Welcome back to our DevOps journey! Today, we'll explore some basic Linux commands that are essential for every DevOps engineer. 🚀

Let's dive in and discover these commands with a touch of fun and excitement! 🎉

1️⃣ Viewing File Content 👀

To satisfy your curiosity and view what's written in a file, you can use the cat command. It's like peeking into a treasure chest! 💎

$chmod 755 myfile.sh

3️⃣ Checking Command History ⏳

Ever wondered how many commands you've conquered on your DevOps journey? The history command reveals your past triumphs! ⚔️

4️⃣ Removing a Directory 🗂️

When it's time to bid farewell to a directory or folder, the rm command comes to the rescue! 🚫

5️⃣ Creating and Viewing a File 📄

To create a file full of fruity goodness, use the touch command, like planting a seed. Then, use cat to view the vibrant content of the file! 🍎🍌🍒

cat fruits.txt

6️⃣ Adding Content to a File 🖋️

Get your virtual paintbrush ready! Use the echo command followed by the redirection symbol (>>) to add colorful fruits to the "devops.txt" file. Each fruit on a new line, like a painter's strokes! 🎨

Example:

$echo "Apple" >> devops.txt
$echo "Mango" >> devops.txt
$echo "Banana" >> devops.txt
