Day 15 – Command Line Essentials for Developers

Hey folks

Today at Cudose Creative Agency, we stepped away from the browser and dove into something every developer should know — the Command Line (CLI).

It’s one of those superpowers that makes you faster, sharper, and more efficient.

---What We Covered

1. Basic Navigation

We learned to move around directories using commands like:

cd # change directory

ls # list files

pwd # print working directory

2. File Management

Creating, renaming, and deleting files/folders without touching the mouse:

touch index.html # create file

mkdir css # make a folder

rm -r test # remove folder

3. Chaining & Shortcuts

Running multiple commands at once and using &&, clear, and history navigation (↑ ↓ arrows).

4. Why It Matters for Devs

From running build tools (npm, git, etc.) to managing projects quickly, the CLI saves time and gives control that GUIs can’t.

---Key Takeaways:

CLI is faster than GUI once you master it

Every developer should know navigation, file ops, and shortcuts

The CLI is the foundation for Git, Node.js, and all serious dev workflows

---Final Thoughts:

Today’s class made me feel smatter, like some grandmaster of hacking, lol. The command line may look intimidating at first, but once you start using it, you’ll feel unstoppable, maybe.
