Replace du with dust on Linux
======
The dust command is a more intuitive implementation of the du command
written in Rust.
![Sand dunes][1]
If you work on the Linux command line, you will be familiar with the `du` command. Knowing commands like `du` , which returns information about disk usage quickly, is one of the ways the command line makes programmers more productive. Yet if you're looking for a way to save even more time and make your life even easier, take a look at [dust][2], which is `du` rewritten in Rust with more intuitiveness.
In short, `dust` is a tool that provides a file's type and metadata. If you trigger `dust` in a directory, it will report that directory's disk utilization in a couple of ways. It provides a very informative graph that tells you which folder is using the most disk space. If there is a nested folder, you can see the percentage of space used by each folder.
### Install dust
You can install `dust` using Rust's Cargo package manager:
```
`$ cargo install du-dust`
```
Alternately, you might find it in your software repository on Linux, and on macOS, use [MacPorts][3] or [Homebrew][4].
### Explore dust
Issuing the `dust` command on a directory returns a graph that shows its contents and what percentage each item holds in a tree format.

To apply `dust` to a specific directory:
```
`$ dust ~/Work/`
```

The `-r` option shows the output in reverse order, with root at the bottom:
```
`$ dust -r ~/Work/`
```
Using `dust -d 3` returns three levels of subdirectories and their disk utilization:
```
`$ dust -d 3 ~/Work/wildfly/jaxrs/target/classes` [/code] [code]
$ dust -d 3 ~/Work/wildfly/jaxrs/target/classes

### Conclusion
The beauty of `dust` lies in being a small, simple, and easy-to-understand command. It uses a color scheme to denote the largest subdirectories, making it easy to visualize your directory. It's a popular project, and contributions are welcome.
