How to Use the Command 'pkcon' (with examples)

The pkcon command serves as a command line client for the PackageKit console program, which is used by Discover and GNOME software. It acts as an alternative to the widely known apt package manager. pkcon is particularly useful for managing software packages in a user-friendly manner, enabling users to install, update, and manage software right from the terminal with a suite of straightforward commands. It enhances the ease of package management across various Linux distributions that support PackageKit.

Use Case 1: Install a Package

Code:

pkcon install package

Motivation:

There are scenarios where a user needs to quickly install software on their system. Whether it’s a new productivity tool for work or a utility to enhance system functions, efficiently managing installations is crucial. The pkcon install command simplifies this process by enabling the user to install desired packages with convenience and speed, ensuring that their system is equipped with all necessary software.

Explanation:

• pkcon: Invoke the PackageKit console client to perform package management tasks.
• install: The action to be performed by pkcon. This specifies that a package installation is to be executed.
• package: Placeholder for the name of the package that the user wishes to install. Users should replace this with the specific package name they want to install.

Example Output:

Removing unnecessary or outdated software can contribute to achieving this goal. The pkcon remove command provides a straightforward way to uninstall packages that are no longer needed, helping to maintain a clean and efficient software environment.

Explanation:

• pkcon: Command tool for performing actions related to package management.
• remove: Specifies the action to be taken, which in this case is the removal of a software package.

Use Case 5: Search for a Specific Package

Code:

pkcon search package

Motivation:

When exploring software options or looking to retrieve specific package information, users often need to search through available software repositories. By using pkcon search, users can quickly locate packages that meet certain criteria, aiding in identifying and gathering information about the software they might consider installing.

Explanation:

• pkcon: The package management command tool.
• search: Directive to pkcon to scan for a package.
• package: The term or keyword to be searched. This should be replaced with the name or partial identifier of the package you are looking for.

Example Output:

Searching by name                  [=========================]

Finished                           [=========================]

Use Case 6: List All Available Packages

Code:

pkcon get-packages

Motivation:

Listing all available packages allows users to browse through the vast selection of software that can be installed on their system. This can be particularly useful for discovering new tools and applications, enabling users to explore the full range of capabilities their system can support.

Explanation:

• pkcon: The PackageKit command line interface.
• get-packages: Requests a comprehensive list of all packages that are available for installation in the package repositories configured for the system.
