PowerShell: how to grep command output?

In PowerShell I have tried:

alias | select-string Alias

This fails even though Alias is clearly in the output. I know this is because select-string is operating on some object and not the actual output string.

What can be done about it?

Try this:

PS C:\> ipconfig /displaydns | Select-String -Pattern 'www.yahoo.com' -Context 0,7

>     www.yahoo.com
      ----------------------------------------
>     Record Name . . . . . : www.yahoo.com
      Record Type . . . . . : 5
      Time To Live  . . . . : 27
      Data Length . . . . . : 8

PS> alias | Where-Object {$_.Definition -match 'alias'}

CommandType     Name                   Definition
-----------     ----                   ----------
Alias           epal                   Export-Alias
Alias           gal                    Get-Alias
Alias           ipal                   Import-Alias
Alias           nal                    New-Alias
Alias           sal                    Set-Alias

what would be contradict of match in PS then as in to get field not matching a certain value in a column
