I'm relatively new to PowerShell and am trying to learn it for a project at work involving Active Directory. The task I have is to compare the members of two different security groups in AD (both groups are located in the same OU) and copy the members from Group 2 that are not in Group 1 over to Group 1. 

I came across [this link](http://ravingroo.com/1030/powershell-compare-membership-of-two-active-directory-groups/) that showed how to compare groups but:

1. The code segment listed on this website returns both the members from Group 1 that aren't in Group 2 and the members from Group 2 that aren't in Group 1 which is way more information than I need
2. Once I get the list I don't know how to use that to enter into a command or script to copy those members to the appropriate group.
