Check if a user in group exists

[alexa...@gmail.com]

Hello!

I have hard coded for add a user in group. How to check by 'ifvarclass' (or any), that a user in group exist and don't run the command 'usermod'?

command:

  "/usr/sbin/usermod -a -G $(group_index)  $(user_index)";

Makes me think we could extend the userexists() function to take a group name as an optional
argument.

Without it, I think the best option is to use regline() on /etc/group.
