.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility modifies the file flags of the listed files
|
|
as specified by the
|
|
.Ar flags
|
|
operand.
|
|
.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 file flags for the file hierarchies rooted
|
|
in the
|
|
.Ar files
|
|
instead of just the
|
|
.Ar files
|
|
themselves.
|
|
.It Fl h
|
|
If the
|
|
.Ar file
|
|
or a file encountered during directory traversal is a symbolic link,
|
|
the file flags of the link itself is changed.
|
|
.El
|
|
.Pp
|
|
Flags are a comma separated list of keywords.
|
|
The following keywords are currently defined:
|
|
.Bl -column -offset indent "Keyword " "system append-only" "Permission"
|
|
.It Sy Keyword Ta Sy Flag Ta Sy Permission
|
|
.It Em arch Ta archived Ta super-user only
|
|
.It Em opaque Ta opaque Ta owner or super-user
|
|
.It Em nodump Ta nodump Ta owner or super-user
|
|
.It Em sappnd Ta system append-only Ta super-user only
|
|
.It Em schg Ta system immutable Ta super-user only
|
|
.It Em uappnd Ta user append-only Ta owner or super-user
|
|
.It Em uchg Ta user immutable Ta owner or super-user
|
|
.El
|
|
.Pp
|
|
Putting the letters
|
|
.Dq no
|
|
before an option causes the flag to be turned off.
|
|
For example:
|
|
.Pp
|
|
.Bl -tag -offset indent -width ".Em nouchg"
|
|
.It Em nouchg
|
|
the immutable bit should be cleared
|
|
.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 o
|
|
option
|
|
of
|
|
.Xr ls 1
|
|
is used to display the flags.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility exits 0 on success, and \*[Gt]0 if an error occurs.
|
|
.Pp
|
|
The kernel does not allow the flags on block and character
|
|
devices to be changed except by the super-user.
