In this blog post, we will discuss cmdlet in PowerShell and how to get started with PowerShell cmdlet. Cmdlet is a set of built-in PowerShell commands that can be used to interact with other cmdlets or used as a tool for automation. The basic difference between a cmdlet and a normal command is that cmdlet returns objects instead of plain text when executed. PowerShell comes with a set of pre-installed cmdlet provided by PowerShell. You can add additional PowerShell provided cmdlet or create your own custom cmdlet.
You can list all available cmdlet using Get-Command cmdlet. Each cmdlet has a predefined set of parameters that can be used with the cmdlet to control its behavior. You can get the list of parameters using Get-Help cmdlet. There are also some common parameters that can be passed to every cmdlet. Each cmdlet returns some objects as output. You can get a list of all objects using Get-Member cmdlet.
