Hi Folks,

Here is a question for which I have not quite found the most efficient solution in the books at my disposal. What I want to do is read in a file at the command line and add an underscore to each line in the file. As an advanced case I would like to do this for every line except the first. I can print to STDOUT using the following code 
while (<>){
    chomp $_;
    $newline = $_ . "_";
    print $newline;
    print "\n";
}

This prints out each line to STDOUT. I can redirect the output to a newfile, but what I want to do is overwrite the original file. What would be the most efficient way to do this? Of course I have the more advanced case where I do not want to touch line #1. As far as I can figure out I need a way to bybass $_[0] and only modify after that but am not quite sure how to do it

Thanks
