맥에서 가끔 특정명령을 실행시킬 경우 readlink: illegal option –f 라는 에러가 발생되는 경우가 있습니다. GNU 에서 만든 유틸을 맥에서 사용하는 경우 종종 이와 같은 오류가 발생하는데요.
greadlink 라는 유틸을 대체하여 사용하면 해결 하면 됩니다.
❯ greadlink --help

==> 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"

~ 51s- greadlink 파일이 설치되었는지 확인 합니다.
❯ which greadlink
/usr/local/bin/greadlink- readlink 명령 실행시 greadlink 가 실행 될 수 있도록 심볼릭 링크를 설정 합니다.
❯ ln -s "$(which greadlink)" "$(dirname "$(which greadlink)")/readlink"
