🚀 Day 3 of DevOps Mastery: Unraveling the Basics of Linux Commands 🐧

Welcome back, fellow DevOps enthusiasts! Today, we're sharpening our Linux prowess by tackling essential commands that are the bread and butter of any DevOps professional's toolkit. 🛠️

What's Today's Mission? 🎯

We're going to explore commands that allow us to interact with files, view command histories, manage directories, and compare content. Ready? Let's dive in!

Peeking into Files 🔍

To view a file's content: cat filename.txt is your go-to command.
Want to check a file but it's too long? Use less filename.txt or more filename.txt to scroll through the content.

Permission Changing Ceremony 🔐

Modifying access permissions: If you're looking to change permissions, chmod is your command. Remember, it's about who gets to read (r), write (w), or execute (x).

Historic Commands Chronicles 📜

To recall your command history: Simply type history and watch your command journey unfold.

Directory Disappearance Act 🗑️

Removing directories: rmdir directoryName will make it vanish (if it's empty). For a non-empty directory, rm -r directoryName is your magic spell.

The Tale of the Fruits.txt 📝

Creating and viewing a file: touch fruits.txt creates it, and cat fruits.txt lets you peek inside.
Enlisting fruits: echo -e "Apple\nMango\nBanana\nCherry\nKiwi\nOrange\nGuava" >> fruits.txt will fill your file with fruity goodness.

The Great Fruit Reveal 🥝

Top three fruits: head -n 3 fruits.txt will showcase the fruit podium finishers.
Bottom three fruits: tail -n 3 fruits.txt reveals who's wrapping up the list.

Colors.txt: A Rainbow Creation 🌈

Crafting Colors.txt: touch Colors.txt and cat Colors.txt to create and view your colorful creation.
Coloring the file: echo -e "Red\nPink\nWhite\nBlack\nBlue\nOrange\nPurple\nGrey" >> Colors.txt adds a splash of color to your file.

A Comparative Study: Fruits vs. Colors 🍊 vs. 🎨

Spot the differences: diff fruits.txt Colors.txt will highlight what sets these files apart.

In Conclusion 🏁

Mastering these commands is a stepping stone to becoming a Linux command-line wizard. Keep practicing, and soon you'll be casting these commands with the ease of a seasoned sorcerer!
