PowerShell commands are created of a verb, followed by a hyphen (or minus sign), followed by a noun. The get-command cmdlet demonstrates the structure. The verb “get” is followed by a hyphen, which is followed by a noun “command.” PowerShell uses the singular form of the noun, even when you want to find multiple items that convince your requirements. Thus, you might use get-process to get all the processes running on a system, as opposed to get-processes.

You can use wildcards to focus your search for the relevant command. For example, to find all commands that use the get verb, use the following command:

get-command get-*

There are different ways you can get help on cmdlets while using powershell, You use the get-help cmdlet to get help information about individual cmdlets. For example, to get help on the get-process cmdlet type either:

get-help get-process

or

get-process -?

The help for each command or other piece of syntax is structured in the following sections by powershell:

• Name – The name of the cmdlet.
• Synopsis – A brief text description of the cmdlet.
• Examples – Examples of how to use the cmdlet.
