View disk space usage and delete unwanted data, fast.
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.
Run dua i to launch the interactive mode for exploring and deleting files.

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 duascoop install dua

See the releases section for manual installation of a binary, pre-built for many platforms.
Release archives include build provenance attestations. After downloading an archive, verify that it was built by this repository with the GitHub CLI:
gh attestation verify ./dua-v2.39.1-aarch64-apple-darwin.tar.gz --repo Byron/dua-cli
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.

x-cmd is a toolbox for Posix Shell, offering a lightweight package manager built using shell and awk.
x env use dua
x dua ... command is available, which automatically installs dua without affecting the environment, such as not modifying the PATH variable.# 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
On macOS, the --deduplicate-apfs-clones traversal option counts fully shared
APFS file clones only once in aggregate and interactive runs. It is opt-in
because collecting the additional metadata reduces traversal performance.
Files that share only some blocks are not deduplicated, and --apparent-size
still reports each file's logical length.
By default aggregate prints a flat listing. Pass --depth N to instead print an indented tree
that descends N levels into each input, which is handy for sharing a disk-usage report without
opening interactive mode. The inputs form the first level, so --depth 1 lists just them, the same
set of entries the flat listing shows.
# show each top-level entry and one level below it
dua aggregate --depth 2--no-sort and --no-total work the same way they do for the flat listing.
--ignore-from FILE reads gitignore-style patterns and leaves everything they match out of the
report, in both aggregate and interactive mode. This is the --exclude-from of rsync and the
--exclude-file of restic, so the same file can answer "how much of this would actually get
backed up?".
cat .duaignore # /target/ # **/node_modules/ # *.log # !important.log dua --ignore-from .duaignore
Patterns follow .gitignore syntax - # comments, a trailing / to match directories only, a
leading / to anchor to the current working directory or the traversal root, ** to span directories,
and ! to re-include something an earlier pattern excluded. They match the paths dua reports,
which are relative to the directory being looked at, and matching is case-sensitive on every platform.
The option can be given more than once, in which case later files win over earlier ones, and it
can also be set through DUA_IGNORE_FROM. Excluded directories are not descended into at all, so
their contents cannot be re-included - the same restriction Git has.
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.
Press ] to minimize or restore the entire right side. Tab cycles through visible panes;
? restores and focuses Help when the right side is minimized.
Please note that great care has been taken to prevent accidental deletions due to a multi-stage process, which makes this mode viable for exploration.
dua i dua interactive
The interactive interface can be localized via the standard POSIX locale environment variables,
in the usual order of precedence LC_ALL > LC_MESSAGES > LANG. English is the default. The
following translations are listed in the order they were added: German (de), Japanese (ja),
Korean (ko), and Simplified Chinese (zh, zh_CN, zh_SG, or zh_Hans). They are available
when the locale uses UTF-8 or omits the codeset:
Please open an issue to request support for your language, if you would be available for reviewing it as well.
LANG=de_DE.UTF-8 dua i # German interface LANG=ja_JP.UTF-8 dua i # Japanese interface LANG=ko_KR.UTF-8 dua i # Korean interface LANG=zh_CN.UTF-8 dua i # Simplified Chinese interface
dua clean [DIRECTORY]... finds disposable directories and lists them largest first as sizing
finishes. With no paths, it searches the current directory. Nothing is deleted automatically.
dua clean ~/dev dua clean --depth 3 ~/dev ~/Downloads
Candidates include node_modules, Python caches and virtual environments, Cargo project target
directories, and Zig's .zig-cache, zig-cache, and zig-out. In Git repositories, candidates
must be ignored and contain no tracked files. Directories containing a .git entry (regardless
of case) and paths excluded by traversal options are skipped.
The hub groups sibling candidates and deeper candidates under their shared parent. Open a group to browse, sort, or search within it; go back to return to the hub. Use the usual marking and deletion keys. Marking a group selects only its candidates, leaving other contents untouched.
R in the hub repeats discovery; r rechecks the selected candidate or existing group members.--depth 0 checks only the supplied directories for great speedups;
candidates are always sized completely.Traversal options, --no-entry-check, and --once are supported. Parent scanning, snapshot
import, and snapshot export are unavailable.
dua stacks prints folded stacks—the "collapsed" interchange format read by flame-graph tools.
Each line is an entry's path with ; between its components, a space, and its size in bytes:
dua stacks > disk-usage.foldeddua flamegraph renders the same data with inferno, writes
the SVG to a temporary file, and opens it. Pass an output path to write the SVG without opening it.
Both commands accept the usual traversal options as well as --depth and --import:
dua flamegraph dua flamegraph -o disk-usage.svg
dua can read an optional configuration file from your OS-specific config directory:
$XDG_CONFIG_HOME/dua-cli/config.toml (or the platform default config dir)~/Library/Application Support/dua-cli/config.toml%APPDATA%\dua-cli\config.tomlIf the file is missing, defaults are used.
Run dua config show-default for a commented template containing every configurable keybinding.
Use a string for one binding or an array for aliases; an empty array disables the action.
For example:
[keys] # If true (default), close_pane keys ascend from the main pane. # If false, close_pane keys follow the quit behavior. esc_navigates_back = true close_pane = "esc" toggle_right_panes = "]" sort_by_name = "ctrl+n" # Disable permanent deletion and moving entries to the trash. delete_marked = [] trash_marked = []
Please note that all the following assumes a unix system. On Windows, the linux subsystem should do the job.

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.

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 characters it
performs worse than, say iTerm3.
