Double quotes are not magic in a regex, so you do not have to escape them.

If you want to skip the first line of your loop, why not simply do a <FILE> just before the loop? That reads the first line and discards it.

You do not need a chomp inside the loop. Your regex extracts the fields well before it reaches the end of the string.

Always use a three argument open. What do you think will happen when someone maliciously enters >myfile.txt as the filename argument? Indeed, bye bye file contents!
