Solve MacOS under Readlink:illegal option--F

Mac Readlink does not have the-f parameter, such as Screenfetch will go to call readlink-f, so each time will appear:

 
readlink: illegal option -- f
usage: readlink [-n] [file ...]

Very annoying, the solution is as follows:
1. Install Coreutils:

brew install coreutils

2. Set environment variables, edit ~/.bash_profile, add:

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

3. Create aliases, use Greadlink instead of Readlink, edit ~/.bash_profile, add:

alias readlink=greadlink
