Ask what "tf" is up with this cmd, which is often a symlinked-file (think brew Cellars). Also good for getting to a python-cli wrapper's lib dir.

typify-file.sh

typify-file ()
{
    opwd="$PWD";
    type -a "$1";
    cmdpath=$(type -P "$1");
    if ( test -e "$cmdpath" ); then
        count=0;
        while ( test -L "$cmdpath" ); do
            (( count++ ));
            linkrelative=$(readlink -n "$cmdpath");
            pink="$PURPLE";
            ec="\033[0m";
            printf "\t${count}. ${pink}${cmdpath}${ec} ---> ${linkrelative}\n";
            cmdpathdir="$(dirname "$cmdpath")";
            cd "$cmdpathdir";
            cmdpath="$(realpath -s "$linkrelative")";
        done;
        printf "\nFILE: ";
        \file -h --no-dereference "$cmdpath" | sed 's/:/\n>> /';
        printf "\nMIME: ";
        \file -h --no-dereference --mime-type -b "$cmdpath";
        echo;
        echo "cd - ... to go to the final dir";
    fi;
    cd "$owd"
