awk

Hi above floor,

Your code is so cute. I have never used it before. Thanks for your good idea.

Anyway, below is my solution using AWK.

code:
Code:
nawk 'BEGIN{OFS=FS="|"}
NR==FNR {t[$1]=$2}
NR!=FNR {$3=$2;$2=sprintf("%s",t[$1]);print}
' f1 f2

' f1 f2

Please give me the logic or explain me how it works.
Thanks

awk -F"|" 'NR==FNR {a[$1]=$2} NR!=FNR {print $0,"|",a[$1]}' f2 f1

Explanation:
------------

1) NR=FNR checks for the first file and stores the value of the second column from file "f2" in an array.
a[xx yy]=aaa
a[xx1 yy1]=bbb
a[xx2 yy2]=cccc

2) NR!=FNR checks for the second file and prints all the rows from second file along with the value of the column.

I hope this will be helpful.
