permissions:

...
      r    Read bits.
      s    Set-user-ID and set-group-ID on execution bits.
      t    Sticky bit.
      w    Write bits.
      x    Execute/search bits.
      X    The execute/search bits if the file is a directory or any
          of the execute/search bits are set in the original (unmodi-
          fied) mode. Operations with the perm symbol `X' are only
          meaningful in conjunction with the op symbol `+', and are
          ignored in all other cases.
      u    User permission bits in the mode of the original file.
      g    Group permission bits in the mode of the original file.
      o    Other permission bits in the mode of the original file.

      arch  set the archived flag
      opaque set the opaque flag (owner or superuser only)
