Dpkg
dpkg is the software at the base of the package management system in the free operating system Debian and its numerous derivatives. dpkg is used to install, remove, and provide information about .deb packages. dpkg (Debian Package) itself is a low-level tool. APT (Advanced Package Tool), a higher-level tool, is more commonly used than dpkg as it can fetch packages from remote locations and deal with complex package relations, such as dependency resolution. Frontends for APT, like aptitude (ncurses) and synaptic ( GTK), are used for their friendlier interfaces. The Debian package "dpkg" provides the dpkg program, as well as several other programs necessary for run-time functioning of the packaging system, including dpkg-deb, dpkg-split, dpkg-query, dpkg-statoverride, dpkg-divert and dpkg-trigger. It also includes the programs such as update-alternatives and start-stop-daemon. The install-info program used to be included as well, but was later removed as it is now developed and d ...

Deb (file Format)
deb is the format, as well as extension of the software package format for the Debian Linux distribution and its derivatives. Design Debian packages are standard Unix ar archives that include two tar archives. One archive holds the control information and another contains the installable data. dpkg provides the basic functionality for installing and manipulating Debian packages. Generally end users don't manage packages directly with dpkg but instead use the APT package management software or other APT front-ends such as aptitude ( nCurses) and synaptic ( GTK). Debian packages can be converted into other package formats and vice versa using alien, and created from source code using checkinstall or the Debian Package Maker. Some core Debian packages are available as udebs ("micro debs"), and are typically used only for bootstrapping a Debian installation. Although these files use the ''udeb'' filename extension, they adhere to the same structure specification as ordi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Debian Build Toolchain
The Debian build toolchain is a collection of software utilities used to create Debian source packages (.dsc) and Debian binary packages (.deb files) from upstream source tarballs. These tools are used in the Debian project and also in Debian-based distributions such as Ubuntu. Overview Source code for free software is typically distributed in compressed tar archives called tarballs. Debian is a binary-oriented distribution, meaning that its deb packages include precompiled binaries and data files arranged into a file system hierarchy that the software expects. The Debian build toolchain thus needs instructions on how to use the upstream build system to build correct deb packages. These instructions are stored in the debian subdirectory, which is added to the source tree for the software being packaged by the package maintainer. While it is possible to build the package directly from the modified source tree, it is standard practice to create ''source packages'', which conta ...

Synaptic (software)
Synaptic is a GTK-based graphical user interface for the APT package manager used by the Debian Linux distribution and its derivatives. Synaptic is usually used on systems based on deb packages but can also be used on systems based on RPM packages. It can be used to install, remove and upgrade software packages and to add repositories. Features * Install, remove, upgrade and downgrade single and multiple packages * System-wide upgrade * Package search utility * Manage package repositories * Find packages by name, description and several other attributes * Select packages by status, section, name or a custom filter * Sort packages by name, status, size or version * Browse available online documentation related to a package * Download the latest changelog of a package * Lock packages to the current version * Force the installation of a specific package version * Undo/Redo of selections * Built-in terminal emulator for the package manager * Allows creation of download scripts (s ...

Aptitude (software)
aptitude is a front-end to APT, the Debian package manager. It displays a list of software packages and allows the user to interactively pick packages to install or remove. It has an especially powerful search system utilizing flexible search patterns. It was initially created for Debian, but has appeared in RPM-based distributions as well. User interfaces ''aptitude'' is based on the ncurses computer terminal library, with which it provides an interface that incorporates some elements commonly seen in graphical user interfaces (GUIs) (such as pull-down menus). In addition to the ncurses interface, aptitude provides an extensive command-line interface (CLI). Even though aptitude is one executable file, it provides command-line functions similar to those of apt- family of tools (apt-get, apt-cache, apt-listchanges, etc.). aptitude also emulates most command-line arguments, allowing it to act as a full replacement for . In the past, it was recommended that aptitude and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
APT (Debian)
Advanced package tool, or APT, is a free-software user interface that works with core libraries to handle the installation and removal of software on Debian, and Debian-based Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code. Usage APT is a collection of tools distributed in a package named ''apt''. A significant part of APT is defined in a C++ library of functions; APT also includes command-line programs for dealing with packages, which use the library. Three such programs are apt, apt-get and apt-cache. They are commonly used in examples because they are simple and ubiquitous. The ''apt'' package is of "''important''" priority in all current Debian releases, and is therefore included in a default Debian installation. APT can be considered a front-end to dpkg, friendlier than the older ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsoft Windows Windows is a group of several Proprietary software, proprietary graphical user interface, graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems.
