你有两列数 分别在两个文件里面
现在你用其中一列去乘另外一列

前提是
第一列的第一个数 乘以 第二列的 5个数
第一列的第二个数 乘以 第二列的 6-10 个数

以此类推， 不要求计算结果，只要求能写出循环就可以了

awk 'BEGIN{i=1}NR==FNR{a[NR]=$0;next}{print a[i]"*"$0}!(FNR%5){i++}' a b

awk 'BEGIN{i=1}NR==FNR{a[NR]=$0;next}{print a[i]"*"$0"="a[i]*$0}!(FNR%5){i++}

' a b    //打印出结果

我现在需要统计出每个小时登入登出的id数

第三列是玩家id，in是登入，out是登出

awk -F"[:|]" '{b[$1]=$4;if(!a[$1]){a[$1]=$1;if(b[$1]=="in"){i[$1]=1}else{j[$1]=1}}else{if(b[$1]=="in"){i[$1]++}else{j[$1]++}}}END{for(z in a){print a[z],"in",i[z],"out",j[z]}}' test.txt
