**dua** (-> _Disk Usage Analyzer_) is a tool to conveniently learn about the usage of disk space of a given directory. It's parallel by default and will max out your SSD, providing relevant information as fast as possible.
[](https://asciinema.org/a/au3neIHDGtYYj4blyTXR8VkJz)
### Installation
Via `cargo`, which can be obtained using [rustup][rustup]
```
cargo install dua-cli
```
### Usage
```bash
# count the space used in the current working directory
dua
# count the space used in all directories that are not hidden
dua *
# learn about additional functionality
dua aggregate --help
```
### Roadmap
#### 🚧v2.0 (_wip_) - interactive visualization of directory sizes with an option to queue their deletion
A sub-command bringing up a terminal user interface to allow drilling into directories, and clearing them out, all just using the keyboard.
##### Other Features
* [ ] Single Unit Mode, see [reddit](https://www.reddit.com/r/rust/comments/bvjtan/introducing_dua_a_parallel_du_for_humans/epsroxg/)
* [ ] Evaluate unit coloring
#### ✅v1.0 (_released_) - aggregate directories, fast
Simple CLI to list top-level directories similar to sn-sort, but faster and more tailored to getting an idea of where most space is used.
### Development
#### Run tests
```bash
make journey-tests
```
#### Learn about other targets
```
make
```
### Acknowledgements
Thanks to [jwalk][jwalk], all there was left to do is to write a command-line interface. As `jwalk` matures, **dua** should benefit instantly.
### Tradeoffs
* Dedication to `termion`
* we use [`termion`][termion] exlusively, and even though [`tui`][tui] supports multiple backends, we only support its termion backend. _Reason_: `tui` is only used for parts of the program, and in all other parts `termion` is used for coloring the output. Thus we wouldn't support changing to a different backend anyway unless everything is done with TUI, which is really not what it is made for.
