[[Interface::command-line]]

ABYSS

Automates most tasks on video and audio streaming. Besides being a free/libre software, its goals are:

Move past command-line based streaming, by automating things.
Provide audio/video feedback for the volunteer at the station to monitor the streaming.

Its current features include:

Behave slightly differently according to user actions or loss of the feed.
GTK+ graphical user interface.
Ease to switch between testing mode -- for testing the audio and video chain without broadcasting -- to stream mode, which broadcasts the feeds.
In the event of main camera source failure, ABYSS changes the pipeline to fetch the video source from a backup USB webcam and then starts broadcasting again.
Each stream is actually recorded locally in three forms to allow easy post-processing: audio-only, raw-video, and audio-video.

Was used during LibrePlanet 2015 and 2016. ABYSS was previously know as Libre-Streamer.

ACDK: ACDK is a development framework with a similar target of Microsoft's .NET or Sun's ONE platform, but instead of using Basic/C# or Java as programming language, it bases C++ as core implementation language. ACDK implements the standard library packages, including acdk::lang, acdk::lang::reflect, acdk::util, acdk::io, acdk::text (including regexpr), acdk::net, acdk::sql, acdk::xml and more, as well as technologies like flexible Allocator/Garbage Collection, Threading and Unicode. With the extensions of ACDK C++ objects are available for reflection, serialization, aspect oriented class attributes and [D]ynamic [M]ethod [I]nvocation. This DMI act as an universal object oriented call interface to connect C++ with scripting languages (Java, Perl, Tcl, Python, Lisp, Visual Basic, VBScript) and standard component technologies (CORBA, COM+).

ACL2: ACL2 is a mathematical logic and a mechanical theorem prover to help you reason in the logic (which is a subset of applicative Common Lisp). The theorem prover is an ``industrial strength version of the Boyer-Moore theorem prover, Nqthm. Users can build models of all kinds of computing systems in ACL2, just as in Nqthm, even though the formal logic is Lisp. Once you've built an ACL2 model of a system, you can run it and use ACL2 to prove theorems about the model.

ADG: The ADG library (Automatic Drawing Generation) is a set of functions focused on automating the drawing of mechanical parts. It is not a CAD system but a library providing a non-interactive canvas where you can put common CAD entities such as paths, xatches and quotes, to create your technical drawings. The final result can be displayed inside a GTK+ widget or exported to any cairo available format, such as PostScript and PDF documents or PNG and SVG images.

AFT: AFT (Almost Free Text) is a document preparation system. It is mostly free form, meaning that there is little intrusive markup; AFT source documents look a lot like plain old ASCII text. It has a few rules for structuring your document, more to do with formatting your text than embedding lots of commands, and it produces all types of output (HTML, XHTML, LaTeX, roll-your-own XML, etc.). All that needs to be done is to edit a rule file. You can even customize your own rule files for specialized output

AGFL: AGFL is a parser generator for natural languages. It can cope with ambiguity, which is a must for natural languages, has a lexicon system and is quite fast. If you don't know what to think of it, think "yacc" (or "bison") without shift-reduce conflicts.

AGT: AGT is a console frontend for iptables. It lets you specify options in easy-to-read configuration files, so you can quickly make complex changes to your firewall/gateway.

ALE: 'ALE' renders high-fidelity images of real scenes by aligning and combining many similar images from a camera or scanner. The correct similarity between images is roughly that achieved by a somewhat unsteady hand holding a camera.

ALSA plugins

The Advanced Linux Sound Architecture (ALSA) provides audio and MIDI functionality to the GNU/Linux operating system. ALSA has the following significant features:

Efficient support for all types of audio interfaces, from consumer sound cards to professional multichannel audio interfaces.
Fully modularized sound drivers.
SMP and thread-safe design.
User space library (alsa-lib) to simplify application programming and provide higher level functionality.
Support for the older Open Sound System (OSS) API, providing binary compatibility for most OSS programs.

AMule: aMule is short for "all-platform eMule-like file-sharing program", or, in short, "all-platform Mule". It's a port of the well-known eMule P2P client for the eDonkey2000 file sharing network, and supports most of eMule features. It also provides a small separate Web server and command line interface to connect to a running aMule via the network.

ANDREW's Not a DVD Ripping and Encoding Wizard: ANDREW's Not a DVD Ripping and Encoding Wizard, but a command-line interface that simplifies the use of some applications to create AVI, Matroska, MP4 or OGM files from DVDs.

APSR: APSR is a TCP/IP packet sender to test firewalls and other network applications. It also includes a syn flood option, the land DoS attack, a DoS attack against tcpdump running on a UNIX-based system, a UDP-flood attack, and a ping flood option. It currently supports the following protocols: IP, TCP, UDP, ICMP, Ethernet frames and you can also build any other type of protocol using the generic option. This package was formerly known as APSEND.

ATLAS: ATLAS (Automatically Tuned Linear Algebra Software) is a system for generating high-performance mathematical libraries. It generates a library that is specifically tuned to your processor and compiler. ATLAS's purpose is to provide portably optimal linear algebra software. In particular, ATLAS provides ANSI C and Fortran 77 interfaces to the BLAS, and a subset of LAPACK.

ATSLog: The ATSlog software provides a handy web-oriented interface for viewing and analysing calls for various types of PBX (Private Branch eXchange) models.
At present the program operates successfully with Panasonic, Samsung, Hybrex, Siemens, LG, and Alcatel PBX models. If your particular type of PBX is not supported yet, we can add this functionality.

AVInfo: 'AVInfo' displays AVI, MPEG (1 and 2), OGM, MKV, and IFO (DVD) information. It returns the length of a clip, FPS, resolution, codec, audio and video bit rate, number of key frames, sound parameters, the number and type of streams, and the language for audio/subtitles. It then generates an HTML, plain text, or CSV file list with statistics.

AVideo: AVideo /ævə'dɛjo:/ is a powerful, 100% libre video and audio downloader for GNU/Linux. With your freedom and privacy a #1 priority, avideo offers you peace of mind in watching everything from world news and documentaries to the latest cat videos. AVideo builds on the power of the infamous youtube-dl to ensure that the user's liberty is not sacrificed. YouTube-DL incorporates JS, SWF, and SDK interpreters in order to deliver some functionality. However, packaging these runs contrary to delivering freedom as a number 1 priority.

AWStats: Advanced Web Statistics is a free tool that generates advanced web server access statistics graphically. This web server log analyzer works as a CGI or from command line and shows you all information your log contains, in few graphical web pages. It can analyze IIS 5.0+, Apache log files and some other web servers (log files with a personalized format are supported since version 3.0). It's the best statistics tool for web server with less than 200,000 visits a month. The program can measure visits, unique vistors, pages, domains/countries, OS busiest times, robot visits, search engine/keyword used, and HTTP errors. Statistics can be updated from a browser or your scheduler. The program also supports virtual servers.

Aafigure: ASCII art to image converter. ASCII art figures can be parsed and output as SVG, PNG, JPEG, PDF and more. This project provides a python package and a command line script.

Aardvark Shellutils

The Aardvark Shell Utils collection includes the following three utilities:

Realpath, implementation of the 'realpath' function for returning the canonicalized absolute pathname of an input path. This generates an absolute pathname with all symlinks resolved and all '.' and '..' characters removed. Many commands do not work well with relative paths or paths containing symlinks. Realpath resolves these absolute paths.
Filebase, returns the base portion of a filename, that is the filename with its extension (e.g. .txt) removed. It returns everything preceeding the last period in the input string. The period itself is not returned.
Fileext, returns the extension portion of a filename (e.g. txt). It returns everything following the last period in the input string. The period itself is not returned.

Aasm: Aasm is an advanced assembler designed to support several target architectures and output file formats using plugins. It has been designed to be easily extended and, should be considered as a good alternative to monolithic assembler development for each new target CPUs and binary file formats.

Abc2ps: Abc2ps is a typesetting program for ABC, a code for typsetting music that uses standard ASCII characters. It reads a file containing abc code and outputs the music to another file in Postscript. The music can then displayed (i.e. using ghostview) or printed on a Postscript printer.

Abcde: 'abcde' is a frontend to cdparanoia, wget, cd-discid, id3, and your favorite Ogg/MP3/Flac encoder (Oggenc is the default). With one comand, it grabs a CD, converts each track to Ogg/MP3/Flac, and comments or ID3-tags each file. It supports multiple output in a single CD read, volume normalization, gapless encoding (with Lame), parallelization, SMP, HTTP proxies, customizable filename organization and munging, playlist generation, and remote distributed encoding via distmp3.

Abclock: 'abclock' gives a spatial representation of time. It isn't tied to the design of a mechanical clock, but instead uses the natural properties of bitmaps: straight lines and rectangles. The clock uses ordinary hours and minutes. Placement and movement of objects is analogous to mechanical clocks. Time has a symmetrical property that is reflected in the way time changes in this clock. It is clear and exact up to parts of minutes, even when the bitmap is very small.

Abcm2ps: abcm2ps is a package that converts music tunes from ABC format to PostScript. Based on abc2ps version 1.2.5, it was developed mainly to print baroque organ scores that have independant voices played on one or more keyboards, and a pedal-board. It introduces many extensions to the ABC language that make it suitable for classical music.

Abcpp: 'abcpp' is a simple yet powerful preprocessor designed for, but not limited to, ABC music files. It provides conditional output, macros, symbol renaming, and file inclusion. It was written to overcome incompatibilities between ABC packages, and to facilitate writing portable, and more readable ABC files.

Abook: Abook is a text-based addressbook program specifically designed to use with mutt mail client (although it can also be used independently). It has import filters for mutt, pine, and the Netscape addressbook, and export filters for mutt, pine, the Netscape addressbook, HTML, elm, plain text, spruce, and the GnomeCard addressbook.

Acct: The GNU Accounting utilities `ac', `accton', `last', `lastcomm', and `sa' add login and process accounting support to GNU/Linux. "Login accounting" provides summaries of system resource usage based on connect time, and "process accounting" provides summaries based on the commands executed on the system.

Achoz: will offer search and tools to reduce your data, keep it clean, fast and easy. in alpha development stage.

Ack: Ack is designed as a replacement for 99% of the uses of grep. ack is intelligent about the files it searches. It knows about certain file types, based on both the extension on the file and, in some cases, the contents of the file. Ack ignores backup files and files under CVS and .svn directories. It also highlights matches to help you see where the match was. Ack uses perl regular expressions.

Acovea: ACOVEA (Analysis of Compiler Optimizations via an Evolutionary Algorithm) implements a genetic algorithm to find the "best" options for compiling programs with the GCC C and C++ compilers. "Best" is defined as those options that produce the fastest executable program from a given source code. Acovea can also be extended to test other programming languages and non-GCC compilers.

AcpiTool: AcpiTool is a GNU/Linux ACPI client. It's a small command line application, intended to be a replacement for the apm tool. The primary target audience are laptop users, since these people are most interested in things like battery status, thermal status and the ability to suspend (sleep mode). The program simply accesses the /proc/acpi or /sysfs entries to get or set ACPI values. A computer running a Linux kernel from the 2.4.x or 2.6.x series with ACPI enabled is needed. It also supports various extensions for Toshiba, Asus, and IBM Thinkpad laptops.

Actim: Actim allows you to send and retrieve files, and to call command line programs on a target machine via emails. The application can handle both synchronous and asynchronous requests with basic security features. It has both command line and graphical user interfaces. This can be useful if, for example, your home PC does not have any access to your office workstation which is behind the company firewall.

Action Mailer: Action Mailer is a framework for designing email-service layers. These layers are used to consolidate code for sending out forgotten passwords, welcome wishes on signup, invoices for billing, and any other use case that requires a written notification to either a person or another system. Additionally, an Action Mailer class can be used to process incoming email, such as allowing a weblog to accept new posts from an email (which could even have been sent from a phone).

Action Query: jQuery and ActiveRecord, sitting in a tree...

Active: 'Active' creates a set of Web pages that lets Web surfers contribute to a shared calendar, groups listing, and multimedia news feed with discussion. It's designed to be easy to use, and easy to read the results. The program is under ongoing development as the backend for indymedia.org, and active.org.au.

Active Resources: Active Resource attempts to provide a coherent wrapper object-relational mapping for REST web services. It follows the same philosophy as Active Record, in that one of its prime aims is to reduce the amount of code needed to map to these resources.

Acts as Audited: acts_as_audited is an Active Record plugin that logs all modifications to your models in an audits table. It uses a polymorphic association to store an audit record for any of the model objects that you wish to have audited. The audit log stores the model that the change was on, the Ã¢â¬ÅactionÃ¢â¬ (create, update, destroy), a serialzied hash of the changes, and optionally the user that performed the action.

Acts as fu: When you need a dash of ActiveRecord and nothing more. Now you have no excuse for not test-driving your ActiveRecord extending plugins.

AdaControl

AdaControl verifies that Ada software meets the requirements of a number of parameterizable rules. It is not intended to supplement checks made by the compiler, but rather to search for particular violations of good-practice rules, or to check that some rules are obeyed project-wide. This package also contains the following utilities:

pfni: Print Full Name Image - expands any identifier to a

fully-qualified name

ptree: Prints a graphic representation

of an ASIS tree with corresponding source

AdaDoc: AdaDoc is a tool for Ada 95 developers. It creates an HTML file from a package specification for documentation purposes.

AdaGate: From fastrgv, a combination of Portal and Sokoban, AdaGate is a great example of OpenGL programming using the Ada language. While exploring a remote south-seas island you make a startling historical discovery. But before you can report your findings, an operational stargate transports you into a curious sequence of dungeons. Your escape will require the logical rearrangement of Zero Point Modules (ZPMs), that can roll in only two directions. Escape each level and find your way back to a beautiful lake on the surface. Uses fully modern OpenGL methods in Ada using textures, shaders and uniforms that achieves version 3.3 core profile contexts in a way that is sufficiently mainstream that it easily compiles and runs on Windows, GNU/Linux and Mac OS-X systems. This project serves as a testbed for learning the complexities of modern OpenGL and GLSL. Please read "sourceCode.txt", then download the 7Z file at https://sourceforge.net/projects/adagate/ for all source and runtime files. Simply unzip in your ./Downloads/ directory and run. No installation required.

AdaVenture: AdaVenture is intended to be a minimal extension to 3D of the original 2D Atari game named "Adventure". Set in ancient Persia, it begins outside the castle of the young King Xerxes, who inherited a golden chalice from his father, Darius the Great. Coveted by Greek foes King Leonidas of Sparta and King Minos of Crete, the chalice has been stolen. Your quest is to seek and return the royal chalice to its pedestal within the castle of Xerxes...a stealth mission to avoid open hostilities. But, there will be obstacles to overcome. You must find the keys to various realms, defend yourself against dragons and the Minotaur, avoid snakes and pesky bats who steal things only to drop them in random locations, and survive the maze of hungry beetles and the green mamba. The mazes have interconnections that are impossible in 3 dimensions, but as such, they are painstakingly exact reproductions of those in the original "Adventure" game from Atari. In fact, the "./mapRoom" subdirectory contains the original maps to help guide you. Please read "sourceCode.txt", then... Download: grab the latest 7Z file @ https://sourceforge.net/projects/adaventure/

AdacURL: AdacURL is an Ada95 binding to the popular curl library for fetching files over various protocols such as HTTP, FTP, or TELNET.

Adcd: Adcd is a CD player for GNU/Linux with a ncurses (text mode) interface. It features all the functions expected in a compact disc player, including playing selected tracks, random playing and loop mode. Also features a non-interactive mode for those who want to play their CDs while using the console for something else.

Addendat: 'Addendat' is a blogging program that accepts updates from either a CGI interface or a shell interface. It stores additions as HTML, so you can edit both entries and design in any ordinary text editor. It is configured using a simple HTML-like config file format and supports multiple blogs, even on the same page. It does not require Java or JavaScript and can publicize additions on a central hub, so users can easily find recently-updated blogs. It supports comments and archiving, can post entries to LiveJournal, and features configurable comment spam countermeasures.

Adjtimex: This program gives you raw access to the kernel time variables. For a machine connected to the Internet, or equipped with a precision oscillator or radio clock, the best way to keep the system clock correct is with xntpd. However, for a standalone intermittently connected machine, you may use adjtimex instead to at least correct for systematic drift. Adjtimex can optionally adjust the system clock using the CMOS clock as a reference, and can log times for long-term estimation of the drift rates.

Adns: adns is a DNS resolver library for C (and C++) programs, and a collection of useful DNS lookup utilities. The C library, and the command line utilities, provide a convenient interface. adns is capable of doing DNS lookups in an asynchronous, event-driven, fashion.

Adtool: 'adtool' is a *nix command line utility for Active Directory administration. Its features include user and group creation, deletion, modification, password setting, directory query, and search capabilities.

Aegis: Aegis is a transaction-based software management system. It provides a framework within which developers work on changes independently, and coordinates integrating those changes back into the master source code. The program supports geographically distributed development. Aegis supports distributed and multiple repositories, change sets, multiple lines of development, multiple simultaneous active branches, and branching to any depth. It enforces a development process which requires that change sets "work" (they must build successfuly and optionally include and pass tests) before being integrated into the project baseline. It also ensures that code reviews have been performed. The program also supports long transactions, which allows appropriately created changes to be treated as if they were projects and therefore to have changes made to them. This allows a hierarchy of changes within changes, to any depth. Each project is a separate repository, with separately configurable policies.

Aenig4: aenig4 emulates the Enigma M4 cipher machine used by the U-boot division of the German Navy during World War II. It can be used as well to emulate the Enigma I machine (M1, M2, M3).
