uutils coreutils [![Build Status](https://api.travis-ci.org/uutils/coreutils.svg?branch=master)](https://travis-ci.org/uutils/coreutils)

================
uutils is an attempt at writing universal (as in cross-platform) CLI
utils in [Rust](http://rust-lang.org). This repo is to aggregate the GNU
coreutils rewrites.
Why?

2014-02-19 01:52:47 +00:00
Many GNU, Linux and other utils are pretty awesome, and obviously

has been spent in the past to port them to Windows. However, those projects
2014-02-06 05:18:03 +00:00
are either old, abandoned, hosted on CVS, written in platform-specific C, etc.

2014-02-19 01:52:47 +00:00
Rust provides a good, platform-agnostic way of writing systems utils that are easy
2013-08-02 17:24:20 +00:00
to compile anywhere, and this is as good a way as any to try and learn it.
Build Instructions
------------------
To simply build all available utilities:
```
make
```
To build all but a few of the available utilities:
```
make DONT_BUILD='UTILITY_1 UTILITY_2'
```
To build only a few of the available utilities:
```
make BUILD='UTILITY_1 UTILITY_2'
```
2014-06-13 02:14:56 +00:00
To build the multicall binary (_i.e._ BusyBox-like binary):
```
make MULTICALL=1
```
Installation Instructions
-------------------------
To install all available utilities:
```
make install
```
To install all but a few of the available utilities:
```
make DONT_INSTALL='UTILITY_1 UTILITY_2' install
```
To install only a few of the available utilities:
```
make INSTALL='UTILITY_1 UTILITY_2' install
```
To install the multicall binary:
```
make MULTICALL=1 install
```
To install every program (other than the multicall binary) with a prefix:
```
make PROG_PREFIX=PREFIX_GOES_HERE install
```
Uninstallation Instructions
---------------------------
2014-06-13 02:49:00 +00:00

```
make PROG_PREFIX=PREFIX_GOES_HERE uninstall
```
2014-06-13 02:14:56 +00:00
Test Instructions
-----------------

Contribute
----------
Contributions are very welcome, and should target Rust's master branch until
Rust 1.0 is released. You may *claim* an item on the to-do list by following
2013-12-15 19:04:49 +00:00
these steps:
2013-11-30 23:07:22 +00:00
1. Open an issue named "Implement [the utility of your choice]", e.g. "Implement ls"
2. State that you are working on this utility.
3. Develop the utility.
4. Submit a pull request and close the issue. Your pull request should include deleting the utility from the to-do list on this README.
The steps above imply that, before starting to work on a utility, you should search the issues to make sure no one else is working on it.
