Re^3: Merge the difference between two files and save it on the first file. Also update the first file with info in second file.

when I wrote that, the author didnt clarify
the tasks clearly yet
if he needs select the name before "="
i would go with code:

%hash = map {/=(\w+)/; $` => $1} <DATA>;

foreach (sort keys %hash){
        print "$_ $hash{$_}\n";
}


__DATA__
A=hello
B=world
B=planet
C=universe
