## 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](https://en.wikipedia.org/wiki/Man_page).

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:

```console
$ 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:

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