Subject: Computer Science
Topic: Command Line
Duration: 30 minutes
Grade: 11 (Age 16-18)

---

Lesson Objectives

By the end of this lesson, students will be able to:

• Understand the purpose and significance of the command line interface (CLI).
• Navigate and use basic commands in the command line.
• Create, delete, and manipulate files and directories.

---

Materials Needed

• Computers with a command line interface (Windows Command Prompt, Mac Terminal, or Linux Shell).
• Projector for demonstration.
• Handouts with command line commands and exercises.

---

Lesson Outline

Introduction (5 minutes)

• Begin with a brief discussion about what a command line interface is.
• Explain the differences between a graphical user interface (GUI) and a CLI.
• Emphasize the relevance of CLI in various fields such as programming, system administration, and application development.

Command Line Basics (10 minutes)

What is a Command Line?

The command line allows users to interact with the operating system by typing text commands. It is a powerful tool that offers more control and efficiency.

Navigating the Command Line

• Opening the Command Line

  • Windows: Press Win + R, type cmd, and hit Enter.
  • Mac: Use Spotlight (Cmd + Space), type Terminal, and hit Enter.

• Basic Commands

  • pwd (Print Working Directory): Shows the current directory.
  • ls (List): Lists files and directories in the current location (use dir for Windows).
  • cd (Change Directory): Moves between directories.
    • Example: cd Documents

File Manipulation Commands

• Creating a File

  • touch filename.txt (Mac/Linux)
  • echo. > filename.txt (Windows)

• Deleting a File

  • rm filename.txt (Mac/Linux)
  • del filename.txt (Windows)

• Creating a Directory

  • mkdir new_directory

• Removing a Directory

  • rmdir new_directory (make sure it's empty)

Class Activity (10 minutes)

Hands-on Exercise

1. Navigate to Your Home Directory

   • Use the cd command to move to your home directory.

2. Create a New Directory

   • Create a directory named test_directory.

3. Create a File Inside the Directory

   • Navigate into test_directory and create a file named file1.txt.

4. List Files

   • Use ls or dir to check that file1.txt exists.

5. Delete the File and Directory

   • Delete the file and then remove the directory.

Instructors should circulate to assist students as they complete these tasks.

Wrap-Up and Q&A (5 minutes)

• Recap main points of the lesson.

• Engage students with a few questions:

  • Why might someone prefer using the command line over a GUI?
  • Can you think of scenarios where command line skills might be essential?

• Encourage students to explore more commands and practice on their own.

Assignment (Optional)

Assign students to research and document three advanced command line commands they find interesting. They should prepare to share their findings in the next class.

Conclusion

This lesson provides an essential foundation for students to explore the command line further, enhancing their computing skills and understanding of operating systems. Encourage curiosity and experimentation beyond the classroom!
