horrible bash script I wrote to find all domains with the format "ia######.us.archive.org" via brute force. first five "until" statements can be uncommented for surety. requires bash and curl

find_us_ia_domains.sh

#!/usr/bin/env bash
# find domains with format ia######.us.archive.org
# CC0 Public Domain
# https://gist.github.com/gabldotink/02076e1c66935de876f6a59ac1cd16e7

unset n
declare -i n='0'

printf 'looking for domains\n' >&2

#until [[ "${n}" -gt 9 ]]; do
#	if curl -s https://ia00000"${n}".us.archive.org &> /dev/null; then
#		printf 'https://ia00000%d.us.archive.org\n' "${n}"
#	fi
#	declare -i n="${n}+1"
#done

#until [[ "${n}" -gt 99 ]]; do
