Regardless of your flavor of Linux, these are the commands I use daily to diagnose and manage systems:
| Task | Debian/Ubuntu | RHEL/CentOS/Rocky | Arch Linux |
| Update Repos | sudo apt update | sudo dnf check-update | sudo pacman -Sy |
| Install Package | sudo apt install | sudo dnf install | sudo pacman -S |
| Check Services | systemctl status | systemctl status | systemctl status |
| Disk Usage | df -h | df -h | df -h |
"Permission Denied": Often a result of incorrect ownership. Use ls -l to check, and chown -R user:group /path to fix.
Dependency Hell: If a package won't install, use apt --fix-broken install (Debian) or dnf distro-sync (RHEL) to align versions.
Full Disk: If a server hangs, check /var/log size. Use du -sh /* to find the culprit directory.
To resolve issues like a pro, I utilize:
htop / btop: For real-time process and resource visualization.
nmap / netstat: For network scanning and port troubleshooting.
strace: To intercept and record system calls made by a process.
tcpdump: For deep packet analysis when network issues arise.
journalctl: The centralized tool for inspecting systemd logs.
Partition Wisely: Always separate /var, /home, and / to prevent logs or user data from crashing the entire OS.
SSH Security: Disable root login and password authentication immediately; use SSH keys exclusively.
Documentation: Maintain a "Change Log" for every configuration tweak you make to ensure reproducibility.
Minimize: Only install the packages you need. A smaller footprint means a smaller attack surface.
