72 option is specified, all symbolic links are followed.
76 option is specified, no symbolic links are followed.
79 Change the user ID and/or the group ID for the file hierarchies rooted
80 in the files instead of just the files themselves.
82 Don't report any failure to change file owner or group, nor modify
