### Overview (`README.md`)

# Dust

du + rust = dust. Like du but more intuitive.

# Why

Because I want an easy way to see where my disk is being used.

# Demo

Study the above demo

* We cd into a webapp it is 72K in size.

* We see 32K in the `src` folder. Note the bar jumps to 44%. Half of the webapp is in src

* We see 8K in the `src/utils`. The bar jumps down to 11% but a shadow stays at 44% showing that it is part of the `src` folder

* We then demo the -d 2 flag - Show a depth of 2 folders

* We demo the -n 5 flag - Show only 5 items (by default we show terminal height items)

## Overview

Dust is meant to give you an instant overview of which directories are using disk space without requiring sort or head. Dust will print a maximum of one 'Did not have permissions message'.

Dust will list a slightly-less-than-the-terminal-height number of the biggest subdirectories or files and will smartly recurse down the tree to find the larger ones. There is no need for a '-d' flag or a '-h' flag. The largest subdirectories will be colored.

The different colors on the bars: These represent the combined tree hierarchy & disk usage. The shades of grey are used to indicate which parent folder a subfolder belongs to. For instance, look at the above screenshot. `.steam` is a folder taking 44% of the space. From the `.steam` bar is a light grey line that goes up. All these folders are inside `.steam` so if you delete `.steam` all that stuff will be gone too.

If you are new to the tool I recommend to try tweaking the `-n` parameter. `dust -n 10`, `dust -n 50`.

## Usage

```
/* Detailed source-code truncated for AI context efficiency. */
```

## Config file

Dust has a config file where the above options can be set.
Either: `$XDG_CONFIG_HOME/dust/config.toml` (falling back to
`~/.config/dust/config.toml`) or `~/.dust.toml`
```
$ cat ~/.config/dust/config.toml
reverse=true
limit-filesystem=true
```
Keys use the long flag name in kebab-case. See [config/config.toml](config/config.toml) for a fuller sample.

## Alternatives

- [NCDU](https://dev.yorhel.nl/ncdu)
- [dutree](https://github.com/nachoparker/dutree)
- [dua](https://github.com/Byron/dua-cli/)
- [pdu](https://github.com/KSXGitHub/parallel-disk-usage)
- [dirstat-rs](https://github.com/scullionw/dirstat-rs)
- `du -d 1 -h | sort -h`

## Why to use Dust over the Alternatives

Dust simply Does The Right Thing when handling lots of small files & directories. Dust keeps the output simple by only showing large entries.

Tools like ncdu & baobab, give you a view of directory sizes but you have no idea where the largest files are. For example directory A could have a size larger than directory B, but in fact the largest file is in B and not A. Finding this out via these other tools is not trivial whereas Dust will show the large file clearly in the tree hierarchy 

Dust will not count hard links multiple times (unless you want to `-s`).

Typing `dust -n 90` will show you your 90 largest entries. `-n` is not quite like `head -n` or `tail -n`, dust is intelligent and chooses the largest entries
