Navigating different Linux families requires knowing the right "language." Here is a quick-start guide for the most common tasks:
| Task | Ubuntu/Debian (APT) | RHEL/CentOS/Rocky (DNF) | Arch Linux (Pacman) |
| Update Repos | sudo apt update | sudo dnf check-update | sudo pacman -Sy |
| Install Package | sudo apt install [pkg] | sudo dnf install [pkg] | sudo pacman -S [pkg] |
| Remove Package | sudo apt remove [pkg] | sudo dnf remove [pkg] | sudo pacman -R [pkg] |
| Check Services | systemctl status [svc] | systemctl status [svc] | systemctl status [svc] |
Permission Denied: Use ls -l to check ownership. Fix with sudo chown user:group [file] or chmod 644 [file].
Service Won't Start: Always check the journal first: journalctl -u [service_name] -xe.
High Load: Use top or htop. Look for processes in the "D" state (Uninterruptible sleep), which usually indicates I/O wait issues.
To resolve complex issues, I utilize the industry-standard "Power Tools":
Networking:nmap, tcpdump, dig, and iproute2 for traffic analysis.
Performance:iostat, vmstat, netstat, and sar (sysstat).
Debugging:strace (to see system calls) and gdb (for application crashes).
Security:Lynis for security auditing and Fail2Ban for intrusion prevention.
Documentation is King: Always maintain a "runbook" of every custom change made to the default installation.
Separate Partitions: Never put /home, /var, and / on the same partition. If logs fill up /var, your system won't crash.
SSH Best Practices: Disable root login, change the default port, and only use SSH Key authentication.
Test Backups: A backup is only a "hope" until you have successfully performed a restoration test. I validate recovery procedures monthly.
