Unintuitively, tail is the utility you want:

  $ tail -n +2 file

From tail(1):

  -n, --lines=K
    output the last K lines, instead of the last 10; or use -n +K to output lines starting with the Kth

Yeah, I know about that, I just prefer not to use that option because `head -1 > /dev/null` is clearer
