The

|
||||||
|
.Ar file
|
||||||
|

|
.Ar group
|
||||||
|
ID specified by the group operand,
|
||||||
|
or to the group of the given
|
||||||
|
.Ar rfile ,
|
||||||
|
specified by the
|
||||||
|
.Fl Fl reference
|
||||||
|
argument.

.Pp
|
||||||
|
Options:
|
||||||
|

|
||||||
|
.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
|
||||||
|

|
||||||
|
is a symbolic link, the group of the link is changed.

is not given, unless the
|

|
or

|
option is set,
|

|
||||||
|
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 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.
|
||||||
|
.Pp
|
||||||

The
|
||||||
|

In addition, these options override each other and the

The

The

.Ar owner

|
and
|
||||||
|
.Ar group
|
||||||
|
operands are both optional, however, one must be specified; alternatively,

both the owner and group may be specified using a reference
|
||||||
|
.Ar rfile
|
||||||
|
specified using the
|
||||||
|
.Fl Fl reference
|
||||||
|
argument.
|
||||||
|
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
|
||||||
|
doesn't 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

|

|
.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,

|

|
.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.
