SLoC
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. Optionally delete superfluous data, and do so more quickly than rm
.
Installation
Binary Release
MacOS
curl -LSfs https://raw.githubusercontent.com/Byron/dua-cli/master/ci/install.sh | \
sh -s -- --git Byron/dua-cli --crate dua --tag v2.29.0
MacOS via MacPorts:
sudo port selfupdate
sudo port install dua-cli
MacOS via Homebrew
brew update
brew install dua-cli
Linux
Linux requires the target to be specified explicitly to obtain the MUSL build.
curl -LSfs https://raw.githubusercontent.com/Byron/dua-cli/master/ci/install.sh | \
sh -s -- --git Byron/dua-cli --target x86_64-unknown-linux-musl --crate dua --tag v2.29.0
Windows via Scoop
scoop install dua
Pre-built Binaries
See the releases section for manual installation of a binary, pre-built for many platforms.
Cargo
Via cargo
, which can be obtained using rustup
For Unix…
cargo install dua-cli
# And if you don't need a terminal user interface (most compatible)
cargo install dua-cli --no-default-features
# Compiles on most platforms, with terminal user interface
cargo install dua-cli --no-default-features --features tui-crossplatform
For Windows, nightly features are currently required.
cargo +nightly install dua-cli
VoidLinux
Via xbps
on your VoidLinux system.
xbps-install dua-cli
Fedora
Via dnf
on your Fedora system.
sudo dnf install dua-cli
Arch Linux
Via pacman
on your ArchLinux system.
sudo pacman -S dua-cli
NixOS
Nix-shell (temporary)
nix-shell -p dua
NixOS configuration
environment.systemPackages = [
pkgs.dua
];
NetBSD
Via pkgin
on your NetBSD system.
pkgin install dua-cli
Or, building from source
cd /usr/pkgsrc/sysutils/dua-cli
make install
Windows
You will find pre-built binaries for Windows in the releases section. Alternatively, install via cargo as in
cargo +nightly install dua-cli
x-cmd
x-cmd is a toolbox for Posix Shell, offering a lightweight package manager built using shell and awk.
x env use dua
- Additionally, the
x dua ...
command is available, which automatically installsdua
without affecting the environment, such as not modifying thePATH
variable.
Usage
# 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
Interactive Mode
Launch into interactive mode with the i
or interactive
subcommand. Get help on keyboard
shortcuts with ?
.
Use this mode to explore, and/or to delete files and directories to release disk space.
Please note that great care has been taken to prevent accidential deletions due to a multi-stage process, which makes this mode viable for exploration.
dua i
dua interactive
Development
Please note that all the following assumes a unix system. On Windows, the linux subsystem should do the job.
Run tests
make tests

make
But why is…
…there only one available backend? termion
was available previously.
Maintaining both backends seemed more cumbersome than it's worth and add complexity I didn't like anymore. termion
had its benefits,
but I never liked that it seems to have dropped out of support.
Thus crossterm
is the only remaining backend and it's very actively developed.
Acknowledgements
Thanks to jwalk, all there was left to do is to write a command-line interface. As jwalk
matures, dua should benefit instantly.
Limitations
- Does not show symbolic links at all if no path is provided when invoking
dua
- in an effort to skip symbolic links, for now there are pruned and are not used as a root. Symbolic links will be shown if they are not a traversal root, but will not be followed.
- Interactive mode only looks good in dark terminals (see this issue)
- easy fix: file names in main window are not truncated if too large. They are cut off on the right.
- There are plenty of examples in
tests/fixtures
which don't render correctly in interactive mode. This can be due to graphemes not interpreted correctly. With Chinese characters for instance, column sizes are not correctly computed, leading to certain columns not being shown. In other cases, the terminal gets things wrong - I use alacritty, and with certain characaters it performs worse than, say iTerm3. See https://github.com/minimaxir/big-list-of-naughty-strings/blob/master/blns.txt for the source. - In interactive mode, you will need about 60MB of memory for 1 million entries in the graph.
- In interactive mode, the maximum amount of files is limited to 2^32 - 1 (
u32::max_value() - 1
) entries.- One node is used as to 'virtual' root
- The actual amount of nodes stored might be lower, as there might be more edges than nodes, which are also limited by a
u32
(I guess) - The limitation is imposed by the underlying
petgraph
crate, which declares it asunsafe
to use u64 for instance. - It's possibly UB when that limit is reached, however, it was never observed either.
