+.Sh DESCRIPTION
+The
+.Nm
+utility changes the user ID and/or the group ID of the specified files.
+Symbolic links named by arguments are silently left unchanged unless
+.Fl h
+is used.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl H
+If the
+.Fl R
+option is specified, symbolic links on the command line are followed.
+(Symbolic links encountered in the tree traversal are not followed.)
+.It Fl L
+If the
+.Fl R
+option is specified, all symbolic links are followed.
+.It Fl P
+If the
+.Fl R
+option is specified, no symbolic links are followed.
+This is the default.
+.It Fl R
+Change the user ID and/or the group ID of the specified directory trees
+(recursively, including their contents) and files.
+Beware of unintentionally matching the
+.Dq Pa ".."
+hard link to the parent directory when using wildcards like
+.Dq Li ".*" .
+.It Fl f
+Do not report any failure to change file owner or group, nor modify
+the exit status to reflect such failures.
+.It Fl h
+If the file is a symbolic link, change the user ID and/or the
+group ID of the link itself.
+.It Fl v
+Cause
+.Nm
+to be verbose, showing files as the owner is modified.
+If the
+.Fl v
+flag is specified more than once,
+.Nm
+will print the filename, followed by the old and new numeric user/group ID.
+.It Fl x
+File system mount points are not traversed.
+.El
+.Pp
+The
+.Fl H ,
+.Fl L
+and
+.Fl P
+options are ignored unless the
+.Fl R
+option is specified.
+In addition, these options override each other and the
+command's actions are determined by the last one specified.
+.Pp
+The
+.Ar owner
+and
+.Ar group
+operands are both optional, however, one must be specified.
+If the
+.Ar group
+operand is specified, it must be preceded by a colon (``:'') character.
+.Pp
+The
+.Ar owner
+may be either a numeric user ID or a user name.
+If a user name is also a numeric user ID, the operand is used as a
+user name.
+The
+.Ar group
+may be either a numeric group ID or a group name.
+If a group name is also a numeric group ID, the operand is used as a
+group name.
+.Pp
+The ownership of a file may only be altered by a super-user for
+obvious security reasons.
+.Sh EXIT STATUS
+.Ex -std
+.Sh COMPATIBILITY
+Previous versions of the
+.Nm
+utility used the dot (``.'') character to distinguish the group name.
+This has been changed to be a colon (``:'') character so that user and
+group names may contain the dot character.
+.Pp
+On previous versions of this system, symbolic links did not have
+owners.
+.Pp
+The
+.Fl v
+and
+.Fl x
+options are non-standard and their use in scripts is not recommended.

+.St -p1003.2
+compliant.
