From 279d3ae95e139c2f9ffe4a28886117d868d4d5e5 Mon Sep 17 00:00:00 2001

Subject: (cp invocation): `cp --no-dereference' is no longer equivalent to `cp
 -d'. `cp -d' is equivalent to `--no-dereference --preserve=links'. cp's -P
 option means --no-dereference, not --parents. Describe new optional argument
 to --preserve. Describe new option: --no-preserve=ATTRIBUTE_LIST.

 @cindex file information, preserving
-Preserve the original files' owner, group, permissions, and timestamps.
+Preserve the specified attributes of the original files.
+If specified, the @var{attribute_list} must be a comma-separated list
+of one or more of the following strings:
+
+@table @samp
+@itemx mode
+Preserve the permission attributes.
+@itemx ownership
+Preserve the owner and group.  On most modern systems,
+only the super-user may change the owner of a file, and regular users
+may preserve the group ownership of a file only if they happen to be
+a member of the desired group.
+@itemx timestamps
+Preserve the times of last access and last modification.
+@itemx links
+Preserve in the destination files
+any links between corresponding source files.
+@c Give examples illustrating how hard links are preserved.
+@c Also, show how soft links map to hard links with -L and -H.
+@itemx all
+Preserve all file attributes.
+Equivalent to specifying all of the above.

+Using @option{--preserve} with no @var{attribute_list} is equivalent

 In the absence of this option, each destination file is created with the
 permissions of the corresponding source file, minus the bits set in the
 umask and minus the set-user-id and set-group-id bits. @xref{File permissions}.
