Unix/Linux CLI Commands vs CmdDeck

Unix/Linux CLI Commands is a clean, fast reference for the Unix and Linux command line — and a safe place to practice what you learn. Whether you're a student, a developer, or a system administrator brushing up, every command is explained in plain language with real examples you can try right away. BROWSE BY CATEGORY Commands are grouped into clear categories — file management, searching, text processing, networking & communication, storage, system status and more — so you can find what you need fast or explore a topic from the ground up. LEARN WHAT EACH COMMAND DOES Each entry gives you the command, its full name, a short description of what it does, and practical examples. No fluff, no wall of man-page text — just what you need to understand and use it. PRACTICE IN A SAFE TERMINAL Reading is one thing; doing is another. The built-in terminal is a real, in-memory shell where you can actually run commands — ls, cd, pwd, mkdir, cat, echo, file, find and more — against a virtual filesystem stocked with sample files and folders. Nothing touches your real device, so you can experiment freely and break things without worry. READABLE, YOUR WAY Pick the reading font and size that suit you, and choose Light, Dark, or System appearance. Designed to look right on both iPhone and iPad. A handy companion for anyone learning the shell or keeping the essentials close at hand.

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. ■ What's inside · 882 commands across 15 platforms Linux 178, Windows 107, PowerShell 89, Kubernetes 53, macOS 52, Git 52, Cisco 48, Cloud 48, SQL 44, Docker 41, Active Directory 40, Microsoft 365 36, Virtualization 36, FortiGate 31, Yamaha 27 · 75 troubleshooting flows · Worked examples and syntax for every command · Destructive commands clearly flagged ■ Premium (one-time purchase) · All 75 troubleshooting flows (2 free) · Unlimited favorites (10 free) · iCloud sync · Personal notes on any command · Export Not a subscription.
