Because typing the same command twice is a crime.
Welcome to fx5 Wiki – a curated collection of snippets, commands, configs, and notes for people who like terminals more than GUIs and logs more than vibes.
This wiki is built for computer enthusiasts, admins, engineers, and curious nerds who want practical solutions without fluff.
This is not a tutorial site.
This is a working knowledge base.
- ✅ short, reusable snippets
- ✅ real-world configs
- ✅ things you forget until you need them at 02:00
- ❌ no marketing
- ❌ no “Hello World”
- PowerShell one-liners
- Services, registry, networking
- AD, permissions, automation
- Debugging weird Windows behavior
- Bash & shell snippets
- systemd, journald, cron
- Networking, firewalling
- Docker, containers, troubleshooting
- FortiGate (CLI, policies, VPNs)
- Routing, NAT, VLANs
- Packet flow & diagnostics
- “Why does this not pass traffic?”
- Git tricks
- CI/CD notes
- API testing
- Logs, metrics, sanity checks
- Regex that actually works
- Encoding, decoding, formats
- File formats, protocols
- Stuff Future-You will thank Past-You for
Every page should ideally answer one clear question, for example:
- How do I…
- Why does this fail…
- What is the minimal working config for…
If a snippet:
- saved time → it belongs here
- prevented a mistake → it belongs here
- required googling twice → it definitely belongs here
- Be concise
- Show commands as-is (no magic)
- Add context only where needed
- Prefer copy-paste-ready examples
Bad:
# run this command
Good:
# Restart systemd-networkd and verify status
systemctl restart systemd-networkd
systemctl status systemd-networkd
This wiki grows by:
- adding new snippets
- improving existing ones
- correcting outdated information
If something breaks after an update, document it.
If something is ugly but works, keep it.
Commands here are:
- tested somewhere
- not always safe everywhere
You run them at your own risk.
(But honestly, you knew that already.)
