Linux for Beginners: Install Ubuntu + Linux Files & Folders Explained (Home Lab Part 4)

Mô tả

Welcome back! Part 4 of the Drillerbyte Cybersecurity Home Lab series is here, and this time we are deep into Section 3 of the Linux mini-course — Working With Files and Folders.

This section is where things start getting really practical. Every command in this video is something you will use on the job, whether you are in IT support, a SOC role, or doing penetration testing. By the end of this video you will be creating, copying, moving, renaming, and deleting files and directories from the terminal with confidence.

Here is exactly what we cover:
✅ touch — creating empty files, single and multiple at once
✅ echo — printing to screen and redirecting output into a file
✅ nano — terminal-based text editor for creating and editing files
✅ mkdir and mkdir -p — creating directories and nested folder structures
✅ cp and cp -r — copying files and entire directories
✅ mv — moving and renaming files
✅ rm — deleting files safely
✅ rmdir — removing empty directories
✅ rm -r — recursively removing folders and everything inside them
✅ Wildcards (*) — working with multiple files in a single command

We also do a full walkthrough of the Section 3 practice quiz at the end so you can test yourself before moving on.
