Cross-platform Rust rewrite of the GNU coreutils
uutils is an attempt at writing universal (as in cross-platform) CLI utilities in Rust. This repository is intended to aggregate GNU coreutils rewrites.
Many GNU, Linux and other utilities are useful, and obviously some effort has been spent in the past to port them to Windows. However, those projects are either old and abandoned, are hosted on CVS (which makes it more difficult for new contributors to contribute to them), are written in platform-specific C, or suffer from other issues.
Rust provides a good, platform-agnostic way of writing systems utilities that are easy to compile anywhere, and this is as good a way as any to try and learn it.
uutils follows Rust's release channels and is tested against stable, beta and nightly. The current oldest supported version of the Rust compiler is
On both Windows and Redox, only the nightly version is tested currently.
There are currently two methods to build uutils: GNU Make and Cargo. However, while there may be two methods, both systems are required to build on Unix (only Cargo is required on Windows).
First, for both methods, we need to fetch the repository:
bash $ git clone https://github.com/uutils/coreutils $ cd coreutils
Building uutils using Cargo is easy because the process is the same as for every other Rust program: ```bash
$ cargo build --release ```
Because the above command attempts to build utilities that only work on Unix-like platforms at the moment, to build on Windows, you must do the following: ```bash
$ cargo build --release --no-default-features --features windows ```
If you don't want to build every utility available on your platform into the multicall binary (the Busybox-esque binary), you can also specify which ones you want to build manually. For example:
bash $ cargo build --features "base32 cat echo rm" --no-default-features
If you don't even want to build the multicall binary and would prefer to just build the utilities as individual binaries, that is possible too. For example:
bash $ cargo build -p uu_base32 -p uu_cat -p uu_echo -p uu_rm
makeis a simple process as well.
To simply build all available utilities:
bash $ make
To build all but a few of the available utilities:
bash $ make SKIP_UTILS='UTILITY_1 UTILITY_2'
To build only a few of the available utilities:
bash $ make UTILS='UTILITY_1 UTILITY_2'
Likewise, installing can simply be done using:
bash $ cargo install
This command will install uutils into Cargo's bin folder (e.g.
To install all available utilities:
bash $ make install
To install using
-Emust be used:
bash $ sudo -E make install
To install all but a few of the available utilities:
bash $ make SKIP_UTILS='UTILITY_1 UTILITY_2' install
To install only a few of the available utilities:
bash $ make UTILS='UTILITY_1 UTILITY_2' install
To install every program with a prefix (e.g. uu-echo uu-cat):
bash $ make PROG_PREFIX=PREFIX_GOES_HERE install
To install the multicall binary:
bash $ make MULTICALL=y install
Set install parent directory (default value is /usr/local): ```bash
$ make PREFIX=/my/path install ```
nix-env -iA nixos.uutils-coreutils
Uninstallation 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.
To uninstall uutils:
bash $ cargo uninstall uutils
To uninstall all utilities:
bash $ make uninstall
To uninstall every program with a set prefix:
bash $ make PROG_PREFIX=PREFIX_GOES_HERE uninstall
To uninstall the multicall binary:
bash $ make MULTICALL=y uninstall
To uninstall from a custom parent directory: ```bash
$ make PREFIX=/my/path uninstall ```
Testing can be done using either Cargo or
Just like with building, we follow the standard procedure for testing using Cargo:
bash $ cargo test
cargo testonly runs the common programs. To run also platform specific tests, run:
bash $ cargo test --features unix
If you would prefer to test a select few utilities:
bash $ cargo test --features "chmod mv tail" --no-default-features
bash $ gdb --args target/debug/coreutils ls (gdb) b ls.rs:79 (gdb) run
To simply test all available utilities:
bash $ make test
To test all but a few of the available utilities:
bash $ make SKIP_UTILS='UTILITY_1 UTILITY_2' test
To test only a few of the available utilities:
bash $ make UTILS='UTILITY_1 UTILITY_2' test
To include tests for unimplemented behavior:
bash $ make UTILS='UTILITY_1 UTILITY_2' SPEC=y test
This testing functionality is only available on *nix operating systems and requires
To run busybox's tests for all utilities for which busybox has tests
bash $ make busytest
To run busybox's tests for a few of the available utilities
bash $ make UTILS='UTILITY_1 UTILITY_2' busytest
To pass an argument like "-v" to the busybox test runtime
bash $ make UTILS='UTILITY_1 UTILITY_2' RUNTEST_ARGS='-v' busytest
