我有两个文件:
文件1

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

文件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 }'

最佳答案

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

输出:
Jimmy|20000|90000|1800000000

使用Jimmies解释了一些:
$ 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
