.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
utility sets the group ID of the file named by each
|
||||
.Ar file
|
||||
operand to the
|
||||
.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:
|
||||
.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.
|
||||
.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
|
||||
.Nm
|
||||
utility exits 0 on success, and \*[Gt]0 if an error occurs.
|
||||

.Sh DESCRIPTION
|
||||
.Nm
|
||||
sets the user ID and/or the group ID of the specified files.
|
||||
.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.
|
||||
.It Fl R
|
||||
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
|
||||
Don't 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.
|
||||
.Pp
|
||||
The
|
||||
.Fl L
|
||||
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; 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
|
||||
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.
|
||||
.Pp
|
||||
The
|
||||
.Nm
|
||||
utility exits 0 on success, and \*[Gt]0 if an error occurs.
|
||||
.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.
