Sets National Geographic's Image of the Day as Desktop background for Mac OSX

set_NatGeo_img_as_desktop.sh

#!/usr/bin/env bash

cd ~/Pictures/NatGeo || exit 1

today="$(date +%Y-%m-%d)"
hostname="https://yourshot.nationalgeographic.com"
originalUrl="$(curl -s https://www.nationalgeographic.com/photography/photo-of-the-day/_jcr_content/.gallery.json | jq -r '.items[0].originalUrl')"
fullPhotoUrl="${hostname}${originalUrl}"

curl -s "$fullPhotoUrl" -o "national-geographic-photo-of-the-day_${today}.jpg"

# Set desktop background to image
sqlite3 ~/Library/Application\ Support/Dock/desktoppicture.db \
"update data set value = '~/Pictures/NatGeo/national-geographic-photo-of-the-day_${today}.jpg'"

killall Dock

Updated to parse the JSON rather than grep the html source, that method was broken and this is far easier to manage. Also latest MacOS seems to require a killall Dock to actually reload the displayed picture.

And passes shellcheck!
