I found there is some differences between the utility command I used on the mac OSX and linux. I want to make my experience united.

How could I replace all my mac utilities with GNU utilities?

    I sympathize with your frustrations but I believe that, in the long term, it will cause greater frustration if they are replaced - After seeking to do the same thing I'd recommend using homebrew as mentioned below, and then just learning to use the utilities with a g ( gsed, greadlink, etc ) instead of replacing the system utilities. – cwd Mar 29 '15 at 13:51
  • For grep, see apple.stackexchange.com/questions/193288/… – Dan Pritts Apr 19 '16 at 17:28

    I disagree with @cwd, using --with-default-names is only affects the local user. It could be an issue with mac oriented terminal utilities, but if you use homebrew for everything, you might aswell pretend you're using linux. Mixed with iterm2, it's working great for me, I can basically pretend I'm home with my linux boxes. – Ray Foss Jun 30 '17 at 17:39

This adds symlinks for GNU utilities with g prefix to /usr/local/bin/:

brew install coreutils findutils gnu-tar gnu-sed gawk gnutls gnu-indent gnu-getopt grep

See brew search gnu for other packages. If you want to use the commands without a g prefix add for example /usr/local/opt/coreutils/libexec/gnubin before other directories on your PATH.

$ brew info coreutils
coreutils: stable 8.21
http://www.gnu.org/software/coreutils
Depends on: xz
/usr/local/Cellar/coreutils/8.20 (208 files, 9.4M)
/usr/local/Cellar/coreutils/8.21 (210 files, 9.6M) *
https://github.com/mxcl/homebrew/commits/master/Library/Formula/coreutils.rb
==> Caveats
All commands have been installed with the prefix 'g'.

If you really need to use these commands with their normal names, you
can add a "gnubin" directory to your PATH from your bashrc like:

    PATH="/usr/local/opt/coreutils/libexec/gnubin:$PATH"

Additionally, you can access their man pages with normal names if you add
the "gnuman" directory to your MANPATH from your bashrc as well:

    MANPATH="/usr/local/opt/coreutils/libexec/gnuman:$MANPATH"

    FWIW, I have a Homebrew Formula that acts as a meta-package for all those great GNU utils: see shiny-and-gnu.rb in github.com/al-the-x/homebrew-mine – AL the X May 13 '14 at 20:47

    The first PATH works, but MANPATH failed, why? Is it because I'm using OSX10.10? I echoed $MANPATH, and I got /usr/local/opt/coreutils/libexec/gnuman:, seems original MANPATH wasn't include. After commented out the MANPATH conf in my bashrc, I got nothing by ecoh $MANPATH. And of course, if I use man pwd, I got the BSD manual. How to fix this? – Zen Mar 5 '15 at 15:42

    For findutils, you need to add PATH="/usr/local/Cellar/findutils/4.4.2/bin:$PATH" which is not stated in the installation console output. – Sridhar Sarnobat Apr 28 '15 at 20:09

    In addition, to get the right man page for findutils, add this to your $MANPATH /usr/local/opt/findutils/share/man – Christian Long Aug 3 '15 at 19:05

    @Zen: the right way to initiate MANPATH so as to keep the default system value is: MANPATH="/usr/local/opt/coreutils/libexec/gnuman:${MANPATH-/usr/share/man}". The key is in the construct ${var-default_value}. – dan Oct 6 '15 at 7:43

Besides brew install coreutils, you may also need to install some other packages, such as gnu-sed, grep:

brew install findutils
brew install gnu-indent
brew install gnu-sed
brew install gnutls
brew install grep
brew install gnu-tar
brew install gawk

Note that the --with-default-names option is removed since January 2019, so each binary has to be added to the path if they are to be used without the g prefix.

Old reference (when --with-default-names was available): http://www.topbug.net/blog/2013/04/14/install-and-use-gnu-command-line-tools-in-mac-os-x/

  • Note that brew install gawk (unlike all the others) will replace awk (via a symbolic link /usr/local/bin/awk). If you want to keep the original /usr/bin/awk, just rm /usr/local/bin/awk – wisbucky Jun 1 at 10:48

I'm not sure that I would recommend replacing them; however, you can install them to a different path and utilize them that way. Overall, if you are coming from Linux and would like access to more "generic" *nix utilities, and a system similar to apt, then I would recommend looking into Macports: http://www.macports.org

It allows, for example, using the latest "generic" GCC, as opposed to/in addition to Apple's included GCC, just as an example.

    For instance, tar and zip from Mac OS X know about metadata that the GNU versions do not. – lhf Oct 22 '12 at 17:49

    There are Apple supplied apps, which are just GUIs for some command line tools and if you replace them the apps may start behaving strangely, so go with adding, not replacing. – Ɱark Ƭ Oct 23 '12 at 11:56
  • Right; something like Macports adds them, it doesn't replace them. – Jonathan Oct 23 '12 at 12:10
  • If you want to use the GNU utilities by default with MacPorts you can add /opt/local/libexec/gnubin to the front of your PATH environment variable. – markshep Sep 26 '16 at 11:59

I've written a script to do exactly this! The script can be viewed here (or below). However, I can't always guarantee this post will reflect the latest version of the script linked previously.

Upon running the script, Homebrew will be installed (if not already), all the associated GNU utilities will be installed (if not already), and the PATH variable will be built from the installed utilities.

#!/bin/bash

# Install Homebrew (if not already installed)
ruby -e "$(curl -fsSL "\
"https://raw.githubusercontent.com/Homebrew/install/master/install)"

# Install required packages from Homebrew
brew tap homebrew/dupes
brew install coreutils binutils diffutils ed findutils gawk gnu-indent gnu-sed \
  gnu-tar gnu-which gnutls grep gzip screen watch wdiff wget bash gdb gpatch \
  m4 make nano file-formula git less openssh python rsync svn unzip vim \
  --default-names --with-default-names --with-gettext --override-system-vi \
  --override-system-vim --custom-system-icons

# Empty the .bash_path file that holds GNU paths
> ~/.bash_path

# Build PATH variable script in ~/.bash_path
for i in /usr/local/Cellar/*/*/bin; do
  echo 'export PATH="'$i':$PATH"' >> ~/.bash_path
done
for i in /usr/local/Cellar/*/*/libexec/gnubin; do
  echo 'export PATH="'$i':$PATH"' >> ~/.bash_path
done
for i in /usr/local/Cellar/*/*/share/man; do
  echo 'export MANPATH="'$i':$MANPATH"' >> ~/.bash_path
done
for i in /usr/local/Cellar/*/*/libexec/gnuman; do
  echo 'export MANPATH="'$i':$MANPATH"' >> ~/.bash_path
done

# Check if .bash_path is being called from .bash_profile
PATCH=`grep "~/.bash_path" ~/.bash_profile`
if [ "$PATCH" == "" ]; then
  # Add Ubuntu-style PS1 to .bash_profile
  cat <<EOF > ~/.bash_profile
export PS1="\[\033[1;32m\]\u@\h\[\033[0m\]:\[\033[1;34m\]\w\[\033[0m\]# "
EOF
  # Add .bash_path to .bash_profile
  echo "source ~/.bash_path" >> ~/.bash_profile
fi

    Don't you just love the downvotes with no critical comments? Thank you for the script. – Justin Force Nov 30 '15 at 22:14
  • @JustinForce No problem! Thank you for the feedback. – Clay Freeman Dec 1 '15 at 2:29

    -1. This scripts does too much magic. All of the .bash_path-mangling is not really necessary if you follow @user495470 and @xuhdev's answers. And changing PS1 is completely out of the scope of this question. – Greg Dubicki Jan 27 '16 at 11:40

    @GregDubicki unfortunately, the bash path "mangling" is required for some of these packages. You may check this for yourself. In regard to changing PS1: this script is for personal use. Anyone who wishes to revert it may do so very easily. – Clay Freeman Jan 30 '16 at 5:23

I have written a script that transparently transforms the macOS CLI into a fresh GNU/Linux CLI experience by

  • installing missing GNU programs
  • updating outdated GNU programs
  • replacing pre-installed BSD programs with their preferred GNU implementation
  • installing other programs common among popular GNU/Linux distributions

https://github.com/fabiomaia/linuxify

git clone https://github.com/fabiomaia/linuxify.git
cd linuxify/
./linuxify install

It also allows you to easily undo everything.

./linuxify uninstall

    Trying to run first command (git clone git@github.com.:fabiomaia/linuxify.git) It first said "The authenticity of host 'github.com' can't be established etc.". I typed yes and pressed Enter. Then it said git@github.com: Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. What's wrong? – izogfif Mar 11 at 5:46
  • @izogfif Try cloning with HTTPS instead git clone https://github.com/fabiomaia/linuxify.git – fabiomaia Mar 11 at 16:30

    Yes, that worked. Please, update your answer (also, remove those dollars at the start - they're copied when select text and copy-paste into console). – izogfif Mar 12 at 5:38
  • @izogfif Thank you for the suggestions. – fabiomaia Mar 12 at 18:25
