Broken in Ubuntu 20.04

This looks like it would be an awesome tool but it's output is broken for Ubuntu 20.04. For example:

===== Recommendations per pool ===== (standard_in) 1: syntax error (standard_in) 1: syntax error --- 134936920328761 --- Current usage: 1.20% Recommended max_children: (current: 5)Config file: /etc/php/5.6/fpm/pool.d/134936920328761.conf

curl -L https://raw.githubusercontent.com/pksteyn/php-fpmpal/master/php-fpmpal.sh | sed 's/phpfpm_installed=0/phpfpm_installed=1/' | sudo bash

I've used the above to temporarily suppress the exec (php-fpm) not being available in ubuntu-2204-lts

the exec is a launcher (/usr/lib/php/php-fpm-socket-helper) for a service that takes conf args. It does not provide a help menu or version and is not included in the PATH by default.

===== Recommendations per pool ===== (standard_in) 1: syntax error (standard_in) 1: syntax error -- www -- currently uses 15188 KB memory (100.00% of all PHP-FPM memory usage). It should be allowed to use about KB of all available memory. Its average process size is 7594 KB so this means max_children should be set to ~. It is currently set to 5 (this can be changed in /etc/php/8.3/fpm/pool.d/www.conf).

===== Other considerations to take into account ===== No other recommendations at this stage.

Note: It is not ideal to run PHP-FPMpal shortly after restarting PHP-FPM or your webservices. This is because PHP-FPMpal makes recommendations based on the average pool process size, and if PHP-FPM was restarted a short while ago then the likelihood is high that there won't have been many requests made to the sites since the restart, and metrics will be skewed and not show a normalised average. It is also worth noting that if you've recently restarted any services that normally use up a large amount of memory then you probably want to wait a while before running PHP-FPMpal (e.g. if MySQL normally uses 50% of memory, but you've just restarted it then it may only use 10% of memory right now, thus the recommendations will be very skewed).
