How can I manage groups and users from CLI?

[Sopalajo de Arrierez]

I would like to manage groups and its corresponding users from command-line on pfSense.

I have found this documentation:

https://docs.netgate.com/pfsense/en/latest/usermanager/users.html

... but it only refers to GUI.

What is the proper method to manage (add, delete... etc) groups (and, of course, add/delete users to/from those groups) on pfSense by using command-line?

[Gertjan]

pfSense is GUI based.

For most GUI options there is no direct CLI equivalent.

But, knowing that the GUI is 99,99 % script (PHP) driven, it's possible to make your own scripts.

Thanks you, Gertjan.

I tried:

pw groupadd GROUPNAME

But changes are deleted after rebooting.

pfSense users and groups is not what FreeBSD users and groups are.
They have some common grounds, true.
