     For each file name in NAMES return the canonical absolute name.  A
     canonical name does not contain any `.' or `..' components, nor
     any repeated path separators (`/') or symlinks.  In case of a
     failure the empty string is returned.  Consult the `realpath(3)'
                                            ^^^^^^^^^^^^^^^^^^^^^^^^^
     documentation for a list of possible failure causes.
     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^


  So try running "man 3 realpath", or googling "opengroup realpath" for the
posix standard.  The main failure cause would be when the path doesn't
currently exist, i.e. $(realpath dir1/dir2/non-existent-dir/..) and the like
won't work.
