First steps with PowerShell

The five commands to know to explore and filter your system.

1. Find a command and read its help:

   Get-Command *process*
   Get-Help Get-Process -Examples

   Copy
2. List files:

   Get-ChildItem C:\Users -Recurse -Filter *.pdf

   Copy
3. Chain with the pipeline: filter, sort, pick columns:

   Get-Process | Where-Object CPU -gt 100 | Sort-Object CPU -Descending | Select-Object Name, CPU -First 5

   Copy
4. Export a result to a file:

   Get-Service | Where-Object Status -eq Running | Export-Csv services.csv -NoTypeInformation

   Copy
5. PowerShell handles objects, not text: each column is a property you can filter.
