Introduction2:29

Understanding Command Line2:03
Basic Linux Commands3:36
Master basic Linux commands such as ls and cd, create and edit files with touch and nano, and copy, move, delete, view, and echo with cp, mv, rm, cat.
File Permissions (Basics)2:14
File Permissions (Advanced)22:04
Explore how to view and modify file permissions using symbolic notation, including owner, group, and other bits, and practice applying chmod to secure sensitive files.

Creating Your First Shell Script1:26
Create your first shell script by writing a text file of commands, using nano, to automate tasks and print hello world, then run it with bash.
Making a Shell Script Executable1:00
Understanding Shebang (#!)1:41
Explore the shebang, a two-byte magic number at the start that specifies the interpreter path. Use /bin/bash and create executable scripts, then save and run to see hello world.

Using 'echo' and 'printf' for output4:15
Explore the fundamental output commands in shell scripting. Learn how to use 'echo' for simple text display and 'printf' for formatted output.
Using 'read' for input2:39
Delve into user input in shell scripting with the 'read' command. Discover how to capture user inputs and assign them to variables for further processing.
Using 'grep', 'awk', and 'sed' for text processing4:06
Uncover powerful text processing tools in Linux. Learn how to find patterns with 'grep', manipulate text with 'awk', and perform text transformations with 'sed'.

Functions: Definition and Usage2:08
we explore functions in shell scripting, introducing how to create reusable code blocks for specific tasks, and demonstrating the usage of arguments to pass parameters into these functions.
Local and Global Variables in Functions1:35
we delve into the intricacies of variable scope within functions in shell scripting, differentiating between local variables that exist only within functions, and global variables that are accessible throughout the entire script.
Arrays: Definition and Usage3:12
we introduce the concept of arrays in shell scripting, focusing on how to define, manipulate, and access indexed and associative arrays, which provide a way to store multiple values in a single variable

File and Directory Handling Commands3:20
Learn to list, create, navigate, copy, and delete files and directories in linux bash shell scripting using ls (with -l), mkdir, cd, pwd, touch, cp, and rm.
Understanding /dev, /proc, and /sys Filesystems2:10
Explore Linux /dev, /proc, and /sys: /dev holds hardware device files, /proc provides per-process kernel information, and /sys exposes kernel data with /sys/class; browse cautiously.
Working with File Permissions3:11
Learn to view and manage Linux file permissions with ls -l, identify files and directories by type, and use mode command to grant execute rights for user, group, and others.

Requirements

Familiarity with Linux/Unix Operating Systems: Having a basic understanding of Linux/Unix operating system concepts
Basic Computer Skills: Learners should be comfortable with basic computer operations and functionalities.

Description

This two-hour course gives you a simple and friendly introduction to shell scripting, one of the most important skills for anyone working with Linux. Shell scripting means writing small programs, called scripts, that the Linux system can read and run for you. These scripts can do many tasks, such as moving files, checking system health, managing users, installing updates, and much more — all without you needing to repeat the same steps every day.

For Linux administrators, shell scripting is extremely valuable. It helps automate daily jobs, save time, reduce mistakes, and make systems run more smoothly. Instead of typing long commands again and again, you can write one script and let the system handle the work for you. This makes your job easier and makes you more efficient.

For DevOps engineers, shell scripting is an essential foundation. Many DevOps tools — like CI/CD pipelines, configuration management, and cloud deployment scripts — depend on Linux commands and shell automation. If you understand shell scripting, you can troubleshoot faster, build better pipelines, and work confidently with servers, containers, and cloud environments.

Learning shell scripting will help your career because it is a skill used in almost every company that works with Linux or DevOps. Employers look for people who can automate tasks, understand systems, and solve problems quickly. Even basic scripting knowledge can make you stand out and open the door to more advanced tools and technologies in the future.

By the end of this short course, you will understand what shell scripts are, how to write simple ones, and how they can make your daily work faster and easier.

Who this course is for:

Beginners in Linux: Individuals new to Linux administration eager to learn Bash scripting fundamentals.
Aspiring Administrators: Aspiring system administrators wanting to enhance their skill set in Bash scripting.
