Open Source Windows Grep Tools

CRGREP searches for matching text in databases, various document formats, archives and other difficult to access resources. A command line tool for name and content text matching in database tables, plain files, MS Office documents, PDF, archives, MP3 audio, image meta-data, scanned documents, maven dependencies and web resources. CRGREP will search resources within resources of any arbitrary combination or depth, so text within a document within a zip archive, and so on. Here you will find binary downloads and discussion (https://sourceforge.net/p/crgrep/discussion/) . The actual development and issue tracking can be found here: https://bitbucket.org/cryanfuse/crgrep

mgrep is a command line tool that allows users to search text files for lines matching a given regular expression. It is similar to the well-known Unix utility, grep. As a natural extension to the single-line regular expressions, mgrep is also capable of searching for multiline patterns. mgrep is not a grep replacement, but it is intended to be grep-compatible: implemented options and behavior should be the same as those of grep. mgrep is written in C++ using the Boost.Regex library. A configure/make system is provided for Linux, but its source code should compile on all platforms that have the std and Boost.Regex libraries installed.

binreplace is a command line tool to search and replace binary sequences in a file. It can be very powerful when used together with grep and sed. It uses prefix tree internally to search. It's efficient even with millions of search terms.

A command line tool for text file analyis, filtering, splitting and reporting. Runs under Java (1.5+), supports plugins written in Groovy. Has nix and win batch files in distributions.

IPGREP is a command line tool to grep IP packets out of PCAP files. It provides basic filter for IP version and IP addresses. It is written in pure C without LIBPCAP, so it should run faster.
