How to get the list of not found pages on nginx

Camilo Nova
CEOYou can get the list of not found pages (404) grouped by URL on nginx (ubuntu) running this command on the console:
sudo awk '($9 ~ /404/)' /var/log/nginx/access.log | awk '{print $7}' | sort | uniq -c | sort -rn
Useful when setting up redirections when you migrate to a new website.
