# Linux Essentials — Detailed Lab Overview
|
||
|
||
## Duration
|
||
**3 Hours (12 Steps)**
|
||
|
||
## Audience
|
||
This lab is designed for **complete beginners** (equivalent to 10th grade students) who are learning Linux and the terminal for the first time.
|
||
No prior Linux knowledge is assumed. Each instruction is step-by-step and written in simple language.
|
||
|
||
## Lab Format
|
||
- **Instruction Lab**: You will be guided through commands and concepts directly.
|
||
- **Hands-On Practice**: You will type commands into the terminal and observe outputs.
|
||
- **Validation Tasks**: At the end, optional tasks (Git & Networking) include helper files and validation scripts.
|
||
|
||
## Learning Objectives
|
||
By the end of this lab, you will be able to:
|
||
1. Open and use the Linux terminal effectively.
|
||
2. Navigate the filesystem and perform file operations.
|
||
3. View, search, and filter text files.
|
||
4. Manage processes and jobs (foreground/background).
|
||
5. Understand file permissions and change them with `chmod` and `chown`.
|
||
6. Gather system information (disk, memory, uptime).
|
||
7. Perform basic networking commands (ping, DNS lookups, open ports).
|
||
8. Archive and compress files using `tar` and `gzip`.
|
||
9. Use the package manager (`apt`) to install and remove software.
|
||
10. Write and run simple shell scripts.
|
||
11. Permissions Challenge.
|
||
12. Troubleshoot connectivity and DNS resolution.
|
||
|
||
## Structure
|
||
- **Steps 1–10**: Core Linux skills (approx. 200 minutes).
|
||
- **Steps 11–12**: Validation tasks with helpers (approx. 30 minutes).
|
||
- Each step is **10 minutes** on average, but you may take longer as you practice.
|
||
|
||
## Requirements
|
||
- **Operating System**: Ubuntu 24 (or similar Linux distribution).
|
||
- **Tools**: Terminal application (bash shell).
|
||
- **Network**: Internet connection for package installation and DNS tests.
|
||
- **Permissions**: Some tasks require `sudo` access (administrator rights).
|
||
|
||
## Key Skills Practiced
|
||
- Working with the Linux command line
|
||
- Creating and organizing files and directories
|
||
- Redirecting and searching text output
|
||
- Managing processes and monitoring system usage
|
||
- Adjusting permissions for files and directories
|
||
- Compressing and archiving data
|
||
- Installing/removing software with APT
|
||
- Writing and running bash scripts
|
||
- Using Git for version control
|
||
- Troubleshooting basic networking issues
|
||
|
||
## Suggested Workflow
|
||
1. **Follow each step in order.** Each builds on the previous one.
|
||
2. **Type commands manually.** Avoid copy-paste to build muscle memory.
|
||
3. **Observe the output carefully.** Compare it with expected results.
|
||
4. **Repeat tasks** if something doesn’t work — troubleshooting is part of learning.
|
||
5. **Try variations** (e.g., different filenames, directories) to deepen your understanding.
|
||
|
||
## Completion Criteria
|
||
- You have successfully completed all 10 instructional steps.
|
||
- You optionally attempted Steps 11 and 12 and passed the provided validation scripts.
|
||
- You are comfortable using the Linux terminal for basic daily tasks.
