- -\b-k\bk The -\b-k\bk option requests r\brc\bcp\bp to obtain tickets for the remote
- host in realm _\br_\be_\ba_\bl_\bm instead of the remote host's realm as
- determined by krb_realmofhost(3).
+ -\b-p\bp The -\b-p\bp option causes r\brc\bcp\bp to attempt to preserve (duplicate) in its
+ copies the modification times and modes of the source files, ignor-
+ ing the _\bu_\bm_\ba_\bs_\bk. By default, the mode and owner of _\bf_\bi_\bl_\be_\b2 are pre-
+ served if it already existed; otherwise the mode of the source file
+ modified by the umask(2) on the destination host is used.
+
+ -\b-r\br If any of the source files are directories, r\brc\bcp\bp copies each subtree
+ rooted at that name; in this case the destination must be a direc-
+ tory.
+
+ -\b-x\bx The -\b-x\bx option turns on DES encryption for all data passed by r\brc\bcp\bp.
+ This may impact response time and CPU utilization, but provides in-
+ creased security.
