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.
■ New in 2.0: 1,510 commands, 120 flows
A big expansion focused on Windows, PowerShell and Linux (RHEL and Ubuntu). Command explanations and troubleshooting flows are now available in 9 languages.
■ Fully offline
Every command lives 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.
■ 120 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. Plain sentences like "how to check disk space" bring up the matching flow and commands. 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.
