In this blog post, we will discuss Select-Object cmdlet in PowerShell. You can use Select-Object cmdlet to select specific properties of object in the output. You can further limit the number of results in the output using ‘First’, ‘Last’, Unique’, ‘Skip’, and ‘Index’ parameters. Select-Object also supports optimization where is it stops processing once its reach selection criterion.
