bash script multiple rsync after previous has finished

hi i want to create a backup rsync script, and i want to create a additional copy of the sate of one folder at the beginning of the month and compare the changes to the end of the month my questing: ho can i run a rsync job after the previous has finished, so i don't delete the backup dir bevor i compared the changes and backed them up?

for now if have:

if [ $MONTH -eq 1] && [ $DAY -eq 1]; then
rsync -a --forece --ignore-errors --compare-des=$MONTH_COMPARE $EXCLUDE_STRING $SOURCE_LOC ssh $TARGET_DIR/$LASTYEAR/12 
rsync -a --forece --ignore-errors --delete --update $EXCLUDE_STRING $SOURCE_LOC ssh $MONTH_COMPARE

it is important, that the second you doesn't start bevor the fist one has finished

Delimine both rsync commands with && operator. This operator ensures, that the second command executes only if the fist one is finished succesfully (returns exit code 0).

So, your code will be 

if [ $MONTH -eq 1] && [ $DAY -eq 1]; then
rsync -a --forece --ignore-errors --compare-des=$MONTH_COMPARE $EXCLUDE_STRING $SOURCE_LOC ssh $TARGET_DIR/$LASTYEAR/12 &&
rsync -a --forece --ignore-errors --delete --update $EXCLUDE_STRING $SOURCE_LOC ssh $MONTH_COMPARE

You can also put those rsync lines into standalone script and launch it with cron on desired time, so you would not need the date condition.
