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.
