A collection of simplified and community-driven man pages.

Install it with `npm install -g tldr` or [try the web client](https://ostera.github.io/tldr.jsx).

## What is tldr?

New to the command-line world? Or just a little rusty?
Or perhaps you can't always remember the arguments to `lsof`, or `tar`?

Maybe it 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.
```

Surely people could benefit from simplified "show me the common usages" man pages. What about:

This repository is just that:
an ever-growing collection of examples
for the most common UNIX / Linux / OSX / SunOS commands.

## What does tldr mean?

TL;DR stands for "Too Long; Didn't Read".
It originates in Internet slang, where it is used to indicate parts of the text skipped as too lengthy.
