PowerShell Pipeline
Get-Service -Name 'spooler' | Stop-Service 
Get-LocalUser -name carles | Set-LocalUser -Description 'Admin of the Computer'
Get-Service | Out-File -FilePath c:\PowerShellTest\Services.txt

Format Data
Get-Service | Format-List -Property name
Get-Service | Format-List -Property name, status | Out-File -FilePath c:\PSTest\FormattedList.txt

Properties are attributes
Methods are like actions (Start, stop, turnonlights,etc)
Blueprints are like classes, and from classes, objects are made.
A car has a method: Start()
2 Objects are different because the value of their properties and implementation of their methods, but both are still objects.

Properties and methods of an object
Get-Service | Get-Member
Get-LocalUser | Get-Member

How to get results we need on a property of an object?
Get-Service | Where-Object {$_.status -eq 'running'} | Out-File -FilePath 'C:\PSTest\report.txt'
This command gets all the services with status Running and put them into a file.
Get-LocalUser | Where-Object {$_.enabled -eq 'True'} | Set-LocalUser -Description 'Admin'
This Command will change the description of all the enabled users to Admin.

How do we select specific information?
Get-Service | Select-Object -First 5
Get-Service | Select-Object -Last 5
Get-Service | Select-Object -Property name, status -First 5 |Out-File -FilePath 'C:\PSTest\Services.txt

Sort in alphabetical order
Get-Service | Sort-Object -Property 'Status'
Get-EventLog -LogName system -newest 5 | Sort-Object instanceid
Get-Service | Where-Object {$_.status -eq 'stopped'} | Sort-Object -Property displayname | Select-Object -First 5 | Format-List
