      (an example is provided in the Appendix below).

"Derivative Works" shall mean any work, whether in Source or Object

      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,

      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

# 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

![Example](media/snap.png)

#### Cargo <a href="https://repology.org/project/du-dust/versions"><img src="https://repology.org/badge/vertical-allrepos/du-dust.svg" alt="Packaging status" align="right"></a>

- `cargo install du-dust`

#### 🍺 Homebrew (Mac OS)

- `brew install dust`

#### 🍺 Homebrew (Linux)

- `brew tap tgotwig/linux-dust && brew install dust`

#### [Pacstall](https://github.com/pacstall/pacstall) (Debian/Ubuntu)

- `pacstall -I dust-bin`

#### Windows:

- Windows GNU version - works
- Windows MSVC - requires: [VCRUNTIME140.dll](https://docs.microsoft.com/en-gb/cpp/windows/latest-supported-vc-redist?view=msvc-170)

#### Download

- Download Linux/Mac binary from [Releases](https://github.com/bootandy/dust/releases)

- move file to executable path: `sudo mv dust /usr/local/bin/`

## 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.

## Usage

```
Usage: dust
Usage: dust <dir>
Usage: dust <dir>  <another_dir> <and_more>
Usage: dust -p (full-path - Show fullpath of the subdirectories)
Usage: dust -s (apparent-size - shows the length of the file as opposed to the amount of disk space it uses)
Usage: dust -n 30  (Shows 30 directories instead of the default [default is terminal height])
Usage: dust -d 3  (Shows 3 levels of subdirectories)
Usage: dust -r (reverse order of output)
Usage: dust -H (si print sizes in powers of 1000 instead of 1024)
Usage: dust -X ignore  (ignore all files and directories with the name 'ignore')
Usage: dust -x (Only show directories on the same filesystem)
Usage: dust -b (Do not show percentages or draw ASCII bars)
Usage: dust -i (Do not show hidden files)
Usage: dust -c (No colors [monochrome])
Usage: dust -f (Count files instead of diskspace)
Usage: dust -t (Group by filetype)
Usage: dust -z 10M (min-size, Only include files larger than 10M)
Usage: dust -e regex (Only include files matching this regex (eg dust -e "\.png$" would match png files))
Usage: dust -v regex (Exclude files matching this regex (eg dust -v "\.png$" would ignore png files))

```

## 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

Note: Apparent-size is calculated slightly differently in dust to gdu. In dust each hard link is counted as using file_length space. In gdu only the first entry is counted.

// File ID:
    // This optimization does deprive us of access to a file ID. As a
    // workaround, we just make one up that hopefully does not collide with real
    // file IDs.
    // Hard links: Unresolved. We don't get inode/file index, so hard links
    // count once for each link. Hopefully they are not too commonly in use on
    // windows.

// Size:
    // We assume (naively?) that for the common cases the free size info is the
    // same as one would get by doing the expensive thing. Sparse, encrypted and
    // compressed files are not included in the common cases, as one can image
    // there being more than view on their size.

// Savings in orders of magnitude in terms of time, io and cpu have been
    // observed on hdd, windows 10, some 100Ks files taking up some hundreds of
    // GBs:
    // Consistently opening the file: 30 minutes.
    // With this optimization:         8 sec.
