.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 indent
|
|
.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 file flags for the file hierarchies rooted
|
|
in the files instead of just the files themselves.
|
|
.El
|
|
.Pp
|
|
The flags are specified as an octal number or a comma separated list
|
|
of keywords.
|
|
The following keywords are currently defined:
|
|
.Pp
|
|
.Bl -tag -offset indent -width "opaque" -compact
|
|
.It Ar arch
|
|
set the archived flag (super-user only)
|
|
.It Ar opaque
|
|
set the opaque flag (owner or super-user only)
|
|
.It Ar nodump
|
|
set the nodump flag (owner or super-user only)
|
|
.It Ar sappnd
|
|
set the system append-only flag (super-user only)
|
|
.It Ar schg
|
|
set the system immutable flag (super-user only)
|
|
.It Ar sunlnk
|
|
set the system undeletable flag (super-user only)
|
|
.It Ar uappnd
|
|
set the user append-only flag (owner or super-user only)
|
|
.It Ar uchg
|
|
set the user immutable flag (owner or super-user only)
|
|
.It Ar uunlnk
|
|
set the user undeletable flag (owner or super-user only)
|
|
.It Ar archived , sappend , schange , Xo
|
|
.Ar simmutable , uappend , uchange , uimmutable ,
|
|
.Ar sunlink , uunlink
|
|
.Xc
|
|
aliases for the above
|
|
.El
|
|
.Pp
|
|
Putting the letters
|
|
.Dq Ar no
|
|
before an option causes the flag to be turned off.
|
|
For example:
|
|
.Bl -tag -offset indent -width "nouchg"
|
|
.It Ar nouchg
|
|
the immutable bit should be cleared
|
|
.El
|
|
.Pp
|
|
Symbolic links do not have flags, so 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
|
|
You can use "ls -lo" to see the flags of existing files.
|
|
.Sh DIAGNOSTICS
|
|
The
|
|
.Nm
|
|
utility exits 0 on success, and >0 if an error occurs.
