A package manager is a tool that allows users to install the software packages on an operating system. Package Manager can be a graphical app, such as a software centre or a command-line device, apt-get or Pacman.
A package is usually referred to as an application, but it requires a GUI app, command-line tool or software library (other software programs). A package is an archive of files containing the configuration file and information on dependencies.
The archive file can be defined by combining a computer program and essential metadata. The system program can be created and first compiled at first. The package metadata package version, package description, contains the package description, dependencies (packages to be installed. Under the user, the command is owned by several package managers owned by the action of installing or uninstalling software packages under the user command.
The functions of a package manager are divided into six categories. They are:
With the help of some devices except the software of the package management system, system administrators can install and manage the software. For example, you may download a local administrator code (unpackaged), compile it, and then install it.
This may result in the local system status and the package manager of the State database. An additional step requires additional steps to combine reforms as a package manager or manipulate some dependencies.
Various computer systems that depend on the dynamic library linking, rather than static library linking, distribute machine instruction's libraries (executable) across applications and packages. In such systems, the typical relationships between different packages, with different packages, including the library, result in a challenge called dependency hell.
Microsoft is also known as the "DLL hell" in Windows when dealing with linked libraries. Good package management is crucial to these systems.
The configuration file's upgrades are particularly problematic with software upgrades. At least on Unix, since package managers originated as the file archiving utility extension.
In such systems, the typical relationships between different packages, with different packages, including the library, result in a challenge called dependent houses.
