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 From unknown Sun Jun 22 03:49:53 2025 Received: (at fakecontrol) by fakecontrolmessage; To: internal_control@debbugs.gnu.org From: Debbugs Internal Request Subject: Internal Control Message-Id: bug archived.
