# `uniqtoo`

A single binary replicating the behavior of `sort | uniq -c | sort -nr` with output that updates
in real-time as each line is parsed.


## Usage

Pipe something line-based into `uniqtoo` the same as you would into `sort | uniq -c`.

Here is an example counting the extensions of files in this repository with a 0.5s delay in between.

You can also supply the input as a file or file descriptor as an argument.

```
$ uniqtoo input.txt
```
