What is Cmdlet?

The cmdlet (pronounced "command-let") is a lightweight Windows PowerShell script that performs a function.

A command, in this context, is the specific order from the user to the computer operating system or an application to perform a service, such as displaying all files or running programs.

Although Windows PowerShell includes over 200 basic short cmdlets, admins can also write their own cmdlets and share them.

Cmdlet has the extension .ps1 . Each cmdlet has a help file, which can be accessed by typing:

Get-Help -Detailed

Cmdlet is different from the usual commands?

Cmdlet differs from commands in other command-shell environment as follows:

• Cmdlets are examples of. NET Framework classes and are not standalone executables.
• Cmdlet can be made from several dozen lines of code.
• Cmdlets usually do not themselves parse, present errors or format the output. The parsing, error presentation and output format are handled by Windows PowerShell Runtime.
• Cmdlets handle input objects from the pipeline (data flow moving through cmdlets) instead of from text streams, and cmdlets usually distribute objects as outputs to the pipeline.
• Cmdlet handles one object at a time.
