Thanks for noticing, but I have deliberately undocumented those short-named options because they are slated to be used differently in a future release: for link-traversal control, as is already done in many other tools, e.g., find, cp, du: $ cp --help|grep -e '-[LHP]' -H follow command-line symbolic links in SOURCE -L, --dereference always follow symbolic links in SOURCE -P, --no-dereference never follow symbolic links in SOURCE
