The stats come out on stderr, not stdout, so you'd need to do:

    curl -n $Source/access_log -o $Dest/access_log 2>> $Report

The problem with that approach is that the stats aren't just a simple line, as you'll see if you download a large file. The row of numbers is redrawn by issuing carriage-returns and rewriting it with the current figures, so your file will contain.

Check out the -w/--write-out option. You can turn off the progress meter and get whichever download stats you want in whatever order you want:

    curl -s -S -n $Source/access_log -o $Dest/access_log \
        -w "%{time_total},%{size_download},%{speed_download}\n" >> $Report

for example, to get the total time for the whole operation, the total bytes downloaded, and the verage speed of the download in a comma separated format.

The list archives seem to say that redirecting with the -o option does not affect the stats and they do not show up at the end of the actual downloads. I have tried piping stdout to a subsequent echo but that doesn't work either. If I run the script from a terminal the stats are printed there. I have also tried redirecting stderr with no luck.
