Open Source Linux Command Line Tools

PathPicker accepts a wide range of input, output from git commands, grep results, searches, pretty much anything. After parsing the input, PathPicker presents you with a nice UI to select which files you're interested in. After that you can open them in your favorite editor or execute arbitrary commands. Facebook PathPicker is a simple command line tool that solves the perpetual problem of selecting files out of bash output. Bash is fully supported and works the best. ZSH is supported as well, but won't have a few features like alias expansion in command line mode. csh/fish/rc are supported in the latest version, but might have quirks or issues in older versions of PathPicker. Note: if your default shell and current shell is not in the same family (bash/zsh... v.s. fish/rc), you need to manually export environment variable $SHELL to your current shell.

This program is a GUI for the command line tool grep and pdfgrep. Pdfgrep search text in multiple PDF files and grep can serach text in multiple text files. You can use regular expressions for the search (https://en.wikipedia.org/wiki/Regular_expression). This GUI and the command line tools work without indexing. The following options are used: -i (ignore case) and -F (fixed strings), -n (Print page number or output lines) and -H (Print the file name for each match) from the command line tool. The -r option will be done by the program itself. Performance: This GUI works well when searching in several hundreds of documents (depends on the speed of your computer and the length of the documents). Config Dir: [homedir]/.config/pdfgrepgui Available Languages: - English - German You can add your own language by editing the file [homedir]/.config/pdfgrepgui/language.set

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.

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

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.
