  -s ORDER     what to sort by (al, at, ar, c, l, r, t), 'at' is default（排序方式）
                 al: average lock time（平均锁定时间）
                 ar: average rows sent（平均返回记录数）
                 at: average query time（平均查询时间）
                  c: count（访问计数）
                  l: lock time（锁定时间）
                  r: rows sent（返回记录）
                  t: query time（查询时间）
   -r           reverse the sort order (largest last instead of first)
   -t NUM       just show the top n queries（返回前面n条数据）
   -a           don't abstract all numbers to N and strings to 'S'

                default is '*', i.e. match all
   -i NAME      name of server instance (if using mysql.server startup script)
   -l           don't subtract lock time from total time
