Hi, I am trying to open file and replace a line for string matching. my code looks like 
open(my $FileH,"+<$meterFile"){
        while (<$FileH>) {
            if ($_ =~ /sdpRowId:(.*)/){
                #print "$_ \t $rowId\n";
                $_ =~ s/sdpRowId:(.*)/sdpRowId: <ReplaceString>/g;
                print $FileH $_;
            }
        }
        close($FileH);

above code is appending the non-matching lines also in same file, i just want to search and replace same line.
