Welcome to my Linux Foundations learning repository.
This repo documents my journey as I build a strong foundation in Linux for cybersecurity, penetration testing, and system administration.
The goal is not just to collect commands, but to create a structured, professional reference that demonstrates both learning progress and practical application.
Linux is at the heart of servers, cloud platforms, and cybersecurity labs.
As part of my learning path, I am:
- Documenting commands and concepts in clear, structured notes
- Practicing with interactive labs (LabEx, local VMs, HackTheBox, VulnHub)
- Writing small Bash scripts to automate tasks
- Recording my progress like a developer’s logbook
This makes the repo both a personal study resource and a portfolio for others to follow along.
