🚀 Commands & Troubleshooting

Navigating different distributions requires knowing the right "handshake" for each package manager.

1. Essential Commands by Distribution

Task	Ubuntu/Debian (apt)	RHEL/Alma/Rocky (dnf)	Arch Linux (pacman)
Update System	`sudo apt update && upgrade`	`sudo dnf upgrade`	`sudo pacman -Syu`
Install Package	`sudo apt install [pkg]`	`sudo dnf install [pkg]`	`sudo pacman -S [pkg]`
Check Services	`systemctl status [svc]`	`systemctl status [svc]`	`systemctl status [svc]`

2. Fixing Common Issues

Permission Denied: Always check ls -l and use chmod or chown. If a script won't run, try chmod +x script.sh.
Full Disk: Use du -sh * to find space hogs and journalctl --vacuum-time=2d to clear old logs.
Network Down: Check the interface with ip a and test connectivity with nmcli or ping.

🧰 The Linux Expert’s Toolkit

To resolve issues with surgical precision, I utilize:

Performance: top, htop, iotop, and glances.
Networking: nmap, tcpdump, netstat, and dig.
Log Analysis: tail -f /var/log/syslog, grep, and awk.
Automation: Ansible for configuration and Python for custom tooling.

💡 Tips for a Successful Server Setup

Use SSH Keys Only: Disable password-based logins immediately to prevent brute-force attacks.
Separate Partitions: Keep /home, /var, and / on separate partitions to prevent log files from crashing the OS.
Document Everything: Maintain an operational runbook. If it isn't documented, it didn't happen.
Automate Early: Use Docker for application environments to ensure consistency across dev and production.
