  1. This script contains three calls to stat (when one would do) all of which will fail if the filename contains spaces.

    It will also fail if the version of stat takes a different syntax (as the *BSD version does).

    stat -c ‘Time of last access : %x
    Time of last modification : %y
    Time of last change : %z’ “$file”
