Up2date
up2date, also known as the Red Hat Update Agent, is a tool used by older versions of Red Hat Enterprise Linux, CentOS and Fedora Core that downloads and installs new software and upgrades the operating system. It functions as a front-end to the RPM Package Manager and adds advanced features such as automatic dependency resolution. The file specifies where up2date will search for packages. Tool By default, Red Hat Enterprise Linux's up2date retrieves packages from a Red Hat Network (RHN) server, though users can add directories full of packages or even Debian and yum repositories if they wish. up2date on Fedora Core defaults to retrieving packages from yum repositories. Again, other sources can be added (apart from RHN, which is Red Hat Enterprise Linux Specific). As of Fedora Core 5 and Red Hat Enterprise Linux 5, up2date is no longer shipped with the distribution; yum is used instead. CentOS's up2date downloads packages from yum repositories on thCentOS Mirror Ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow Dog Updater, Modified
The Yellowdog Updater, Modified (YUM) is a free and open-source command-line package-management utility for computers running the Linux operating system using the RPM Package Manager. Though YUM has a command-line interface, several other tools provide graphical user interfaces to YUM functionality. YUM allows for automatic updates and package and dependency management on RPM-based distributions. Like the Advanced Package Tool (APT) from Debian, YUM works with software repositories (collections of packages), which can be accessed locally or over a network connection. Under the hood, YUM depends on RPM, which is a packaging standard for digital distribution of software, which automatically uses hashes and digital signatures to verify the authorship and integrity of said software; unlike some app stores, which serve a similar function, neither YUM nor RPM provide built-in support for proprietary restrictions on copying of packages by end-users. YUM is implemented as librarie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RPM Package Manager
RPM Package Manager (RPM) (originally Red Hat Package Manager, now a recursive acronym) is a free and open-source package management system. The name RPM refers to the file format and the package manager program itself. RPM was intended primarily for Linux distributions; the file format is the baseline package format of the Linux Standard Base. Although it was created for use in Red Hat Linux, RPM is now used in many Linux distributions such as PCLinuxOS, Fedora, AlmaLinux, CentOS, openSUSE, OpenMandriva and Oracle Linux. It has also been ported to some other operating systems, such as Novell NetWare (as of version 6.5 SP3), IBM's AIX (as of version 4), IBM i, and ArcaOS. An RPM package can contain an arbitrary set of files. Most RPM files are “binary RPMs” (or BRPMs) containing the compiled version of some software. There are also “source RPMs” (or SRPMs) containing the source code used to build a binary package. These have an appropriate tag in the file header tha ...

Red Hat Network
Red Hat Network (abbreviated to RHN) is a family of systems-management services operated by Red Hat. RHN makes updates, patches, and bug fixes of packages included within Red Hat Linux and Red Hat Enterprise Linux available to subscribers. Other available features include the deployment of custom content to, and the provisioning, configuration, reporting, monitoring of client systems. Users of these operating systems can then invoke the up2date or yum program to download and install updates from RHN. The updates portion of RHN is akin to other types of automatic system maintenance tools such as Microsoft Update for Microsoft Windows operating systems. The system requires a subscription to allow access to updates. On June 18, 2008 Red Hat CEO Jim Whitehurst announced plans for the RHN Satellite software to be open-sourced following the Fedora/RHEL model.

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 ser ...

Python (programming Language)
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000 and introduced new features such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support. Python 3.0, released in 2008, was a major revision that is not completely backward-compatible with earlier versions. Python 2 was discontinued with version 2.7.18 in 2020. Python consistently ranks as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU General Public License
The GNU General Public License (GNU GPL or simply GPL) is a series of widely used free software licenses that guarantee end users the Four Freedoms (Free software), four freedoms to run, study, share, and modify the software. The license was the first copyleft for general use and was originally written by the founder of the Free Software Foundation (FSF), Richard Stallman, for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. These GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. It is more restrictive than the GNU Lesser General Public License, Lesser General Public License and even further distinct from the more widely used permissive software licenses BSD licenses, BSD, MIT License, MIT, and Apache License, Apache.

Red Hat Enterprise Linux
Red Hat Enterprise Linux (RHEL) is a commercial open-source Linux distribution developed by Red Hat for the commercial market. Red Hat Enterprise Linux is released in server versions for x86-64, Power ISA, ARM64, and IBM Z and a desktop version for x86-64. Fedora Linux serves as its upstream source. All of Red Hat's official support and training, together with the Red Hat Certification Program, focuses on the Red Hat Enterprise Linux platform. The first version of Red Hat Enterprise Linux to bear the name originally came onto the market as "Red Hat Linux Advanced Server". In 2003, Red Hat rebranded Red Hat Linux Advanced Server to "Red Hat Enterprise Linux AS" and added two more variants, Red Hat Enterprise Linux ES and Red Hat Enterprise Linux WS. Red Hat uses strict trademark rules to restrict free re-distribution of their officially supported versions of Red Hat Enterprise Linux but still freely provides its source code. Third-party derivatives can be built and redistribut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CentOS
CentOS (, from Community Enterprise Operating System; also known as CentOS Linux) is a Linux distribution that provides a free and open-source community-supported computing platform, functionally compatible with its upstream source, Red Hat Enterprise Linux (RHEL). In January 2014, CentOS announced the official joining with Red Hat while staying independent from RHEL, under a new CentOS governing board. The first CentOS release in May 2004, numbered as CentOS version 2, was forked from RHEL version 2.1AS. Since version 8, CentOS officially supports the x86-64, ARM64, and POWER8 architectures, and releases up to version 6 also supported the IA-32 architecture. , AltArch releases of CentOS 7 are available for the IA-32 architecture, Power ISA, and for the ARMv7hl and AArch64 variants of the ARM architecture. CentOS 8 was released on 24 September 2019. In December 2020, Red Hat unilaterally terminated CentOS development. In response, CentOS founder Gregory Kurtzer created the R ...
