Powershell format-table or select-object only show top results - sorting

Question

I am trying to find users that have been sending the most emails.
But in the end I only want to display the top 10 (or n number) of senders.
Is there a way to only show the top results using select-object or format-table
$Messages = Get-ExchangeServer * | where{$_.ServerRole -eq "HubTransport"} | %{get-messagetrackinglog -server $_.name -EventID "SEND" -Start (get-date -format G).AddDays(-1) -ResultSize unlimited}) 2>&1 | out-null
$messages | where{$_.sender -like "*#OurDomain.com*"} | select sender | group sender | sort count -Descending | ft count,name
Is there a way to make this only display the top results?
The only way I can think of would be storing them in a variable and outputting them in a for loop

Answer 1

Before the ft, add:
select -first 10
Replacing the 10 with how many you want.
So the full command would be:
$messages | where{$_.sender -like "*#OurDomain.com*"} | select sender | group sender | sort count -Descending | select -first 10 | ft count,name

This is asked a long time ago. But I got surprised by one thing, that you were using select and didn't look at this thing. Well in case you are thinking this is a rude answer - no it won't be. The point is you were this close to the solution. So few days back (by the way I don't know powershell much) I was asked this question and I had to display things only the first few. So the first thing I did was get-help *display* thinking that it would somehow show me something which would let me display some stuff. I was wrong, and realized I need to look for something. Then I look for the action words or the verbs. I checked get-Verb and then I could see the verbs that are relevant.
And I found select. It sounds reasonable, and then I opened help for select. get-help select -ShowWindow. And I checked the parameters and found this
-First <Int32>
Gets only the specified number of objects. Enter the number of objects to get.
Required? false
Position? named
Default value False
Accept pipeline input? False
Accept wildcard characters? false
And that's it. I don't know anything about power shell but I guess this can still be found with some workout like this.
For you, you knew that it would be select so you could have easily checked the parameters to solve it. In fact even the examples on how to do stuff is helpful. For example right after discovering First I got this example which made me clear about the syntax.

Yes this can be first as well and I did that and got the result.

Note: The previous answer is awesome and showed everything that the OP needed. I am just showing my way of solving the same thing.
