With a single function command-line tool ‘cmdlet’ (command-let), automation becomes much easier. The combination of cmdlets is mainly used to perform complex tasks. The cmdlet is written in a verb-noun form such as ‘Get-Help’, ‘Get-Command’, ‘Get-Process’ etc. Any professional can use cmdlets efficiently for automating purposes. There are more than a hundred basic core cmdlets. Apart from that, you can create your own cmdlet using scripts and share it with other users.
Microsoft states that Powershell is built on top of the .NET Common Language Runtime (CLR), and accepts and returns .NET objects. This means that instead of plain text as output, Powershell delivers data in a directly usable format. The combination of these objects can solve all the complex calculations in a simple way. You can further use the object directly or modify it. Hence, it makes it much easier for system administrators to execute their tasks.
