awk統計獨立IP

awk文件形式

-----------ip.awk----------

{

        ip[$1]++
}
END {
        for(i in ip)
        {
                print i,ip[i] >"/tmp/ip.txt"
        }

}

awk -f ip.awk /usr/local/apache/logs/access_log

非awk文件形式：

1、awk '{ip[$1]++} END{for(i in ip){print i,ip[i]}}' /usr/local/apache/logs/access_log

2、cat /usr/local/apache/logs/access_log |awk '{print $1}'|sort -n |uniq -c
