For Linux users managing RPM (Red Hat Package Manager) packages, understanding how to query installed packages is essential. This skill is particularly useful for administrators and users who need to verify installations, check updates, and ensure system compatibility. While rpm is the primary tool for such tasks on systems that use RPM packages, like Red Hat Enterprise Linux (RHEL), CentOS, and Fedora, it’s also important to recognize how other package managers like apt, dnf, and zypper interface with RPM systems where applicable. The rpm command with the -qa option is an invaluable tool for listing all installed RPM packages on your system. This command is simple, direct, and outputs every package installed on your system.

For many developers and system administrators who frequently use Python command-line tools, managing dependencies and avoiding conflicts can be a hassle. This is where pipx (Python isolated Pip eXecutables) shines as a utility. It allows you to install and run Python CLI tools in isolated environments, simplifying both their execution and management. In this blog, we’ll explore what pipx is, why it might be a valuable tool for you, and how to install it using various package managers like apt, dnf, and zypper. pipx is a tool that installs and runs Python applications in isolated environments.

In the ever-evolving realm of Linux, ensuring that your system runs smoothly often involves managing packages efficiently. Occasionally, you may encounter a scenario where a package does not function as expected due to corruption, incomplete installation, or other issues. In such cases, forcing a reinstallation of the package can resolve the problem. This process can vary slightly depending on which package manager your system utilizes. In this blog post, I will guide you through the steps to force a reinstallation of packages using three popular package managers: apt for Debian-based systems, dnf for Fedora systems, and zypper for openSUSE systems. 1.

In the realm of system administration, ensuring that your server is secure is paramount. For RHEL (Red Hat Enterprise Linux) and its derivatives (including CentOS and Fedora), managing security patches effectively is crucial to shielding the system from vulnerabilities. While RHEL typically uses the yum or the newest dnf package manager, understanding how to handle security updates across different package managers like apt (for Debian-based systems) and zypper (for SUSE Linux systems) can also prove beneficial. This article will guide you through the necessary steps to identify and apply security updates using various package management tools.
