Here are some Magento 2.x CLI commands I use once in a while. Using this as my personal notepad, so to speak; might be useful for someone.

List all installed modules/extensions including version:

n98-magerun2 dev:module:list

Magento 2 list all modules:

php bin/magento module:status

Magento 2 set Varnish to flush with Magento FPC flush:

php bin/magento setup:config:set --http-cache-hosts=127.0.0.1

Check on CLI if Varnish is flushed when clicking button in Admin:

varnishlog -g request -q 'ReqMethod eq "PURGE"'

List Varnish URLs with most Cache Misses

This will create a list of the URLs that caused the most cache misses the last hour.

varnishtop -p 3600 -i BereqURL
