A cross-platform port of GNU's coreutils to Go

Go coreutils

This is a port of GNU's coreutils (http://www.gnu.org/software/coreutils/) that aims to be a drop-in, cross-platform replacement.

It's currently under development.

Because it imports from github.com/EricLagergren/go-gnulib, and I'm constantly refactoring, parts could break from day-to-day.

I'd recommend running go get -u ... before you file a bug report!

Pull requests are more than welcome.

Also, see https://www.github.com/EricLagergren/go-gnulib for a similar project that this project depends on.

• chown note: Currently refactoring from the ground-up.

Side notes:

• Unix should include OS X unless otherwise specified.
• Gofmt means it needs its styling changes (e.g. variable names, formatting, etc.)
• Idiomatic means it needs to be changed to more idiomatic Go
• Windows coverage will increase when I get a Windows laptop

Information:

These utilities should be nearly identical to GNU's coreutils, and should have relatively the same speed.

For example, wc.go counts chars in 550MB file in < 15sec and wc.c in ~11sec on an Intel core i3 2.66ghz. (Running Debian 3.2.63-2+deb7u1 x86_64.)

xxd.go is actually much faster than the native xxd implementation found on most *nix machines -- try it out!

It (as a whole) is licensed under the GPLv3 because it's mostly a transliteraiton of GNU's coreutils, which are licensed under the GPL.

However, all parts are/can be licensed individually, as not all are under the GPL (e.g., xxd was public domain).
