假设日志为：
    xxx.xxx.xxx.xxx - admin1 [10/Jan/2022:15:10:51 +0800] “GET /abc?p=tttt02%2FmybatisDemo.git;a=shortlog;h=refs%2Fheads%2Fbranchdiff-001;pg=0 HTTP/1.1” 302 138 “-“ “Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.130 Safari/537.36”

    1）统计有哪些ip访问了/login

    1. # cat  access.log|awk '{if ( $7 == "/login" ) {print $1}}'|sort|uniq
    2. 111.22.2.185
    3. 111.22.2.49
    4. 111.22.5.38
    5. 111.22.17.154

    2）统计一级url的访问次数

    1. # cat  access.log|awk '{print $7}'|awk -F '?' '{print $1}'|awk -F '/' '{print $1"/"$2}'|sort|uniq -c|sort -n
    2.       1 /t
    3.       1 /tood
    4.       1 /toos
    5.       7 /tools
    6.       8 /aaa

    3）查看某个url的日志

    1. cat  access.log|awk '{if ( $7 == "/login" ) {print $0}}'

    附注：
    uniq -c，去重并统计数量
    sort -n，按数字排序
