Jimmy|90000
Output : Jimmy|20000|90000|1800000000输出:吉米|20000|90000|1800000000
I've tried, but no luck.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 }'
Could you please try following. 您可以尝试以下吗?
awk -F'|' 'NR==FNR{a[$1]=$4; next} (($1 in a) && (a[$1] <= $2 )) {$(NF+1)=a[$1]*$2;$2=a[$1] OFS $2;print}' OFS="|" File1 File2
Output will be as follows. 输出如下。
Jimmy|20000|90000|1800000000
Another: 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
outputs: 输出:
Jimmy|20000|90000|1800000000
Explained some using Jimmies: 使用Jimmies进行了一些解释:
$ 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
