情况
我有 awk 命令从 mywebsite.log 当前命令读取结果
awk 'BEGIN{ curr_d=strftime("%d/%b/%Y", systime()) }
$3~"^\\["curr_d{ cc[$8]++ }
END{ for(i in cc) print i":"cc[i] }' /var/log/mywebsite.log > /home/mywebsite/www/countries.txt
仅提取国家代码并计算国家代码，然后导出到 countries.txt 如下，仅用于从 linux 获取当天的同一天的记录。
IN:35
US:123
QA:3
RU:23
MA:23
所需输出:
我只想获取访问量最大的 20 个 IP 地址，并计算这些 IP 地址在同一天访问的次数。与 Linux 日期（今天）匹配的日期然后保存到countries2.txt

对于您的附加条件“我想对国家/地区前缀后面的 IP 地址最后一位数字进行排序，例如 IN:20”：
删除该行if (++c==20) break并将其添加| sort -t: -k2nr | head -n20到命令末尾。
答案2
#!/bin/bash
i=`date +%d/%b/%Y -d "1 days ago"`
awk -v i="$i" '$3~i {print $1,$NF}' /tmp/l.txt >/tmp/ToTAL_VISITED_SITES
awk -v i="$i" '$3~i {print $1}' /tmp/l.txt| sort | uniq >/tmp/Sorted_Ips.txt
while read line1; do grep $line1 ToTAL_VISITED_SITES | uniq -c;done <Sorted_Ips.txt
/tmp/l.txt 包含输入文件。从上面的脚本提供了今天访问的各个站点的计数。如果您需要前 20 个站点，请使用以下命令：
sh scriptname | sort -nr| head -20
它对我来说效果很好。
