${CBOLD}MODES${CNORMAL}
    Changes Permission recursively on files/directories.
    <dirmode>  defines mode to be set for directories
    <filemode> defines mode to be set for files

    The modes are the same accepted by chmod(1).
    If they're not set, defaults to 755 for directories and 644 for files.

    The third parameter, <path> could be used to specify a path while
    different to current directory.
