#! /bin/bash
# NAME
# whatsnew - return URLs of resources that changed since the specified
# date
#
# SYNOPSIS
# whatsnew date
#
# STANDARD INPUT
# URLs to look for
#
# STANDARD OUTPUT
# Changed resources
set -e
ref_date="$(date -u -Iseconds -d "$1")"
# `read` tries to tokenize lines. But, since lines are URLs (should not contain
# spacing) and we use the (non-standard) `-r` option (disables meaning of
# backslashes), it does the job here.
while IFS='' read -r url || [[ -n "${url}" ]]; do
last_modified="$(curl -sI -- "${url}" | tr -d '\r' | sed -En 's/^Last-Modified: (.*)$/\1/Ip' | xargs -d '\n' -- date -u -Iseconds -d)"
if [ "${last_modified}" '>' "${ref_date}" ]; then
printf '%s\n' "${url}"
