Power searching on your desktop without the pain. Perform powerful desktop searches without having to index your system using regular expressions. Graphical equivalent to find/grep. Available for Windows (JAVA) and Linux (Gnome & KDE) and easy to translate into your locale.

Search and replace operations on file content accross multiple files. Recursive operations within entire directory trees. FAR comes with support for regular expressions (regex) over multiple lines, automatic backup and various character encodings. Run grep like extractions to condense or rearrange sources, or perform bulk file renaming.

ldif-extract is a small 'grep' like tool to extract and convert data from LDIF files. It could be used standalone or also in a pipe together with other tools like ldapsearch.

LogsGrep is a unique, grep-like utility designed specifically to target log files containing multi-line entries. The primary target is Java log files (Log4J, common, ...), where it is very common to have multiline log entries (for example log entries with a stacktrace). It follows Unix philosophy, does only its primary job and expects its input to be generated by other more advanced tools (tail, cat, type, find...); There is no goal to be compatible with Unix grep. LogsGrep is written in the Java programming langue having performance and low resource usage in mind (no strings, no object creation, stream-processing).

This utility will provide grep-like functionality to return multi-line (record) matches for blank-line deliminated files such as LDIF files used by LDAP. A match on any line will return all lines from the previous blank line until the following one.

GeekGrep is a Django based social-networking system designed to get geeks connected with each other. The main feature is a database of geek codes and the ability to search them. See our project web site for a design template of the future site.

GrepClipse is an easy way to filter an Eclipse console's content through a regular expression as you'll do it on a *nix console through the commands grep -n <regexpr> <currentConsoleContent> followed by tail -nf <newConsoleContent> | grep <regexpr> helping the analysis of logs during the execution of a process.

A multiplatform visual implementation of the Unix utility grep

Provide a plugabble and configurable alternative to UNIX tools like grep, awk, tail, head, cut, sort, uniq or even some perl based scripts in a Java environment. A bit like what Apache Ant means to good old make.

Network grep, on steroids

Shell.NET is a set of console and winform applications written in C#. It features nearly 100 applications ranging from classical Unix applications like basename, cal, grep, tr, uniq, and wc, to some very unique tools like RunScript or TextTransform.

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.

cfgrep is an attempt to produce a grep-like program that uses regular expressions extended to describe context-free grammars. The largest part of the project is the C++ library developed to process those expressions.

glark offers grep-like searching of text files, with very powerful, complex regular expressions (e.g., "/foo\w+/ and /bar[^\d]*baz$/ within 4 lines of each other"), as well as highlighting of matches.
