Top Basic Linux Commands used in daily life in Linux Administrations

CLI commands, or Command-Line Interface commands, are instructions given to a computer operating system or application through a text-based interface. They allow users to interact with the system, perform tasks, configure settings, and execute programs or scripts directly from the command line.

Here's a short description of the benefits and uses of CLI commands:

1. Flexibility and Control: CLI commands provide granular control over the system, allowing users to perform specific actions and configure settings precisely.

2. Automation: CLI commands are scriptable, enabling users to automate repetitive tasks by writing scripts that execute a series of commands in a sequence.

3. Remote Access: CLI commands are commonly used for remote system administration, allowing administrators to manage systems over a network connection without requiring a graphical user interface.

4. Efficiency: CLI commands often provide quicker and more efficient ways to perform tasks compared to navigating through graphical interfaces. They are especially useful for experienced users who are comfortable with the command-line environment.

5. Scripting and Programming: CLI commands can be used within scripts and programs, allowing developers to create complex automation workflows and build customized solutions.

6. Server Administration: CLI commands are extensively used in server administration for tasks such as managing users and permissions, configuring network settings, monitoring system resources, and deploying applications.

7. Troubleshooting and Diagnostics: CLI commands provide powerful tools for diagnosing and troubleshooting issues. They can help gather system information, analyze logs, and perform debugging tasks.
