cmdlet<\/h2>\n\n\n\n

cmdlet (“command-let”) is a specialized .Net class that implements a specific task or operation and will have required and optional parameters.
Naming convention used to construct a cmdlet follows a verb-noun object name. Verbs are action oriented words, such as Add, Get, Set, Update; Nouns describe what will be acted on such as Get-Azure(Azure Cloud Service), New-ADUser (Active Directory User), Get-SPUser (Sharepoint User). The Nouns may represent core module objects and verbs may invoke methods\/commands that were developed to be run as cmdlets. Example Microsoft.Sharepoint.PowerShell.dll includes over 800 commands.
<\/p>\n\n\n\n

Important cmdlets:<\/h2>\n\n\n\n

get-Command<\/strong> this will display all the cmdlets that are available in the current PowerShell Session. This can be filter using get-Command -noun [name] ([name] can use *wilcard* for searching and matching nouns)

get-Help<\/strong> displays help information for any cmdlet and can be set for 3 levels of details: Normal, Detailed, and Full

get-Member<\/strong> displays a list of all the methods and properties that are associated with any cmdlets using piplines

where-Object<\/strong> creates a filtered list of the objects where objects matches the criteria parameter<\/p>\n\n\n\n

pipeline<\/h2>\n\n\n\n

The concept of passing of a result of a command to another command.

Example get-Service | where-Object {$_.DisplayName -like “Sharep*”}
Returns objects where DisplayName starts with Sharep<\/p>\n\n\n\n

parameter set<\/h2>\n\n\n\n

parameter sets are different ways to run a certain command which are mutually exclusive and can’t be combined. Listed in the get-Help result Syntax. This will list parameters can be run at the same time and list separate grouping called syntax for mutually exclusive parameter sets. <\/p>\n\n\n\n

\"ShowNewFolderButton<\/figure>\n\n\n\n
OpenFileDialog<\/h3>\n\n\n\n
$FileBrowser = New-Object \nSystem.Windows.Forms.OpenFileDialog<\/code>\n-Property @{ \n  Title = \"Select Windows Server image\"\n  InitialDirectory = [Environment]::GetFolderPath('MyComputer') \n  MultiSelect = 'false'\n  }<\/pre>\n\n\n\n
