GNU grep

Grep searches one or more input files for lines containing a match to a specified pattern. By default, grep prints the matching lines.

ImageMagick

ImageMagick® is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale ... [More] , shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you may freely use, copy, modify, and distribute in both open and proprietary applications. [Less]

The MacPorts Project

The MacPorts Project's main goal is to provide an easy way to install various open-source software products on the Darwin OS family, with Mac OS X being the primary target. There are currently over 8000 ports available, with more being added on a regular basis.

ack

ack is a tool like grep, aimed at programmers with large trees of heterogeneous source code. ack is written purely in Perl, and takes advantage of the power of Perl's regular expressions. * Searches recursively through directories by default, while ignoring .svn, CVS and other VCS ... [More] directories. * ack ignores most of the crap you don't want to search * Lets you specify file types to search, as in --perl or --nohtml. * Color highlighting of search results. * Uses real Perl regular expressions, not a GNU subset. * ack is pure Perl, so consistent across all platforms. It even comes as a single standalone program with no module dependencies. [Less]

GraphicsMagick

GraphicsMagick is the swiss army knife of image processing. It provides a robust collection of tools and libraries which support reading, writing, and manipulating an image in over 88 major formats including important formats like DPX, GIF, JPEG, JPEG-2000, PNG, PDF, SVG, and TIFF. GraphicsMagick ... [More] supports huge images on systems that support large files, and has been tested with gigapixel-size images. GraphicsMagick can create new images on the fly, making it suitable for building dynamic Web applications. GraphicsMagick may be used to resize, rotate, sharpen, color reduce, or add special effects to an image and save the result in the same or differing image format. [Less]

iftop

iftop does for network usage what top(1) does for CPU usage. It listens to network traffic on a named interface and displays a table of current bandwidth usage by pairs of hosts. Handy for answering the question "why is our ADSL link so slow?".

dlib C++ Library

This project is a modern C++ library with a focus on portability and program correctness. It strives to be easy to use right and hard to use wrong. Thus, it comes with extensive documentation and thorough debugging modes. The library provides a platform abstraction layer for common tasks such as ... [More] interfacing with network services, handling threads, or creating graphical user interfaces. Additionally, the library implements many useful algorithms such as data compression routines, linked lists, binary search trees, linear algebra and matrix utilities, machine learning algorithms, XML and text parsing, and many other general utilities.

Pipe Viewer

Pipe Viewer (pv) is a terminal-based tool for monitoring the progress of data through a pipeline. It can be inserted into any normal pipeline between two processes to give a visual indication of how quickly data is passing through, how long it has taken, how near to completion it is, and an estimate ... [More] of how long it will be until completion. Additional support is available for multiple instances working in tandem, to given a visual indicator of relative throughput in a complex pipeline. See the project home page for more information. [Less]

Enum (Tool)

Replacement for GNU seq and BSD jot

xsel

XSel is a command-line program for manipulating the contents of the X selection.
