 * 主从切换后数据不一致的修复
 
 ```bash
 1. 取出老master额外的事务；
-    python binlog2sql.py --popPk --host='10.1.1.1' -P3306 -uadmin -p'admin' --stBinFile='mysql-bin.000002' --stBinStPos=1240 > oldMaster.sql
+    python binlog2sql.py --popPk --host='10.1.1.1' -P3306 -uadmin -p'admin' --start-file='mysql-bin.000002' --start-pos=1240 > oldMaster.sql
 2. 回滚老master额外的事务；
-    python binlog2sql.py --flashback --host='10.1.1.1' -P3306 -uadmin -p'admin' --stBinFile='mysql-bin.000002' --stBinStPos=1240 | mysql -h10.1.1.1 -P3306 -uadmin -p'admin'
+    python binlog2sql.py --flashback --host='10.1.1.1' -P3306 -uadmin -p'admin' --start-file='mysql-bin.000002' --start-pos=1240 | mysql -h10.1.1.1 -P3306 -uadmin -p'admin'
 3. 在新master重新执行事务；
     mysql -h10.1.1.2 -P3306 -uadmin -p'admin' < oldMaster.sql
