Add prerequisites step for MacOS

timurb commented 4 years ago

MacOS has a bit different flavor of coreutils and currently fzf-obc doesn't work on MacOS. On MacOS there are the following incompatibilities with modern linux distributions:

sed doesn't support -r (I think -E is used instead) and -z options
head -n -1 syntax is not supported. head -n 1 works fine (don't know if in intended way or not)
cut doesn't support -z option
shopt globstar is not supported out of the box

Probably a few more options could be unsupported — I gave up at this point.

I'm using MacOS 10.14.6 Mojave and tried to select tag 1.2.0 for installation.

Actually after proper installation/upgrade of bash, sed and coreutils the issue faded away:

brew install bash
brew install gnu-sed
brew install coreutils
echo "export PATH=/usr/local/opt/coreutils/libexec/gnubin:/usr/local/opt/gnu-sed/libexec/gnubin:/usr/local/sbin:$PATH" >> ~/.bash_profile
chsh -s /usr/local/bin/bash

May be it makes sense to put that into docs.

Hello,

It is already in the docs more or less explicitly but could add a specific section/warning/step for MacOS user.

Thanks for your feedback
