PackageManagement (OneGet)

PowerShellGet is a module with commands for discovering, installing, updating, and publishing PowerShell artifacts like modules, DSC resources, role capabilities, and scripts. The Find-Command cmdlet finds PowerShell commands such as cmdlets, aliases, functions, and workflows. Find-Command searches modules in registered repositories. For each command found by Find-Command, a PSGetCommandInfo object is returned. The PSGetCommandInfo object can be sent down the pipeline to the Install-Module cmdlet. Install-Module installs the module that contains the command. DSC resources can be located using the parameters Tag and RequiredVersion. Tag displays the current version of every resource that contains the specified tag in the repository. RequiredVersion needs the ModuleName parameter and the Name parameter is optional. The Name and ModuleName parameters limit the output. Use the AllVersions parameter to display a DSC resource's available versions.

Installing, patching, and removing software packages on Linux machines is one of the common tasks every sysadmin has to do. Here is how to get started with Linux package management in Linux Red Hat-based distributions (distros). Package management is a method of installing, updating, removing, and keeping track of software updates from specific repositories (repos) in the Linux system. Linux distros often use different package management tools. Red Hat-based distros use RPM (RPM Package Manager) and YUM/DNF (Yellow Dog Updater, Modified/Dandified YUM). YUM is the primary package management tool for installing, updating, removing and managing software packages in Red Hat Enterprise Linux. YUM performs dependency resolution when installing, updating, and removing software packages. YUM can manage packages from installed repositories in the system or from .rpm packages. There are many options and commands available to use with YUM.
