now, they are only created in the former case. I.E. By default, on FreeBSD 10, GNUgrep existed as "grep" and xzgrep etc... existed as hard links to "bsdgrep". On FreeBSD 11, those links are not created, despite "bsdgrep" still being installed. I realise there are advantages of GNUgrep and also advantages of BSDgrep, hence why they are currently both available (and thanks for your work on getting bsd grep up to parity) but I don't understand why on the default install, xzgrep.. etc. are no longer linked to bsdgrep, unless there are problems with them? (I notice the 32K limit bug has been fixed) - but then if there were problems, they wouldn;t be linked whatever the configured system "grep" Hope this makes sense, I should have been asleep hours ago! Cheers, Jamie
