Hard drive space on a system can fill up quickly, especially when new software is installed. System administrators frequently have to review disk space utilization and see what files or directories are using up the most storage. This can be accomplished using the Linux
du command, but many users find it cumbersome and awkward to use. The open-source dust program offers a new way of looking at disk space usage more intuitively and straightforwardly. This guide explains how to install and use the dust utility on Linux and how it functions as a du replacement.
Dust was developed as an alternative to the
du command to allow users to quickly check disk usage on Linux systems. The name of the application is a portmanteau of “du” and Rust, the programming language it is written in. The name of the utility is intentionally left uncapitalized. Dust can be installed by using the Homebrew or Cargo package managers.
Dust reports on the disk utilization and graphically presents the results. It provides an instant overview of the file system with no further sorting or piping of commands. Dust emphasizes the largest directories and intelligently parses the directory tree to find large subdirectories. This allows users to quickly determine which directories are using the most space and where these directories are located within the file hierarchy. Dust operates on specific directories and handles both directories and files.
Dust’s interface uses a monochromatic scale to illustrate how deep in the hierarchy a directory is and the location of its parent directories. Darker tints correspond to base-level directories near the root of the file system. Lighter shades of grey indicate subdirectories several levels deep in the hierarchy.
Dust has several flags and command options to organize the output and determine what entries to display. It examines the size of the terminal window to decide how many items to display.
Disk space statistics have traditionally been retrieved using the
du (disk usage) and
df (disk free) commands. Both of these commands are part of the standard Linux command syntax. These commands supply many options to filter and organize the output, but inexperienced users often find them cryptic and difficult to use. They often have to be combined with
sort to be truly useful. Consult the man page for du for a list of all of the
du command options.
du command provides a highly detailed view of the disk space consumed by each file and subdirectory. However, it often returns thousands of lines of information. It is difficult to skim this information or easily discern the file directory structure.
12 ./.cargo/registry/index/github.com-1ecc6299db9ec823/.git/logs/refs/remotes/origin ...
For this reason, the results of the
du command are often piped to other commands. For example, the following command calculates the total size of all the files in each directory. It then sorts and displays the directories by total disk space usage.
du -hs * | sort -h
df command is used to provide a quick overview of the space available on each hard drive. However, it provides only a brief summary without much additional information.

By contrast, the
dust command allows users to quickly and easily determine how disk space is being used. Although flags and options are available, they are not necessary to effectively use the command. The output is presented in a graphical format, which is not available for the
A good strategy is to use dust to get a quick overview of the system’s disk space allocation. Then use
du on specific directories or files, sorting and filtering the output as necessary.

sudo. If you are not familiar with the
sudocommand, see the Linux Users and Groups guide.
There are three main ways of installing Dust. Either use the Cargo or Homebrew package managers or download a release and unzip it. The following commands are geared towards Ubuntu users but are generally applicable for all Linux distributions.
The easiest way to install Dust is by using the Cargo utility. Cargo is the package manager for Rust, a popular high-performance programming language. If Rust is already installed on the system, then Cargo is installed too. If not, Cargo can be installed as a stand-alone application by using
Ensure the system is fully updated using the instructions in the Before You Begin section. Install Cargo using
sudo apt install cargo
--versionoption to verify the release and confirm Cargo has been installed correctly.
Use Cargo to install dust. Cargo confirms the application has been installed and also provides a warning about the path variable.
cargo install du-dust
Installed package `du-dust v0.7.0` (executable `dust`)
To run Dust from anywhere without specifying the full pathname to the binary, add it to your
.bashrcfile. Open this file in any text editor.
Add the following line to the end of the file.
- File: ~/.bashrc
.bashrcfile to apply the changes.
To verify the installation, use the
-Vflag to see what release of Dust is installed. If there is an error, ensure you have updated the
Dust can also be installed using Homebrew. Homebrew is a package manager that installs new programs into their own directory and adds the appropriate link to the
/usr/local directory. This eliminates the requirement to edit the
.bashrc file. To install dust using Homebrew, follow the instructions below.
If Homebrew is not already installed, download and install it using the following command. The installation program allows you to install the program either in its own directory or in your user directory.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Add the Homebrew executable to your profile. Substitute your username for
useridin the first command below.
echo 'eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"' >> /home/userid/.profile eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"
(Optional) Homebrew recommends installing the
build-essentialpackage to enhance functionality.
sudo apt-get install build-essential
gccto avoid warnings and errors.
brew install gcc
To verify Homebrew is installed and working properly, use the
brew doctorcommand.To see all of the Homebrew commands, use the
Your system is ready to brew.
Install dust using Homebrew.
brew tap tgotwig/linux-dust && brew install dust
To verify the installation, use the
-Vflag to see what release of Dust is installed.
Dust 0.7.0Homebrew can also be used on the macOS. To install Homebrew on a Mac, see the Homebrew page for instructions. To install dust on a Mac using Homebrew, use
brew install dust. The
tapcommand is not necessary for macOS.
You can download the dust executable directly and unzip it.
Download the executable to install from the dust GitHub downloads page.
sudo wget https://github.com/bootandy/dust/archive/refs/tags/v0.7.0.tar.gz
tarutility to unzip the file. Substitute the name of the actual
.gzfile in the following command.
tar -xvf v0.7.0.tar.gz
Move the executable to the correct location.
sudo mv dust-0.7.0 /usr/local/bin/
To verify the installation, use the
-Vflag to see what release of Dust is installed.
The examples in this section illustrate how to use the
dust command to check disk space usage on any Linux-based system. To review disk space usage for your home directory, enter
dust without any additional parameters.
If the terminal window is large enough, dust displays a gray-scale representation of the directory structure in the form of an ASCII bar. Directories at the same level are represented with the same pattern. Breaks in the patterns can be used to identify the subdirectories within any given directory. For example, for the
index directory, locate the dividing line between the gray and white portions of its ASCII bar. Follow this discontinuity upwards to locate all the directories inside
To exclude the ASCII bars and the percentages, add the
-b option. The bars are also excluded if the terminal is too small to display them. For a monochrome display, append the

For those looking for more choices, there are a few other open-source utilities that can be used to graphically illustrate disk space usage.
The du-tree program is very similar to dust. It even has a similar interface. It can be installed using the command
cargo install dutree. ncdu is a simpler utility designed for speed and efficiency. Unfortunately, it is not available through any common package manager and must be downloaded.
Dust provides a nice alternative to the Linux
du command. The
dust command allows users to quickly check disk space usage on any Linux system and see the results in an intuitive graph-based format. Dust can be installed using the Cargo and Homebrew utilities. It can also be downloaded as an
Dust provides several options to allow users to see the most relevant results in the appropriate format. The number of results can be adjusted, multiple directories can be combined, and specific entries can be ignored. As alternatives to dust, several similar free open source programs are also available.
