Description David Wood 2005-02-24 17:21:00 UTC
When using rsync with "--dry-run --stats" the reported "Number of files
transferred" and "Total transferred file size" are incorrect:

bsqa1.nyc:/tmp/rsync/test #  /tmp/rsync/bin/rsync --archive --dry-run --stats
/tmp/rsync/ bsprod1:/tmp/rsync/
building file list ... done

Number of files: 10
Number of files transferred: 3
Total file size: 853173 bytes
Total transferred file size: 126433 bytes
Literal data: 0 bytes
Matched data: 0 bytes
File list size: 188
File list generation time: 0.001 seconds
File list transfer time: 0.000 seconds
Total bytes sent: 254
Total bytes received: 74

sent 254 bytes  received 74 bytes  656.00 bytes/sec
total size is 853173  speedup is 2601.14

Notice that rsync reported that 3 files were transferred and they had a size of
126433 bytes.  Rsync was run with "--dry-run" so in fact 0 files were
transferred with 0 size.  I'll attach a patch I've been using to work around
this problem.  David

The purpose of the --dry-run is to tell you what would be transferred.  The
output of the names is exactly that: the file being mentioned normally means
"this file has been transferred", but with --dry-run it instead means "this file
would be transferred".  The stats follow in this same vein:  how many files
would have been transferred and how large are they?
