使用awk命令比较两个文件和算术文件

Question

我有两个档案：

档案1

*Name|Date|id|Total*
Jimmy|03-OCT-18|BST100114262|20000
Dedi|03-OCT-18|BST100904288|10000

档案2

*Name|Amount*
Anton|9800
Jimmy|90000

输出:吉米-20000/90000-1800000000

我试过了，但没有运气。

awk -F'|' 'NR==FNR{a[$1]=$1; next} (($1 in a) && (a[$4] >= $2 )) { print a[$4]*$2 }'

Answer 1

另一个：

$ awk 'BEGIN{FS=OFS="|"}($1 in a)&&FNR>1{print $1,a[$1],$NF,a[$1]* $NF}{a[$1]=$NF}' file1 file2

产出：

Jimmy|20000|90000|1800000000

解释了一些用金米：

$ awk '
BEGIN { FS=OFS="|" }               # set separators
($1 in a) && FNR>1 {               # if key to hash (Jimmy) is in a excluding headers
    print $1,a[$1],$NF,a[$1]* $NF  # process Jimmy
    # next                         # this excludes new Jimmy from being rehashed to a
}
{
    a[$1]=$NF                      # ... in here where everything is hashed and  the
}' file1 file2                     # ... existing rehashed
