utility modifies the file flags of the listed files

The options are as follows:
63
option is specified, symbolic links on the command line are followed.
64
(Symbolic links encountered in the tree traversal are not followed.)
68
option is specified, all symbolic links are followed.
72
option is specified, no symbolic links are followed.
74
Change the file flags for the file hierarchies rooted
75
in the files instead of just the files themselves.
79
or a file encountered during directory traversal is a symbolic link,
80
the file flags of the link itself is changed.
83
Flags are a comma separated list of keywords.
84
The following keywords are currently defined:
85
.Bd -literal -offset indent -compact
86
arch set the archived flag (super-user only)
87
opaque set the opaque flag (owner or super-user only)
88
nodump set the nodump flag (owner or super-user only)
89
sappnd set the system append-only flag (super-user only)
90
schg set the system immutable flag (super-user only)
91
uappnd set the user append-only flag (owner or super-user only)
92
uchg set the user immutable flag (owner or super-user only)
