WSL / Ubuntu Exercise — "My First Project"

Goal: Create a project folder, add files, edit them, and explore.

Time: ~10 minutes

---

Step 1 — Create a folder and go inside

mkdir my-project
cd my-project

Step 2 — Create a file with some text

echo "Hello from WSL!" > hello.txt

Now look at what's in the folder:

ls

Step 3 — View the file

cat hello.txt

Step 4 — Edit the file

nano hello.txt

Inside nano:

• Add a new line (e.g. Today I am learning Linux commands.)
• Save: Ctrl + O, then Enter
• Exit: Ctrl + X

Step 5 — See your changes

cat hello.txt

Step 6 — Create a backup folder and copy the file

mkdir backup
cp hello.txt backup/
ls backup/

Step 7 — List everything in detail

ls -la

Notice the file sizes, dates, and permissions.

Step 8 — Clean up (go back home)

cd ~
