Is there an easy way to poll (monitor) a directory, to see if any new folders have been created in it?

There might be an easier way that I'm overlooking but you could do it in a fairly primitive fashion like this...

ls -l someDirectory > originalDirectoryStatus
while :; do
sleep 600
ls -l someDirectory > newDirectoryStatus
diff originalDirectoryStatus newDirectoryStatus > directoryStatusInfo || DO_STUFF_WITH_STATUS_INFO
mv newDirectoryStatus originalDirectoryStatus
done
