I see this output. What does ">f.s........ 2.txt" mean? Thanks.

$ rsync -avun --delete --itemize-changes /tmp/tmp.GH6z0oN8rn/a/
/tmp/tmp.GH6z0oN8rn/b
sending incremental file list
>f.s........ 2.txt

sent 73 bytes  received 19 bytes  184.00 bytes/sec
total size is 4  speedup is 0.04 (DRY RUN)


==> /tmp/tmp.GH6z0oN8rn/a/1.txt <==
1

==> /tmp/tmp.GH6z0oN8rn/a/2.txt <==
2

==> /tmp/tmp.GH6z0oN8rn/b/1.txt <==
1

==> /tmp/tmp.GH6z0oN8rn/b/2.txt <==
