Bash is the shell, or command language interpreter, that will appear in the GNU operating system. Bash is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard. It offers functional improvements over sh for both programming and interactive use. In addition, most sh scripts can be run by Bash without modification.

Boa is a single-tasking HTTP server. That means that unlike traditional web servers, it does not fork for each incoming connection, nor does it fork many copies of itself to handle multiple connections. It internally multiplexes all of the ongoing HTTP connections, and forks only for CGI programs (which must be separate processes), automatic directory generation, and automatic file gunzipping. Preliminary tests show Boa is capable of handling several thousand hits per second on a 300 MHz Pentium and dozens of hits per second on a lowly 20 MHz 386/SX.

The primary design goals of Boa are speed and security. Security, in the sense of "can't be subverted by a malicious user," not "fine grained access control and encrypted communications". Boa is not intended as a feature-packed server.

Boost provides free peer-reviewed portable C++ source libraries.

The emphasis is on libraries that work well with the C++ Standard Library. Boost libraries are intended to be widely useful, and usable across a broad spectrum of applications. The Boost license encourages both commercial and non-commercial use.

We aim to establish "existing practice" and provide reference implementations so that Boost libraries are suitable for eventual standardization. Ten Boost libraries are already included in the C++ Standards Committee's Library Technical Report (TR1) as a step toward becoming part of a future C++ Standard. More Boost libraries are proposed for the upcoming TR2.

Boron is an interpreted, prototype-based, scripting language similar to Rebol. The interpreter and datatype system is a C library useful for building domain specific languages embedded in C/C++ applications.

BZip2 is a freely available, patent free (see below), high-quality data compressor. It typically compresses files to within 10% to 15% of the best available techniques (the PPM family of statistical compressors), whilst being around twice as fast at compression and six times faster at decompression.

C-ARes is a C library that performs DNS requests and name resolves asynchronously. C-ARes is a fork of the library named ARes.

E-UAE is an Amiga emulator, a program that allows you to run software designed for Amiga computers on other platforms, such as Linux or Mac OS. It is based on UAE, the original Ubiquitous Amiga Emulator, and WinUAE, the Windows version of UAE. While it owes a huge debt to these two great projects, E-UAE diverges from both, aiming to improve performance and features on a variety of host platforms.

ed is the standard text editor on the Unix operating system originally written by Ken Thompson and contains one of the first implementations of regular expressions.

GNU ed is a line-oriented text editor. It is used to create, display, modify and otherwise manipulate text files, both interactively and via shell scripts. A restricted version of ed, red, can only edit files in the current directory and cannot execute shell commands. Ed is the "standard" text editor in the sense that it is the original editor for Unix, and thus widely available. For most purposes, however, it is superseded by full-screen editors.

FAAD2 is an open source MPEG-4 and MPEG-2 AAC decoder.

The GNU Find Utilities are the basic directory searching utilities of the GNU operating system. These programs are typically used in conjunction with other programs to provide modular and powerful directory search and file locating capabilities to other commands.

FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see supported devices) just like you would an MP3 file.

FLAC stands out as the fastest and most widely supported lossless audio codec, and the only one that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API, and has several other independent implementations.

Remake of the classic Tetris game.

GNU GPerf is a perfect hash function generator. For a given list of strings, it produces a hash function and hash table, in form of C or C++ code, for looking up a value depending on the input string. The hash function is perfect, which means that the hash table has no collisions, and the hash table lookup needs a single string comparison only.

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

GNU zip is a popular data compression program written by Jean-loup Gailly for the GNU project. Mark Adler wrote the decompression part. We developed this program as a replacement for compress because of the Unisys and IBM patents covering the LZW algorithm used by compress. These patents made it impossible for us to use compress, and we needed a replacement. The superior compression ratio of gzip is just a bonus.

ICU is a mature, widely used set of portable C/C++ and Java libraries for Unicode support, software internationalization and globalization (i18n/g11n).

LCD (and its variants) is an upper-case-only typeface.  The lower-case characters are identical to the upper-case characters, with the exception of the letters "J", "M", "W", and "Y".  To see the difference between the upper- and lower-case symbols, enter the alphabet in both upper- and lower-case in your word processor, and set the font to LCD. I recommend that you use either all upper-case or all lower-case characters with this font.

Less is a free, open-source file pager. It can be found on most versions of Linux, Unix and Mac OS, as well as on many other operating systems.

Less is a program similar to more, but which allows backward movement in the file as well as forward movement. Also, less does not have to read the entire input file before starting, so with large input files it starts up faster than text editors like vi. Less uses termcap (or terminfo on some systems), so it can run on a variety of terminals. There is even limited support for hardcopy terminals.

The libffi library provides a portable, high level programming interface to various calling conventions. This allows a programmer to call any function specified by a call interface description at run-time.

FFI stands for Foreign Function Interface. A foreign function interface is the popular name for the interface that allows code written in one language to call code written in another language. The libffi library really only provides the lowest, machine dependent layer of a fully featured foreign function interface. A layer must exist above libffi that handles type conversions for values passed between the two languages.

GD is an open source code library for the dynamic creation of images by programmers. GD creates PNG, JPEG and GIF images, among other formats. It allows your code to quickly draw images complete with lines, arcs, text, multiple colors, cut and paste from other images, and flood fills. GD is commonly used to generate charts, graphics, thumbnails, and most anything else, on the fly. While not restricted to use on the web, the most common applications of GD involve web site development.

GD is written in C and various binding are available.

However, the functionality was designed to be as reusable and portable as possible.

MAD is a high-quality MPEG audio decoder. It currently supports MPEG-1 and the MPEG-2 extension to lower sampling frequencies, as well as the de facto MPEG 2.5 format. All three audio layers - Layer I, Layer II, and Layer III (i.e. MP3) - are fully implemented.

MAD does not yet support MPEG-2 multichannel audio (although it should be backward compatible with such streams) nor does it currently support AAC.

LibMPEG2 is a free library for decoding mpeg-2 and mpeg-1 video streams.

Ogg is a multimedia container format, and the native file and stream format for the Xiph.org multimedia codecs. As with all Xiph.org technology it is an open format free for anyone to use.

As with most container formats it encapsulates raw compressed data and allows the interleaving of audio and video data inside a single convenient format. Other examples of container formats are Quicktime .mov, the MPEG program stream, and AVI.

Ogg is a stream oriented container, meaning it can be written and read in one pass, making it a natural fit for internet streaming and use in processing pipelines. This stream orientation is the major design difference over other file-based container formats.

This is an open source project to develop and maintain the reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files.

Libsigc++ implements a typesafe callback system for standard C++. It allows you to define signals and to connect those signals to any callback function, either global or a member function, regardless of whether it is static or virtual.

Theora is a free and open video compression format from the Xiph.org Foundation. Like all our multimedia technology it can be used to distribute film and video online and on disc without the licensing and royalty fees or vendor lock-in associated with other formats.

Theora scales from postage stamp to HD resolution, and is considered particularly competitive at low bitrates. It is in the same class as MPEG-4/DiVX, and like the Vorbis audio codec it has lots of room for improvement as encoder technology develops.

PicoGL is a free implementation of the TinyGL library (mini-OpenGL) under the multiplatform SDL library.

Fixed Rate Pig was intended as an SDL programming example, to demonstrate the use of a fixed virtual logic frame rate together with interpolation, also known as "tweening". However, it turned into a (sort of) playable platform game, so it's more of a how-it-all-fits-together example. (No sound, though.)

Apart from fixed rate game logic, this game also demonstrates sprite animation and partial/smart display updating techniques, suitable for games and applications that need high frame rates but can do without updating the whole screen every frame.

Pkg-config is a helper tool used when compiling applications and libraries. It helps you insert the correct compiler options on the command line so an application can use gcc -o test test.c `pkg-config --libs --cflags glib-2.0` for instance, rather than hard-coding values on where to find glib (or other libraries). It is language-agnostic, so it can be used for defining the location of documentation tools, for instance.

QEMU is a generic machine emulator and virtualiser.

When used as a machine emulator, QEMU can run OSes and programs made for one machine (e.g. an ARM board) on a different machine (e.g. your own PC). By using dynamic translation, it achieves very good performance.

When used as a virtualiser, QEMU achieves near native performance by executing the guest code directly on the host CPU. A host driver called the QEMU accelerator (also known as KQEMU) is needed in this case.

The GNU Readline library provides a set of functions for use by applications that allow users to edit command lines as they are typed in. Both Emacs and vi editing modes are available. The Readline library includes additional functions to maintain a list of previously-entered command lines, to recall and perhaps reedit those lines, and perform csh-like history expansion on previous commands.

The history facilities are also placed into a separate library, the History library, as part of the build process. The History library may be used without Readline in applications which desire its capabilities.

An entirely new version of the innovative REBOL programming language.

REBOL uses "relative expressions" (context dependent dialects) to create a powerful new dimension similar to that found in natural human languages.

S3Cmd is a Ruby program that wraps S3 operations into a simple command-line tool. It is inspired by things like rsh3ll, #sh3ll, etc., but shares no code from them.

S3Sync is a Ruby program that easily transfers directories between a local directory and an S3 bucket:prefix. It behaves somewhat, but not precisely, like the RSync program.

In general, s3sync and s3cmd complement each other. s3sync is useful to perform serious synchronization operations, and s3cmd allows you to do simple things such as bucket management, listing, transferring single files, and the like.

SANE stands for "Scanner Access Now Easy" and is an application programming interface (API) that provides standardized access to any raster image scanner hardware (flatbed scanner, hand-held scanner, video- and still-cameras, frame-grabbers, etc.).

ScummVM is a program which allows you to run certain classic graphical point-and-click adventure games, provided you already have their data files. The clever part about this: ScummVM just replaces the executables shipped with the games, allowing you to play them on systems for which they were never designed!

Some of the adventures ScummVM supports include Adventure Soft's Simon the Sorcerer 1 and 2; Revolution's Beneath A Steel Sky, Broken Sword 1 and Broken Sword 2; Flight of the Amazon Queen; Wyrmkeep's Inherit the Earth; Coktel Vision's Gobliiins; Westwood Studios' The Legend of Kyrandia and games based on LucasArts' SCUMM (Script Creation Utility for Maniac Mansion) system such as Monkey Island, Day of the Tentacle, Sam and Max and more. You can find a thorough list with details on which games are supported and how well on the compatibility page [www.scummvm.org/compatibility.php]. ScummVM is continually improving, so check back often.

SDL graphics drawing primitives and other support functions wrapped up in an addon library for the Simple Direct Media (SDL) cross-platform API layer.

SDL_image is an image file loading library. It loads images as SDL surfaces, and supports the following formats: BMP, GIF, JPEG, LBM, PCX, PNG, PNM, TGA, TIFF, XCF, XPM, XV.

This is a small sample cross-platform networking library.

SDL_sound is a library that handles the decoding of several popular sound file formats, such as .WAV and .MP3. It is meant to make the programmer's sound playback tasks simpler. The programmer gives SDL_sound a filename, or feeds it data directly from one of many sources, and then reads the decoded waveform data back at her leisure. If resource constraints are a concern, SDL_sound can process sound data in programmer-specified blocks. Alternately, SDL_sound can decode a whole sound file and hand back a single pointer to the whole waveform. SDL_sound can also handle sample rate, audio format, and channel conversion on-the-fly and behind-the-scenes, if the programmer desires.

This is a sample library which allows you to use TrueType fonts in your SDL applications. It comes with an example program "showfont" which displays an example string for a given TrueType font file.

Sed (streams editor) isn't really a true text editor or text processor. Instead, it is used to filter text, i.e., it takes text input and performs some operation (or set of operations) on it and outputs the modified text. Sed is typically used for extracting part of a file using pattern matching or substituting multiple occurrences of a string within a file.

SPLint is an extended implementation of the "lint" C code checker.

SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine.

The Tar program provides the ability to create tar archives, as well as various other kinds of manipulation. For example, you can use Tar on previously created archives to extract files, to store additional files, or to update or list files which were already stored.

Initially, tar archives were used to store files conveniently on magnetic tape. The name "Tar" comes from this use; it stands for tape archiver. Despite the utility's name, Tar can direct its output to available devices, files, or other programs (using pipes), it can even access remote devices or files (as archives).

The TeX typesetting engine converts markup language to Postscript or PDF and allows powerful formatting options.

This distribution includes the classical plain and LaTeX macro packages as well as several more recent developments of TeX (and LaTeX).

Texinfo is the official documentation format of the GNU project.

Texinfo uses a single source file to produce output in a number of formats, both online and printed (dvi, html, info, pdf, xml, etc.). This means that instead of writing different documents for online information and another for a printed manual, you need write only one document. And when the work is revised, you need revise only that one document.

TINY Is Not YAML. Parses and manipulates strings, text files and data objects in directory hierarchies.

Transmission is a fast, easy, and free multi-platform BitTorrent client with a focus on being lightweight yet feature-filled. On Syllable, currently only the text-mode version is available.

UnRAR is an extract-only command line version of the WinRAR archive manager. UnRAR is based on the official WinRAR source code from RARLabs and can extract from all known RAR files, including RAR3 files.

UnZip is an extraction utility for archives compressed in .zip format (also called "zipfiles"). Although highly compatible both with PKWARE's PKZIP and PKUNZIP utilities for MS-DOS and with Info-ZIP's own Zip program, the primary objectives have been portability and non-MSDOS functionality.

VLC media player is a highly portable multimedia player for various audio and video formats (MPEG-1, MPEG-2, MPEG-4, DivX, mp3, ogg, ...) as well as DVDs, VCDs, and various streaming protocols. It can also be used as a server to stream in unicast or multicast in IPv4 or IPv6 on a high-bandwidth network. It doesn't need any external codec or program to work.

Which takes one or more arguments. For each of its arguments it prints to stdout the full path of the executables that would have been executed when this argument had been entered at the shell prompt. It does this by searching for an executable or script in the directories listed in the environment variable PATH using the same algorithm as bash(1).

A Perl binding for the Expat XML parser.

XMLStarlet is a set of command line utilities (tools) which can be used to transform, query, validate, and edit XML documents and files using a simple set of shell commands in a similar way it is done for plain text files using UNIX grep, sed, awk, diff, patch, join, etc commands.

This set of command line utilities can be used by those who deal with many XML documents on a UNIX shell command prompt as well as for automated XML processing with shell scripts.

XZ Utils is free general-purpose data compression software with high compression ratio. XZ Utils were written for POSIX-like systems (GNU/Linux, *BSDs, etc.), but also work on some not-so-POSIX systems like Windows. XZ Utils are the successor to LZMA Utils.

The core of the XZ Utils compression code is based on LZMA SDK, but it has been modified quite a lot to be suitable for XZ Utils. The primary compression algorithm is currently LZMA2, which is used inside the .xz container format. With typical files, XZ Utils create 30 % smaller output than gzip and 15 % smaller output than bzip2.

XZ Utils consist of several components:
- liblzma is a compression library with API similar to that of zlib.
- xz is a command line tool with syntax similar to that of gzip.
- xzdec is a decompression-only tool smaller than the full-featured xz tool.
- A set of shell scripts (xzgrep, xzdiff, etc.) have been adapted from gzip to ease viewing, grepping, and comparing compressed files.
- Emulation of command line tools of LZMA Utils eases transition from LZMA Utils to XZ Utils.

While liblzma has a zlib-like API, liblzma doesn't include any file I/O functions. A separate I/O library is planned, which would abstract handling of .gz, .bz2, and .xz files with an easy to use API.

Yasm is a complete rewrite of the NASM assembler under the "new" BSD License.

Yasm currently supports the x86 and AMD64 instruction sets, accepts NASM and GAS assembler syntaxes, outputs binary, ELF32, ELF64, 32 and 64-bit Mach-O, RDOFF2, COFF, Win32, and Win64 object formats, and generates source debugging information in STABS, DWARF 2, and CodeView? 8 formats.

Zip is a compression and file packaging/archive utility. Although highly compatible both with PKWARE's PKZIP and PKUNZIP utilities for MS-DOS and with Info-ZIP's own UnZip, the primary objectives have been portability and other-than-MSDOS functionality.

A Massively Spiffy Yet Delicately Unobtrusive Compression Library.

Zlib is designed to be a free, general-purpose, legally unencumbered -- that is, not covered by any patents -- lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms. Unlike the LZW compression method used in Unix compress(1) and in the GIF image format, the compression method currently used in zlib essentially never expands the data. (LZW can double or triple the file size in extreme cases.) zlib's memory footprint is also independent of the input data and can be reduced, if necessary, at some cost in compression.

The compression algorithm used in zlib is essentially the same as that in gzip and Zip, namely, the `deflate' method that originated in PKWARE's PKZIP 2.x.
