[Powershell Basics] Find substring in string array

Imagine that you have array of strings (email addresses for example):

one-domain.ru
two-domain.ru
three-domain.com
four-domain.com
five-domain-company.com

You have a task - find email addresses in domain domain.ru among these strings.

You can solve this in the following way:

PS H:\> $array
one-domain.ru
two-domain.ru
three-domain.com
four-domain.com
five-domain-company.com
PS H:\>
PS H:\> $array -like "*domain.ru*"
one-domain.ru
two-domain.ru
PS H:\>

How can you use that?

Such trick can be used when you need to find Exchange users which have e-mail addresses in some specific domain.

Imagine now that you have array of arrays. You can encounter this when you run Get-MailBox. In this case search command will look like this:

Get-Mailbox | %{$_.emailaddresses -like "*domain.ru*"}

Thats it.
