Richard Blum - Mastering Linux System Administration

Use automated Red Hat package managers. Most Red Hat–based Linux distributions are based on the rpm utility but use different front‐end tools at the command line. Red Hat, CentOS, and Fedora use dnf for installing and managing software packages. The dnf tool automatically installs any software packages required by the package you install.Master It The perf utility allows you to monitor the performance of a Linux system. What command would you use to check whether the perf software is available as an rpm package for your Linux system, and what command would you use to install it? What command would you use to remove it?

Manually install Red Hat packages. Not all Linux systems are connected to the Internet, allowing the automated package management tools to connect to a repository. In those situations, you'll need to manually find and download RPM software packages and then use the rpm command to manually install the package. The most common options used to install software are the ‐Uvh options, which will update the package if it's already installed and provide verbose information on the installation progress.Master It What steps would you need to take to install the perf utility if your Linux system is not connected to the Internet?

Install flatpak application containers. Application containers are relatively new in software package management. Containers bundle all of the software required for an application to run, including all files the application is dependent on. This makes containers portable and easily moved between systems. Red Hat Linux–based distributions use the flatpak container format.Master It Cointop is a terminal‐based application for tracking cryptocurrencies. What command would you use to check if there's a flatpak container for it, and what command would you use to install it?
