You can do grep -r <pattern> *, but I prefer:

find <directory> -type f -name <optional filename pattern> | xargs grep
<pattern>

For example:

find /usr/ports -type f -name Makefile | xargs grep -i snmp

This would search all Makefiles found anywhere in the /usr/ports tree and
grep case-insensitvely through them for the pattern "snmp".
