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're new to the command-line world. Perhaps you're just a little rusty or can't always recall the arguments for commands like lsof, or tar?

It certainly doesn't help that, in the past, the first option explained in man tar was:

$ man tar
...
-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 is room for simpler help pages focused on practical examples. How about:

<source media="(prefers-color-scheme: dark)" srcset="https://github.com/tldr-pages/tldr/blob/main/images/tldr-dark.png">
<source media="(prefers-color-scheme: light)" srcset="https://github.com/tldr-pages/tldr/blob/main/images/tldr-light.png">
<img alt="Screenshot of the tldr client displaying the tar command." src="https://github.com/tldr-pages/tldr/blob/main/images/tldr-dark.png">

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

How do I use it?

[!TIP] For browsing without installing a client on your computer, see the web client at https://tldr.inbrowser.app (with offline support using PWA).

A popular and convenient way to access these pages on your computer is to install the official Node.js client:

npm install -g tldr

Alternatively, you can also use the official Python client, which can be installed via pip3 (or other package managers):

pip3 install tldr

Linux and Mac users can also install the official Rust Client using Homebrew (or other package managers on other operating systems):

brew install tlrc

Then you have direct access to simplified, easy-to-read help for commands, such as tar, accessible through typing tldr tar instead of the standard man tar.

If you don't want to install any software, check out the PDF version instead.

[!NOTE] PDFs for translations are available for most languages. You can find them in the release assets of the latest release.

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.
