Hey all !!! ✨ Jubilant to share my day 1 of #DevOpsChallenge in a Linux Environment, and this challenge comprises the following : 📍 File system management 📍Secure user and permissions 📍Disk Usage Monitoring 📍Auditing system through file change tracking The descriptions of each command used: ✒️ ls -laht ~: Lists all files (including hidden) in the home directory, sorted by modified time. 📒 mkdir devops_challenge_day1: Creates a new working directory. 🧭 cd devops_challenge_day1: Navigates into the new directory. 📂 touch day1.txt: Creates an empty file for the challenge. 👩‍💻 du -sh /var/log: Fails due to permission error when checking log size. 📝 sudo du -sh /var/log: Succeeds in showing disk usage of /var/log. 📑 sudo adduser devops_user: Creates a new user with a home directory and sets the password. 👩‍💻 sudo usermod -aG sudo devops_user: Grants sudo (admin) privileges to the user. 📝 groups devops_user: Confirms user group membership. ✒️ chmod 600 day1.txt: Restricts file access to only the owner. ✍ ls -l day1.txt: Verifies secure permissions -rw-------. 📑 find /etc -type f -mtime -7: Finds files in /etc modified in the last 7 days. NOTE: Some permission denied errors occur as expected for protected system folders. This POC was invaluable and beginner-friendly. in this PoC, I practiced real-world DevOps scenarios using Linux command-line tools to simulate system setup and troubleshooting. #handsonDevOps #DevOpsChallenge 💪
