I have an array $data :
PS> $data
Datum User Computer
----- --------- --------
10/06/2013 13:10:56 geb1@TESTDOMAIN.COM DC1$
10/06/2013 13:09:25 geb2@TESTDOMAIN.COM DC2$
10/06/2013 10:05:13 geb2@TESTDOMAIN.COM DC2$
7/06/2013 16:32:47 geb1@TESTDOMAIN.COM DC1$
I want to get the latest dates from the $data array for each computer like this:
PS> $result
Datum User Computer
----- --------- --------
10/06/2013 13:10:56 geb1@TESTDOMAIN.COM DC1$
10/06/2013 13:09:25 geb2@TESTDOMAIN.COM DC2$
I really couldn't get this result. Could you please help me on this?
$data | Foreach-Object {$_.Datum = [DateTime]$_.Datum; $_} |
Group-Object Computer |
Foreach-Object {$_.Group | Sort-Object Datum | Select-Object -Last 1}
Maybe you use the $GET_[]; statement?
这应该有效,但我现在无法测试它:
$result =$data | sort computer,{ [datetime]$_.datum } -desc | group computer | % { $_.group[0] }
