About this app

An offline reference for the Linux terminal: 360 commands, each with a colour-coded breakdown, a plain-English explanation, and an example you can copy and run.

No sign-up. No internet needed. Open it, find the command, get back to work.

━━━━━━━━━━━━━━━━━━━━━━
WHY NOT JUST GOOGLE IT
━━━━━━━━━━━━━━━━━━━━━━
Because man pages assume you already know the answer, and blog posts bury it under six paragraphs. Every entry is written for the moment you are sitting at a prompt and need the right flag now.

• FILL IN THE BLANKS — open a command's own screen, type your filename, host or port into the gaps, and copy something ready to run.
• SEARCH THAT RANKS — type "ls" and you get ls, not every description containing those two letters. Search by what a command used to be called (ifconfig finds ip addr) or in plain English: "delete a file", "how much ram".
• SYNTAX HIGHLIGHTING — coloured by part, so you can see which piece is the flag and which you must replace.
• RUN IT IN TERMUX — send the finished command straight to Termux instead of retyping it.
• LEARN TAB — twelve short pieces on how the shell actually works: pipes and redirection, globbing, what 755 means, exit codes, signals, quoting, cron, PATH. Plus practice cards that resurface a command until it sticks.
• NOTES AND COLLECTIONS — write a note on any command, group commands into named collections, and export the lot so a new phone is not a fresh start.
• FAVOURITES AND ONE-TAP COPY — star what you keep forgetting; copy the command alone or the whole entry.
• HOME SCREEN WIDGET — a new command every day. Long-press the icon for shortcuts to search or favourites.
• DARK AND LIGHT THEME — a real light theme, properly contrast-checked.
• COMPLETELY OFFLINE — the database ships inside the app. It works on a plane, in a server room, anywhere with no signal.

WHO IT IS FOR
━━━━━━━━━━━━━━━━━━━━━━
• Beginners meeting the command line for the first time
• Students and self-taught developers who want a cheat sheet that explains itself
• Sysadmins and DevOps engineers chasing a flag they half-remember
• Anyone revising for a Linux interview or exam
• Termux users who want the reference on the device they are typing on

These are the standard commands, so they apply across Ubuntu, Debian, Mint, Fedora, RHEL, Arch, openSUSE, Alpine and Kali, and on WSL, Raspberry Pi OS and Termux.

━━━━━━━━━━━━━━━━━━━━━━
BUILT PROPERLY
━━━━━━━━━━━━━━━━━━━━━━
Kotlin and Jetpack Compose with Material 3. Your favourites, notes and collections stay on your device, not on a server.

Found a mistake? Every card has a "report a problem" link straight to the developer. Reports get read.

Ratings and reviews

I'm just going to review that this is a MADD App and that it should also have a way to work on my Xbox Series S Console somehow LoL. Thankyou for Making this App! I'm impressed!

This is the best app for the Linux OS. I recommend everyone, to download the app especially those who are studying computer science and Information Technology.

Why unix machine command line don't have built in AI.

What’s new

You can now add your own commands.

Write a command you keep forgetting, give it a title, and it lands alongside the built-in ones: searchable, favouritable, and ready for collections and practice. Put anything you will want to change in square brackets and the app will fill it in for you later.

Four new topics in Learn: command substitution, text-processing pipelines, shell history, and package managers compared across Debian, Fedora, Arch and Alpine.
