readlink: illegal option -- f

Error:

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

I'm working around this ....

The problem seems to be for OSX users.
I found a solution in this stackoverflow post :
https://stackoverflow.com/questions/1055671/how-can-i-get-the-behavior-of-gnus-readlink-f-on-a-mac#answer-4031502

brew install coreutils
greadlink -f file.txt

But after you have to say your system to use greadlink instead of readlink.
Alias not always do the stuff, better remove system readlink and put a symlink :
sudo ln -s <PATH_TO_greadlink> /bin/readlink
