+The

+.Ar file

+.Ar group
+ID specified by the group operand.
+.Pp
+Options:
+.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.
+.It Fl R
+Change the group ID for the file hierarchies rooted
+in the files instead of just the files themselves.
+.It Fl f
+The force option ignores errors, except for usage errors and doesn't
+query about strange modes (unless the user does not have proper permissions).
+.It Fl h
+If
+.Ar file
+is a symbolic link, the group of the link is changed.
+.It Fl v
+Cause
+.Nm
+to be verbose, showing files as they are processed.
+.El
+.Pp
+If
+.Fl h
+is not given, unless the
+.Fl H
+or
+.Fl L
+option is set,
+.Nm
+on a symbolic link always succeeds and has no effect.
+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.
+The default is as if the
+.Fl P
+option had been specified.
+.Pp
+The
+.Ar group
+operand can be either a group name from the group database,
+or a numeric group ID.
+Since it is valid to have a group name that is numeric (and
+doesn't have the numeric ID that matches its name) the name lookup
+is always done first.
+Preceding the ID with a ``#'' character will force it to be taken
+as a number.
+.Pp
+The user invoking
+.Nm
+must belong to the specified group and be the owner of the file,
+or be the super-user.
+.Pp
+Unless invoked by the super-user,
+.Nm
+clears the set-user-id and set-group-id bits on a file to prevent
+accidental or mischievous creation of set-user-id or set-group-id
+programs.

+.Sh DESCRIPTION
+.Nm
+sets the user ID and/or the group ID of the specified files.

+.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.)

+Change the user ID and/or the group ID for the file hierarchies rooted
+in the files instead of just the files themselves.
+.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
+.Ar file
+is a symbolic link, the owner and/or group of the link is changed.
+.It Fl v
+Cause
+.Nm
+to be verbose, showing files as they are processed.
+.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.
+The default is as if the
+.Fl P
+option had been specified.
+.Pp
+The
+.Fl R
+option cannot be used together with the
+.Fl h
+option.
+.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 user name or a numeric user ID.
+The
+.Ar group
+may be either a group name or a numeric group ID.
+Since it is valid to have a user or group name that is numeric (and
+does not have the numeric ID that matches its name) the name lookup
+is always done first.
+Preceding an ID with a ``#'' character will force it to be taken
+as a number.
+.Pp
+The ownership of a file may only be altered by a super-user for
+obvious security reasons.
+.Pp
+Unless invoked by the super-user,
+.Nm
+clears the set-user-id and set-group-id bits on a file to prevent
+accidental or mischievous creation of set-user-id and set-group-id
+programs.
+.Sh EXIT STATUS
+.Ex -std chown
+.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.

+.Sh STANDARDS
+The
+.Nm
+command is specified by POSIX.1-2017.
+.Pp
+The
+.Fl v
+and

+options and the use of ``#'' to force a numeric lookup
+are extensions to
