utility modifies the file flags of the listed files
The options are as follows:
When encountering a symbolic link on the command line, follow it. All other
symbolic links encountered in the traversal are not followed.
Traverse a file hierarchy.
For each file that is of type directory,
changes the flags of all files in the file hierarchy below it followed
by the flags of the directory itself.
When encountering a symbolic link anywhere in the traversal, follow it.
The flags of a symbolic link are immutable, so that unless the
on a symbolic link is a no-op.
Only the owner of a file or the super-user is permitted to change
the low 16-bits in the flags of a file.
Only the the super-user is permitted to change
the high 16-bits in the flags of a file.
utility exits 0 on success, and >0 if an error occurs.
Flags may be absolute or symbolic.
An absolute flag is an octal number constructed by
.Bl -tag -width 6n -compact -offset indent
the file should never be dumped
The symbolic flags is a comma separated list of keywords.
The following keywords are defined:
.Bd -literal -offset indent
dump cause the file to be dumped when it is next modified
Putting the word ``no'' before an option causes it to be deleted.
.Bd -literal -offset indent
nodump the file should never be dumped
