In this video we share some basic command that are used in Linux
Redhat Enterprise Linux 9 (RHEL9) is a popular operating system used by many organizations and individuals for their server and desktop computing needs. Whether you are a beginner or an experienced user, understanding the basic commands of Redhat RHEL9 Linux is crucial for efficient system administration. In this article, we will introduce you to some of the essential commands of Redhat RHEL9 Linux, including shell, GUI, CLI, date, cal, bash, and GNOME.
Shell
The shell is a command-line interface that allows users to interact with the operating system by typing commands. RHEL9 Linux comes with different shells, including Bash (Bourne-again shell), Korn shell, and C shell. By default, RHEL9 uses the Bash shell, which is the most popular and widely used shell in Linux. The shell provides a powerful way to execute commands, manage files, and automate tasks.
GUI
The Graphical User Interface (GUI) is a graphical interface that allows users to interact with the operating system using icons, buttons, and menus. In RHEL9 Linux, GNOME is the default GUI that provides an intuitive and user-friendly interface. GNOME allows users to perform common tasks like browsing the web, checking emails, and managing files using a mouse and keyboard.
CLI
The Command-Line Interface (CLI) is a text-based interface that allows users to interact with the operating system using commands. Unlike the GUI, the CLI requires users to type commands in the terminal to execute tasks. In RHEL9 Linux, the CLI is powerful and versatile, providing users with access to advanced system administration tools and automation.
Date
The date command is used to display or set the system date and time. By default, RHEL9 Linux sets the system date and time based on the timezone configured during installation. The date command is useful when scheduling tasks, generating timestamps, and troubleshooting time-related issues.
Cal
The cal command is used to display a calendar of a specific month or year. The command can be used to display the current month, a specific month, or a whole year. The cal command is useful when scheduling tasks or checking dates.
Bash
Bash (Bourne-again shell) is a powerful and versatile shell that provides users with advanced features like command history, command substitution, and variable expansion. Bash is the default shell in RHEL9 Linux and is widely used by developers, system administrators, and power users.
GNOME
GNOME is the default GUI in RHEL9 Linux and provides users with an intuitive and user-friendly interface. GNOME allows users to perform common tasks like browsing the web, checking emails, and managing files using a mouse and keyboard. GNOME also provides a wide range of customization options, allowing users to tailor the interface to their preferences.
In conclusion, understanding the basic commands of Redhat RHEL9 Linux is crucial for efficient system administration. The shell, GUI, CLI, date, cal, bash, and GNOME are essential components of RHEL9 Linux that provide users with advanced features and tools to manage their system effectively. Whether you are a beginner or an experienced user, mastering these commands will help you become a proficient RHEL9 Linux user.
