What it does
Picking the right flags for common CLI tools means constantly checking man pages or searching the web. This tool lets you select a command, tick the flags you need from a checklist (each with a short explanation), fill in any required values, and instantly get the full, ready-to-copy command — built entirely in your browser.

How it works
- Choose a base command from the dropdown (
curl,grep,tar,rsync,nmap,docker run,ffmpeg, ...). - Each command exposes a curated list of its most useful flags as checkboxes. Some flags need a value (e.g.
-o <file>,--rate <n>) — a small text input appears next to them when checked. - As you check/uncheck flags or type values, the command at the bottom rebuilds live, in the correct order (global flags, then value-flags, then your target/arguments).
- Click Copy to put the generated command straight onto your clipboard.
Notes
- This is a curated cheatsheet of the most commonly used flags per command, not an exhaustive replacement for
man <command>or<command> --help. - Everything runs in your browser — nothing is sent anywhere, and no command is ever executed; it only builds the text of a command for you to run yourself.
- Flag data lives in
commands.js, so adding a new command or flag is a simple, self-contained edit — no other file needs to change.
