Hi,

I may be missing some thing here, why not just copy file B to file A?

Regards

Dave

Hello Nikhil,

Following may help you in same. Let's say we have files as follows.

FileA is as follows.
Code:
A=www.google.com
B=www.abcd.com
C=www.nick.com
D=567
E=umma.com
F=char.com

FileB is as follows.
Code:
A=www.google1234.com
B=www.bacd.com
C=www.mick.com
D=789
Q=queen

Then following may help you in same.

Code:
awk -F"=" 'FNR==NR{A[$1]=$2;next} ($1 in A){print $1 OFS A[$1]} !($1 in A){print $0}' FileA OFS="=" FileB

Output will be as follows.
Code:
A=www.google.com
B=www.abcd.com
C=www.nick.com
D=567
Q=queen

It will replace all the contents which are present in FileA but if any content from FileB is not present in FileA it will keep it as it is.

Hope this helps.


Thanks,
R. Singh

I'd guess he/she wants it more like
Code:
awk 'FNR==NR{R[$1]=$0;next} $1 in R {$0=R[$1]} 1' FS="=" OFS="=" file2 file1
A=www.google1234.com
B=www.bacd.com
C=www.mick.com
D=789
E=89000
F=www.sneh.com
