# just wondering how I would skip the first line of a file?

then go, play w it using ruby ;-)

# File.open('file.txt', 'r').each do |line|
#  # start on the 2nd line
# end

as always, there are many ways (depennding on your taste), 

eg given a file,

File.open('file.txt', 'r').each do |line|
  p line
end
"1234\n"
"456\n"
"4321\n"
"654\n"
"546\n"
"3456\n"
"5436\n"
"9879\n"
"1111\n"
#=> #<File:file.txt>


you can skip the line by referring to it's index,

File.open('file.txt', 'r').each_with_index do |line,index|
  next if index == 0
  p line
end
"456\n"
"4321\n"
"654\n"
"546\n"
"3456\n"
"5436\n"
"9879\n"
"1111\n"

or just skip it by reading and discarding it

File.open('file.txt', 'r') do |file|
  file.readline
  file.each do |line|
    p line
  end
end
"456\n"
"4321\n"
"654\n"
"546\n"
"3456\n"
"5436\n"
"9879\n"
"1111\n"
#=> #<File:file.txt (closed)>

note i prefer the latter since its clearer (to me), and it does not annoy the loop ;)
