Apache 日志分析shell脚本
查看access.log文件访问的状态码：
[root@localhost logs]# cat access.log | awk -F '" ' '{print $2}'|cut-d " " -f 1| awk '{++S[$1]} END {for (key in S) print S[key],key}'
6181 200

1、查看当天有多少个IP访问：
awk '{print $1}' |sort|uniq|wc -l
2、查看某一个页面被访问的次数：
grep "/index.php" | wc -l
3、查看每一个IP访问了多少个页面：
awk '{++S[$1]} END {for (a in S) print a,S[a]}'
4、将每个IP访问的页面数进行从大到小排序并显示前10名：
awk '{++S[$1]} END {for (a in S) print S[a],a}' | sort -rn | head -10
5、查看某一个IP访问了哪些页面：
grep ^111.111.111.111 | awk '{print $1,$7}'
6、去掉搜索引擎统计当天的页面：
awk '{print $12,$1}' | grep ^\"Mozilla | awk '{print $2}' |sort | uniq | wc -l
7、查看2009年6月21日14时这一个小时内有多少IP访问:
awk '{print $4,$1}' | grep 21/Jun/2009:14 | awk '{print $2}'| sort | uniq | wc -l
