EXAMPLES:

Get-Service | Where-Object {$PSItem.status –eq ‘running’} | Out-File –FilePath  ‘C:\reports\report.txt’

How can we get only the stuff we need based on a property of an object ?

EXAMPLES:

Get-LocalUser | Where-Object {$PSItem.enabled –eq $false} | Set-LocalUser `  –Description ‘Disabled Account’

• How do we select specific information ?

  
  

• EXAMPLES:

• Get-Service | Select-Object –First 5

• Get-Service | Select-Object –Last 5
