The course then guides you through software installation, X Window system configuration (Red Hat specific), and navigating graphical desktop environments like Cinnamon, covering login/logout procedures, managing applications, notifications, and file management with Nemo. A significant focus is placed on the Linux terminal, teaching why it's crucial, how to execute commands, navigate the file system, manage files, and use text editors like Nano. You'll explore file searching, basic scripting with the `watch` command, and comprehensive user and group management, including creating users, changing passwords, revoking access, and understanding `sudo` for administrative privileges. Permissions are covered extensively, detailing file and directory permissions and their modification. Storage management includes mounting/unmounting volumes, automatic boot-time mounting, and analyzing disk space. Package management is taught through Linux Mint examples, covering application installation (e.g., Filezilla), configuring software sources, advanced package management techniques, and system updates. Security topics include choosing strong passwords, encrypting home folders, configuring `iptables` firewalls, and data protection strategies like backups, restores, and snapshots. Finally, you'll delve into command creation, aliases, process management (killing processes), preparing for new releases, using backup/restore tools, and monitoring resource usage, setting a strong base for advanced administration.

Red Hat Linux 9 Install Configure Administer

This dedicated section focuses intensely on Red Hat Linux 9, starting with its introduction, download process, and detailed theoretical and practical installation guides, including the initial Gnome setup. You'll become familiar with introductory terms and opening shell prompts. User creation is covered practically, followed by a deep dive into the Gnome 3 desktop environment, understanding the Gnome Shell concept, and switching between Gnome versions. Critical system configurations such as setting date and time via both GUI and command line, distinguishing between hardware and system clocks, and managing system locale settings through terminal commands are thoroughly explained. The course then moves into advanced user and group management, utilizing user setting tools, listing directories, adding new groups, creating group-specific directories, and understanding `umask` for new file permissions. Customizing the Linux environment is a key focus, covering default appearance, color highlights, updating configuration files, creating Plymouth themes, and personalizing the login screen. You'll learn to install and use `Dconf Editor` for defining desktop settings, adding greeter logos, displaying text banners, customizing desktop backgrounds, and configuring fonts with specialized tools. Further topics include Gnome desktop features, account management (allowing/disallowing access), useful shortcuts like `Ctrl+Alt+Backspace`, command-line access, virtual terminals, preventing system suspension, and in-depth user session management. A crucial module covers the Red Hat Subscription Manager, its commands, GUI/CLI registration, offline registration, and the process of unregistering/reregistering systems. Virtualization is introduced with setting up the KVM Hypervisor. The section also provides an essential introduction to Cockpit, explaining its setup, primary server configuration, and operational mechanics. Finally, it reinforces core Linux commands with practical examples of `ls`, `dir`, `pwd`, creating shell scripts, using `touch` for file creation, `cd` for directory navigation, `cat` for file display, commands for disk space analysis, the `find` command for locating files (including empty ones), and the powerful `grep` command for text searching, concluding with a summary of fundamental Linux command usage.
