Used in coreutils
uutils coreutils is a cross-platform reimplementation of the GNU coreutils in Rust. While all programs have been implemented, some options might be missing or different behavior might be experienced.
To install it:
cargo install coreutils
uutils aims to be a drop-in replacement for the GNU utils. Differences with GNU are treated as bugs.
uutils aims to work on as many platforms as possible, to be able to use the same utils on Linux, Mac, Windows and other platforms. This ensures, for example, that scripts can be easily transferred between platforms.
uutils has both user and developer documentation available:
Both can also be generated locally, the instructions for that can be found in the coreutils docs repository.
- Rust (
- GNU Make (optional)
uutils follows Rust's release channels and is tested against stable, beta and
nightly. The current Minimum Supported Rust Version (MSRV) is
There are currently two methods to build the uutils binaries: either Cargo or GNU Make.
Building the full package, including all documentation, requires both Cargo and Gnu Make on a Unix platform.
For either method, we first need to fetch the repository:
git clone https://github.com/uutils/coreutils
Building uutils using Cargo is easy because the process is the same as for every other Rust program:
cargo build --release
This command builds the most portable common core set of uutils into a multicall (BusyBox-type) binary, named 'coreutils', on most Rust-supported platforms.
Additional platform-specific uutils are often available. Building these expanded sets of uutils for a platform (on that platform) is as simple as specifying it as a feature:
cargo build --release --features macos
# or ...
cargo build --release --features windows
# or ...
cargo build --release --features unix
If you don't want to build every utility available on your platform into the final binary, you can also specify which ones you want to build manually. For example:
cargo build --features "base32 cat echo rm" --no-default-features
If you don't want to build the multicall binary and would prefer to build the
utilities as individual binaries, that is also possible. Each utility is
contained in its own package within the main repository, named "uu_UTILNAME". To
build individual utilities, use cargo to build just the specific packages (using
-p] option). For example:
cargo build -p uu_base32 -p uu_cat -p uu_echo -p uu_rm
make is a simple process as well.
To simply build all available utilities:
In release mode:
To build all but a few of the available utilities:
make SKIP_UTILS='UTILITY_1 UTILITY_2'
To build only a few of the available utilities:
make UTILS='UTILITY_1 UTILITY_2'
Install with Cargo
Likewise, installing can simply be done using:
cargo install --path . --locked
This command will install uutils into Cargo's bin folder (e.g.
This does not install files necessary for shell completion or manpages. For
manpages or shell completion to work, use
GNU Make or see
Manually install shell completions/
Manually install manpages.
Install with GNU Make
To install all available utilities:
To install using
-E must be used:
sudo -E make install
To install all but a few of the available utilities:
make SKIP_UTILS='UTILITY_1 UTILITY_2' install
To install only a few of the available utilities:
make UTILS='UTILITY_1 UTILITY_2' install
To install every program with a prefix (e.g. uu-echo uu-cat):
make PROG_PREFIX=PREFIX_GOES_HERE install
To install the multicall binary:
make MULTICALL=y install
Set install parent directory (default value is /usr/local):
# DESTDIR is also supported
make PREFIX=/my/path install
make installs shell completions for all installed utilities
zsh. Completions for
powershell can also
be generated; See
Manually install shell completions.
Manually install shell completions
coreutils binary can generate completions for the
zsh shells. It prints the result to stdout.
The syntax is:
cargo run completion <utility> <shell>
So, to install completions for
cargo run completion ls bash > /usr/local/share/bash-completion/completions/ls
Manually install manpages
To generate manpages, the syntax is:
cargo run manpage <utility>
So, to install the manpage for
cargo run manpage ls > /usr/local/share/man/man1/ls.1
Un-installation differs depending on how you have installed uutils. If you used Cargo to install, use Cargo to uninstall. If you used GNU Make to install, use Make to uninstall.
Uninstall with Cargo
To uninstall uutils:
cargo uninstall uutils
Uninstall with GNU Make
To uninstall all utilities:
To uninstall every program with a set prefix:
make PROG_PREFIX=PREFIX_GOES_HERE uninstall
To uninstall the multicall binary:
make MULTICALL=y uninstall
To uninstall from a custom parent directory:
# DESTDIR is also supported
make PREFIX=/my/path uninstall
GNU test suite compatibility
Below is the evolution of how many GNU tests uutils passes. A more detailed breakdown of the GNU test results of the main branch can be found in the user manual.
See https://github.com/orgs/uutils/projects/1 for the main meta bugs (many are missing).
