Why do you think you are doing something wrong? Please provide a small sample of your input file, the corresponding output, and what you expect the output to be.

When I run your code with my own input, the output I get is the line number plus 1 of the lines which just contain 1\n. To get the actual line number: 

$linenumber=1;
foreach $line(@fileData) {
   if ($line =~ m/^1$/) {
       print "$linenumber\n";
   }
   $linenumber++;
}

Update: You could also use the special variable $. instead of $linenumber

tinita is more precise. $. is used with filehandles.
