cat 配合awk筛选文件中某一列

cat 文件名 |awk -F'按照什么切分' '显示内容'
cat /home/presslogs/mhp-swagger/access_log.2020-01-22.log |awk -F' ' '{print $7}'
xxx.xxx.xxx.xx - - [22/Jan/2020:15:08:12 +0800] "POST /cfg/service/getHosParam HTTP/1.1" 200 209

按照空格切分后分成如下几部分

>xxx.xxx.xxx.xx
>-
>-
>[22/Jan/2020:15:08:12
>+0800]
>"POST
>/cfg/service/getHosParam
>HTTP/1.1"
>200
>209

cat配合awk、sort、uniq做数据统计

cat 文件名 |awk -F'按照什么切分' '显示内容'

sort 排序指令

uniq 可检查文本文件中重复出现的行列

cat /home/presslogs/mhp-swagger/access_log.2020-01-22.log |awk -F' ' '{print $7}'|sort -n|uniq -c|sort -nr

cat配合grep、awk、sort、uniq做数据统计

cat 文件名 |grep word|awk -F'按照什么切分' '显示内容'

grep 过滤

sort 排序指令

uniq 可检查文本文件中重复出现的行列

cat /home/presslogs/mhp-swagger/access_log.2020-01-22.log |grep Enum|awk -F' ' '{print $7}'|sort -n|uniq -c|sort -nr
