Linux › Module 2 › Lesson 4
Lab — Terminal Practice
Hands-on lab: build a mini project folder from the command line
Opening
Your first Linux project folder
Reading commands is not enough. In this lab you will create a small folder structure, copy files, and read them back—exactly like setting up a lab workspace before a CTF.
1. What You Need
Environment
Ubuntu, Kali, or WSL terminal—any Linux shell works.
Time
About 15–20 minutes. Go slow; accuracy beats speed.
2. Lab Steps
1. Check where you are: pwd 2. Create a project folder and enter it: mkdir -p ~/cyberlium-lab/module2 cd ~/cyberlium-lab/module2 3. Create a notes file with a one-line message: echo "Linux lab started" > notes.txt 4. Verify with cat: cat notes.txt 5. Copy it as a backup: cp notes.txt notes-backup.txt ls -l 6. Make a subfolder and move the backup: mkdir archive mv notes-backup.txt archive/ ls archive/ 7. Practice navigation: cd .. ls -la module2/
If something fails
Read the error message—it usually tells you the problem (permission denied, file exists, no such file). Use ls to see what is actually there before running rm.
Complete the Terminal Practice Lab
Finish all 7 steps above in your own terminal. You should end with ~/cyberlium-lab/module2/ containing notes.txt and an archive/ folder with notes-backup.txt.
