Introduction to Package Management in Linux

Package management is a critical aspect of Linux system administration, allowing users to easily install, update, and remove software packages. In this tutorial, we'll provide an overview of package management in Linux, covering package managers, package repositories, and common package management commands.

1. Package Managers

Linux distributions typically come with a package manager to handle software installation and maintenance. Common package managers include:

• apt: Package manager for Debian-based distributions like Ubuntu.
• yum/dnf: Package manager for Red Hat-based distributions like CentOS and Fedora.

sudo apt update           # Update package lists
sudo apt install package  # Install a package
sudo apt remove package   # Remove a package
sudo apt upgrade          # Upgrade installed packages
sudo apt search keyword   # Search for packages
