Cut and paste error.  Corrected full instructions:

  tcpclient -HRl0 199.166.24.1 53 axfr-get . root.raw root.raw.tmp
  nawk '!x[$0]++' < root.raw > root.clean
  awk -F: '/^[&]/ { print $1 ; }' < root.clean \
       | sed -e 's/^.//' -e 's/\([^.]\)$/\1./' > top-level-domains

Alternative instructions (eliminating intermediate file, should such a file
not be otherwise needed, and Useless Use of "sed"):

  tcpclient -HRl0 199.166.24.1 53 axfr-get . root.raw root.raw.tmp
  nawk -F: < root.raw \
    '/^[&]/ { sub("^.","",$1) ; sub("[^.]$","&.",$1) ; print $1 ; }' \
       | nawk '!x[$0]++' > top-level-domains
