rsync parameters errors

[Joe]

I added eval and the backslash.  No joy.

What does work, but shouldn't be necessary was using a subshell to force
rsync onto a lower parameter diet:

COMMAND="(rsync ${DRY_RUN} -avushi ${DELETE} --stats --progress
--log-file=${LOGFILE1} ${MOUNT_POINT[0]}/${DIRECTORY[0]}/
${MOUNT_POINT[1]}/${DIRECTORY[1]}) | tee ${LOGFILE2} 2>&1"
echo "RUNNING [[${COMMAND}]]" ## let user see what's being done
eval ${COMMAND}                    ## Do it!

I'll see if any of the newer comments shed any further light on this.
