You also need to edit the log4php.properties file to enable debug 
logging; change where it says "FATAL" to "DEBUG".

It's probably not something I would recommend unless you know what you 
are doing or have lots of time to play, test & fail ;-) It's a thing 
I've been working on (on and off) since 2015 according to my git commit 
history ;-)

Anyway - basically you need to do this:

Depending on the process (New Installation, or a Migration) you need to 
set the VTIGER_UPGRADE and/or INSTALLATION_MODE constants. You need 
include a few files at the top such as the config.php and the WebbUI.php 
so the class loader works. Then it is helpful, but not essential, to 
edit the scripts so the output is readable on the cli as most of it is 
echoed with html tags such as br, p etc... I also turn on php 
error_reporting as this can be a lot more helpful than the debug logs.

You also really have to run the scripts as the web-server user because 
they need write access to the vtiger filesystem... I would never 
recommend using a super user account. FWIW on linux I create a 
.bash_alias entry for this

alias phpwww='sudo -u www-data php'

so from the command line I just need to type

# phpwww file-to-run.php

Hope that helps
