CmdDeck: Linux & CLI Commands

The fastest way to get from a symptom to the command that fixes it.

Type "cannot connect to the network" into the search box. A diagnostic flow opens with ping, ipconfig, nslookup and tracert laid out in the order you actually run them. You don't need to remember the command name.

■ Fully offline
All 882 commands live on your device. Server rooms with no signal, air-gapped networks, a customer site with the Wi-Fi down. The moments you most need to look up networking are the moments the network is broken. Nothing is transmitted, ever.

■ 75 troubleshooting flows
"PC is slow." "Mail not arriving." "Port already in use." "Clock drift." Enter the symptom and get an ordered set of steps, each with the command to run at that step. Less time guessing where the fault is.

■ Search that forgives
Type "ipconfog" and it suggests ipconfig. Search by alias, not just by name. Filter chips narrow results to Linux, Windows, Cisco and the rest in one tap.

■ Spotlight
Swipe down on your home screen, type "netstat", jump straight to the entry without opening the app.
