Grab the main page with all the links:
curl https://slackmojis.com/ > emoji
Open file in vim and run the following commands:
v/src=/d
%s/^.*https:/https:/g"
%s/?.*$//g
This deletes any line that doesn't contain src=, deletes everything before https:, and deletes anything after ?.
Now loop over each URL and download the image:
while read url; do
curl -O $url;
done <./emoji
Install Slack Emoji Tools Chrome extension.
Drag all your emoji into the bulk upload box and then flip your machine over and fry some 🥓, cuz it's gonna get hot!
