用shell提取一个文件中相同的行的计数

我这有一段httpd_access.log日志，想要提取当中同一IP访问同一连接，每分钟小于10次就OK，大于10次就high，日志格式如下：

10.238.0.161 - - [12/Feb/2014:16:31:59 +0800] "POST /cgi-bin/online/period_reports_cy.cgi HTTP/1.1" 200 562341
10.238.144.232 - - [12/Feb/2014:16:32:20 +0800] "GET /online.html HTTP/1.1" 304 -
10.238.144.232 - - [12/Feb/2014:16:32:20 +0800] "GET /css/online.css HTTP/1.1" 304 -
10.238.144.232 - - [12/Feb/2014:16:32:20 +0800] "GET /cgi-bin/online/cp9_condition.cgi HTTP/1.1" 200 7702
10.238.144.232 - - [12/Feb/2014:16:32:20 +0800] "GET /images/bkglobe1.gif HTTP/1.1" 304 -

Answer 1

使用awk来处理，会更方便，可以先过滤处理访问页面，然后遍历IP

Answer 2

IP就是每行最前面的一个字段喽
但是，访问同一连接如何看？
