for i in `ls`;do echo $i;done
for i in `ls`;do rm -rf $i;done

for i in {20190929,20190930,20191001,20191002,20191003,20191004,20191005,20191006,20191007,20191008,20191009,20191010,20191011};do cp -r /mnt/$i ./;done

for i in {20190929,20190930,20191001,20191002,20191003};do grep data_driver_balance_extend $i/oride.sql > $i/data_driver_balance_extend.$i;done

for i in {20191009,20191010,20191011}; do rm -rf $i;done
for i in {20191010,20191011};do cp -r /mnt/$i ./;done
