tldr-pages
Collaborative cheatsheets for console commands
...The tldr pages are a community effort to simplify the beloved man pages with practical examples. Maybe you are new to the command-line world? Or just a little rusty? Or perhaps you can't always remember the arguments to lsof, or tar? There seems to be room for simpler help pages, focused on practical examples. This repository is just that, an ever-growing collection of examples for the most common UNIX, Linux, macOS, SunOS and Windows command-line tools. A popular and convenient way to access these pages on your computer is to install the Node.js client, which is supported by the tldr-pages project maintainers.
