Bruce Evans 158562983e Yet another previously forgotten merge from Lite2. (Describe
`opaque', fix reversed description of `nodump', and don't use
`nodump' as an example of adding a `no' prefix since the double
negative would be confusing (it's still confusing -- the implicitly
documented `nonodump' flag doesn't exist).)

.Sh NAME
.Nm chflags
.Nd change file flags
.Sh SYNOPSIS
.Nm chflags
.Oo
.Fl R
.Op Fl H | Fl L | Fl P
.Oc
.Ar flags
.Ar file ...
.Sh DESCRIPTION
The
.Nm chflags
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 files instead of just the files themselves.
.El
.Pp
Flags are a comma separated list of keywords.
The following keywords are currently defined:
.Bd -literal -offset indent compact
arch set the archived flag (super-user only)
opaque set the opaque flag (owner or super-user only)
nodump set the nodump flag (owner or super-user only)
sappnd set the system append-only flag (super-user only)
schg set the system immutable flag (super-user only)
sunlnk set the system undeletable flag (super-user only)
uappnd set the user append-only flag (owner or super-user only)
uchg set the user immutable flag (owner or super-user only)
uunlnk set the user undeletable flag (owner or super-user only)
archived, sappend, schange, simmutable, uappend, uchange, uimmutable,
sunlink, uunlink
aliases for the above
.Ed
.Pp
Putting the letters
.Dq no
before an option causes the flag to be turned off.
For example:
.Bd -literal -offset indent compact
nouchg the immutable bit should be cleared
.Ed
.Pp
Symbolic links do not have flags, so unless the
.Fl H
or
.Fl L
option is set,
.Nm chflags
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.
.Pp
The
.Nm chflags
utility exits 0 on success, and >0 if an error occurs.
