PerlMonks, I have simple regular expression question for you. I am reading a file and if a line starts with the number 1, I want to write that line to a file. The problem is that if that file starts with 1, 11, 12, etc. those lines get written that file too. My regular expressions is like this: 
if (/^1/) {
    print FILE, "$_\n";
}

Is there a way to make my regex more stringent so I don't get lines in my file I don't want? Thank you.
