📚 Collaborative cheatsheets for console commands

What is tldr-pages?

The tldr-pages project is a collection of community-maintained help pages for command-line tools, that aims to be a simpler, more approachable complement to traditional man pages.

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?

It certainly doesn't help that the first option explained in man tar is:

-b blocksize
   Specify the block size, in 512-byte records, for tape drive I/O.
   As a rule, this argument is only needed when reading from or writing to tape drives,
   and usually not even then as the default block size of 20 records (10240 bytes) is very common.

There seems to be room for simpler help pages, focused on practical examples. How about:

This repository is just that: an ever-growing collection of examples for the most common UNIX, Linux, macOS, SunOS, and Windows command-line tools.

How do I use it?

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:

npm install -g tldr

You can also use the fully-featured official Python client which can be installed via pip3.

pip3 install tldr

That way you can write tldr tar in the terminal to show the tldr page for tar, just like you would write man tar to show its manpage.

However, if you just want to browse without installing anything, check out the PDF version.

There are also various other clients provided by the community, both for the command-line and for other platforms. For a comprehensive list of clients, head over to our Wiki.

What does "tldr" mean?

TL;DR stands for "Too Long; Didn't Read". It originated as Internet slang, where it is used to indicate that a long text (or parts of it) has been skipped as too lengthy. Read more in How-To Geek's article.
