1. 对目录进行排序

   ls | awk -v FS="Capture-" '{print $2}'|sort -n -t "-" -k 1
   ls | sort -n -t "-" -k 5

   FS 表示 awk 分隔符

-n 表示按照数字大小排序
-t 表示 sort 命令的分隔符
2. 显示独有的字符串

ls | awk -v FS="-" '{print $2}'|uniq -c

3. 查看标签类别个数

    cat CTU-IoT-Malware-Capture-1-1/bro/conn.log.labeled | awk '{print $23}'|sort|uniq -c

4. 筛选某一列为指定内容

   cat  CTU-IoT-Malware-Capture-43-1/bro/conn.log.labeled | awk  '{if($2==123) print $0}'
   
   awk '{print $23}' CTU-IoT-Malware-Capture-1-1/bro/conn.log.labeled |sort|uniq -c
   
   awk '{if($3=="192.168.1.198" && $4==36934) print $0}' CTU-IoT-Malware-Capture-1-1/bro/conn.log.labeled |sort|uniq -c
   
   awk  '{if($3=="192.168.1.198" && $4==36934) print $0}' CTU-IoT-Malware-Capture-43-1/bro/conn.log.labeled  # 多条件搜索
