portgrep

portgrep is a tool that can help to analize existing FreeBSD ports and how they use different variables and etc.

It is similar to this command:

find /usr/ports/ -name Makefile -exec grep -H STRING {} \;

Installation

• fetch current version of portgrep
• extract it
• change directory
• make
• make install

Usage

For example I want to know were and how Boost's shared_prt library is used:

portgrep Makefile shared_ptr

Output:

Found in: /usr/ports/devel/libopkele/Makefile
BUILD_DEPENDS=  ${LOCALBASE}/include/boost/shared_ptr.hpp:${PORTSDIR}/devel/boost-libs

Found in: /usr/ports/devel/monotone/Makefile
BUILD_DEPENDS=  ${LOCALBASE}/include/boost/shared_ptr.hpp:${PORTSDIR}/devel/boost-libs \
