A quick awk thing I wrote to strip out dead links for images from Jekyll posts

strip_old_images.sh

#!/bin/bash
rm -rf /var/tmp/cleaned_posts
mkdir -p /var/tmp/cleaned_posts
while read -r post ; do
  awk '/image:/ { our_image=$2 } /<img class/ { print "![For the Cure of Text](" our_image ")";next } { print $0 }' "$post" > /var/tmp/cleaned_posts/"$post"
done <<< "$(find . -name "*.md")"
