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="$(brew --prefix coreutils)/libexec/gnubin:$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="$(brew --prefix coreutils)/libexec/gnuman:$MANPATH"
