mysqlbinlog --no-defaults -vv --base64-output=DECODE-ROWS --start-datetime="$starttime" --stop-datetime="$endtime" $logname |sed -n '/### DELETE FROM `'${db}'`.`'${table}'`/,/COMMIT/p' | \
sed -n '/###/p' | \
sed 's/### //g;s/\/\*.*/,/g;s/DELETE FROM/INSERT INTO/g;s/WHERE/SELECT/g;' > $tmpfile

((n++));
done
sed -i -r "s/(@$n.*),/\1;/g" $tmpfile
sed -i 's/@.*=//g' $tmpfile
sed -i 's/@=//g' $tmpfile
# 用法：-b -s -e -d -t 分别带别binlog名字 开始的time 结束的time 库名 表名，
# 直接使用 sh del_time_recovery.sh -b /mysqllog/mysql-bin.000005 -s "2017-11-02 19:10:00" -e "2017-11-02 19:20:00" -d test_db -t test_tb 即可调用
