Uname
uname (short for ''unix name'') is a computer program in Unix and Unix-like computer operating systems that prints the name, version and other details about the current machine and the operating system running on it. History The uname system call and command appeared for the first time in PWB/UNIX. Both are specified by POSIX. The GNU version of uname is included in the "sh-utils" or "coreutils" packages. uname itself is not available as a standalone program. The version of uname bundled in GNU coreutils was written by David MacKenzie. The command is available as a separate package for Microsoft Windows as part of the GnuWin32 project and the UnxUtils collection of Native (computing), native Windows API, Win32 porting, ports of common GNU Unix-like utilities. Related and similar commands * Some Unix variants, such as AT&T Corporation, AT&T UNIX System V Release 3.0, include the related setname program, used to change the values that uname reports. * The ver (command), ver comman ...

Darwin (operating System)
Darwin is an open-source Unix operating system first released by Apple Inc. in 2000. It is composed of code derived from NeXTSTEP, BSD, Mach, and other free software projects' code, as well as code developed by Apple. Darwin forms the Unix-based core set of components upon which macOS (previously OS X and Mac OS X), iOS, watchOS, tvOS, iPadOS and bridgeOS are based. It is mostly POSIX-compatible, but has never, by itself, been certified as compatible with any version of POSIX. Starting with Leopard, macOS has been certified as compatible with the Single UNIX Specification version 3 (SUSv3). History The heritage of Darwin began with Unix derivatives supplemented by aspects of NeXT's NeXTSTEP operating system (later, since version 4.0, known as OPENSTEP), first released in 1989. After Apple bought NeXT in 1996, it announced it would base its next operating system on OPENSTEP. This was developed into Rhapsody in 1997, Mac OS X Server 1.0 in 1999, Mac OS X Public Beta i ...

Ver (command)
In computing, ver (short for version) is a command in various command-line interpreters ( shells) such as COMMAND.COM, cmd.exe and 4DOS/ 4NT. It prints the name and version of the operating system, the command shell, or in some implementations the version of other commands. It is roughly equivalent to the Unix command uname. Implementations The command is available in FLEX, HDOS, DOS, FlexOS, SpartaDOS X, 4690 OS, OS/2, Windows, and ReactOS. It is also available in the open-source MS-DOS emulator DOSBox, in the KolibriOS Shell and in the EFI shell. TSC FLEX In TSC's FLEX operating system, the VER command is used to display the version number of a utility or program. In some versions the command is called VERSION. DOS The command is available in MS-DOS versions 2 and later. MS-DOS versions up to 6.22 typically derive the DOS version from the DOS kernel. This may be different from the string printed on start-up. The argument "/r" can be added to give more information and to ...

BusyBox
BusyBox is a software suite that provides several Unix utilities in a single executable file. It runs in a variety of POSIX environments such as Linux, Android, and FreeBSD, although many of the tools it provides are designed to work with interfaces provided by the Linux kernel. It was specifically created for embedded operating systems with very limited resources. The authors dubbed it "The Swiss Army knife of Embedded Linux", as the single executable replaces basic functions of more than 300 common commands. It is released as free software under the terms of the GNU General Public License v2, after controversially deciding not to move to version 3. History Origins Originally written by Bruce Perens in 1995 and declared complete for his intended usage in 1996, BusyBox initially aimed to put a complete bootable system on a single floppy disk that would serve both as a rescue disk and as an installer for the Debian distribution. Since that time, it has been extended ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UnxUtils
UnxUtils is a collection of ports of common GNU Unix-like utilities to native Win32, with executables only depending on the Microsoft C- runtime msvcrt.dll. The collection was last updated externally on April 15, 2003, by Karl M. Syring. The most recent release package available was an open-source project, UnxUtils at SourceForge, with the latest binary release in March, 2007 (though the files within are dated from the year 2000). The independent distribution included a main zip archive (UnxUtils.zip, 3,365,638 bytes) complemented by more recent updates (UnxUpdates.zip, 878,847 bytes, brought some binaries up to year 2003), but the SourceForge project has no UnxUpdates.zip package. An alternative source of Unix-like utilities for Windows is GnuWin32; it has later versions of many programs, but requires supporting files (e.g. DLLs) in many cases. The utilities included are: *agrep.exe * ansi2knr.exe * basename.exe * bc.exe *bison.exe *bunzip2.exe * bzip2.exe *bzip2recov ...

Porting
In software engineering, porting is the process of adapting software for the purpose of achieving some form of execution in a computing environment that is different from the one that a given program (meant for such execution) was originally designed for (e.g., different CPU, operating system, or third party library). The term is also used when software/hardware is changed to make them usable in different environments. Software is ''portable'' when the cost of porting it to a new platform is significantly less than the cost of writing it from scratch. The lower the cost of porting software relative to its implementation cost, the more portable it is said to be. Etymology The term "port" is derived from the Latin '' portāre'', meaning "to carry". When code is not compatible with a particular operating system or architecture, the code must be "carried" to the new system. The term is not generally applied to the process of adapting software to run with less memory on the sam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arch Linux
Arch Linux () is an independently developed, x86-64 general-purpose Linux distribution that strives to provide the latest stable versions of most software by following a rolling-release model. The default installation is a minimal base system, configured by the user to only add what is purposely required. Pacman, a package manager written specifically for Arch Linux, is used to install, remove and update software packages. Arch Linux uses a rolling release model, meaning there are no "major releases" of completely new versions of the system; a regular system update is all that is needed to obtain the latest Arch software; the installation images released every month by the Arch team are simply up-to-date snapshots of the main system components. Arch Linux has comprehensive documentation, consisting of a community-run wiki known as the ArchWiki. History Inspired by CRUX, another minimalist distribution, Judd Vinet started the Arch Linux project in March 2002. The name w ...

XServe
Xserve is a line of rack unit computers designed by Apple Inc. for use as servers. Introduced in 2002, it was Apple's first designated server hardware design since the Apple Network Server in 1996. In the meantime, ordinary Power Macintosh G3 and G4 models were rebranded as Macintosh Server G3 and Macintosh Server G4 with some alterations to the hardware, such as added Gigabit Ethernet cards, UltraWide SCSI cards, extra large and fast hard drives etc. and shipped with Mac OS X Server software. The Xserve initially featured one or two processors, but later switched over to the then-new transitioned to Intel with the Core 2-based Xeon offerings and subsequently switched again to two quad-core microprocessors. The Xserve could be used for a variety of applications, including file server, web server or even high-performance computing applications using clustering – a dedicated cluster Xserve, the Xserve Cluster Node, without a video card and optical drives was also availabl ...

PowerPC 970
The PowerPC 970, PowerPC 970FX, and PowerPC 970MP are 64-bit PowerPC processors from IBM introduced in 2002. When used in PowerPC-based Macintosh computers, Apple referred to them as the PowerPC G5. The 970 family was created through a collaboration between IBM and Apple. The project went under the codename GP-UL or Giga Processor Ultra Light, where Giga Processor was the codename for the POWER4 from which the core was derived. When Apple introduced the Power Mac G5, they stated that this was a five-year collaborative effort, with multi-generation roadmap. This forecast however was short-lived when Apple later had to retract its promise to deliver a 3 GHz processor only one year after its introduction. IBM was also unable to reduce power consumption to levels necessary for laptop computers. Ultimately, Apple only used three variants of the processor. IBM's JS20/JS21 blade modules and some low-end workstations and System p servers are based on the PowerPC 970. It is also ...

Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ...

Nexus 4
The Nexus 4 (codenamed Mako) is an Android smartphone co-developed by Google and LG Electronics. It is the fourth smartphone in the Google Nexus product family, unveiled on October 29, 2012, and released on November 13, 2012, and succeeded the Samsung-manufactured Galaxy Nexus. As with other Nexus devices, the Nexus 4 was sold unlocked through Google Play, but was also retailed by wireless carriers. Compared to the Galaxy Nexus, the Nexus 4 was distinguished from its predecessor by a quad-core Snapdragon S4 Pro processor, an 8 megapixel rear camera and 1.3 megapixel front camera which use the Sony BSI sensor, Qi wireless charging, and the introduction of Android 4.2 Jelly Bean, an update to the operating system which introduced 360-degree spherical photo stitching called "Photo Sphere", a quick settings menu, widgets on the lock screen, gesture typing, and an updated version of Google Now.

Android (operating System)
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with additio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
