Why Learn Linux File System and Shell Scripting?

Linux is widely used in production environments, and knowing how to navigate and automate tasks gives you a strong advantage.

Key Benefits:

• Efficient file management
• Better system control
• Automation of repetitive tasks
• Improved productivity

These skills are essential for developers, DevOps engineers, and system administrators.

Understanding the Linux File System

The Linux file system organizes how data is stored and accessed.

Key Features:

• Hierarchical structure (tree-like)
• Everything is treated as a file
• Organized directories

Important Directories

/ (Root Directory)

The top-level directory in Linux.

/home

Stores user files and personal data.

/etc

Contains system configuration files.

/var

Stores logs and variable data.

/bin and /usr/bin

Contain essential system commands.

Understanding these directories helps you navigate Linux systems effectively.

File and Directory Management

Managing files is a daily task in Linux.

Common Commands:

• ls – List files
• cd – Change directory
• pwd – Show current path
• mkdir – Create directories
• rm – Delete files

File Operations:

• Copy files using cp
• Move files using mv
• Rename files

These operations are essential for system management.

File Permissions and Ownership

Linux provides strong security through permissions.

Types of Permissions:

• Read (r)
• Write (w)
• Execute (x)

Commands:

• chmod – Change permissions
• chown – Change ownership

Proper permission management ensures system security.

Introduction to Shell Scripting

Shell scripting allows you to automate tasks using scripts.

What is a Shell Script?

A shell script is a file containing a series of commands executed by the shell.

Why Use Shell Scripting?

• Automate repetitive tasks
• Save time

Writing Your First Shell Script

Creating a basic script is simple.

Example;

Steps:

1. Create a file
2. Add commands
3. Make it executable
4. Run the script

This is the foundation of automation.

Variables in Shell Scripting

Variables store values in scripts.

Example;

Variables make scripts dynamic and flexible.

Control Statements in Shell Scripts

Control statements help manage the flow of scripts.

If Statement:

Loops:

These structures help automate complex tasks.

Working with Files in Scripts

Shell scripts can interact with files.

Tasks:

• Read file content
• Write data to files
