yeeeah..! Fine.. I understood.,

So the problem is not with the matching and with the substitution.

Thanks..!

    Yes.

    There's no need at all to change the original string to extract the data you want. All you need is to match it.

    if($line =~ /^(\S+\s+\S+)/) { $match = $1; }
    or even simpler:
    ($match) = $line =~ /^(\S+\s+\S+)/;
    Note that for the latter, the assignment must be in list context, not scalar context; that's what the parens around the variable on the left hand side are for.
