Install GNU in Mac OS

If you don't know what's GNU, check here ( and here (

Why Mac OS does not come with GNU? Here is what I extracted from Hong Xu's comment:
Because OS X is mainly BSD based -- the same reason why FreeBSD/OpenBSD/NetBSD does not use GNU tools by default. Another reason that Apple bundles many outdated GNU software (bash, gdb, etc.) is that the new GPLv3 doesn't allow Apple to do so, while GPLv2 is fine with this behavior. After many GNU projects upgraded to GPL v3, Apple won't be able to bundle them any more.
I found it's very easy to install GNU in Max OS just following Hong Xu's blog:

Also recommend the friendly tool of Homebrew:

Basically, here is step:

ruby -e "$(curl -fsSL"

brew install coreutils  # contain most of what you want
brew install binutils 
brew install diffutils 
brew install ed --default-names 
brew install findutils --default-names 
brew install gawk 
brew install gnu-indent --default-names 
brew install gnu-sed --default-names 
brew install gnu-tar --default-names 
brew install gnu-which --default-names 
brew install gnutls --default-names 
brew install grep --default-names 
brew install gzip 
brew install screen 
brew install watch 
brew install wdiff --with-gettext 
brew install wget


  1. You can also use MacPorts and Fink to install GNU tools....

    1. Thanks. I was using Fink for that purpose, but didn't know MacPorts. Good to know :)
