This week I updated illumos grep(1), having added support for recursive searching:
$ man -M /usr/share/man grep
...
... $ man -M /usr/share/man grep
...
-r Read all files under each directory, recursively. Fol- low symbolic links on the command line, but skip sym- links that are encountered recursively. If file is a device, FIFO, or socket, skip it. -R Read all files under each directory, recursively, fol- lowing all symbolic links.
Enjoy!
