Cmdlet vs. Command:

Cmdlets are different from commands in other command-shell environments in the following manners −

Cmdlets are .NET Framework class objects It can’t be executed separately

Cmdlets can construct from as few as a dozen lines of code

Parsing, output formatting, and error presentation are not handled by cmdlets

Cmdlets process works on objects. So text stream and objects can’t be passed as output for pipelining

Cmdlets are record-based as so it processes a single object at a time

Most of the functionality comes from Cmdlet’s which is always in verb-noun format and not plural. Moreover, Cmdlet’s return objects not text. A cmdlet is a series of commands, which is more than one line, stored in a text file with a .ps1 extension.

A cmdlet always consists of a verb and a noun, separated with a hyphen. Some of the verbs use for you to learn PowerShell is:

Get — To get something

Start — To run something

Out — To output something

Stop — To stop something that is running

Set — To define something

New — To create something
