Notes: Cmdlets and Members
Native powershell coammnds, not stand alone executables. Cmdlets perform an action and typically return a Microsoft .NET object
Powershell uses a Verb-Noun name pair to name cmdlets
The verb identifies the action that the cmdlet performs, and the noun identifies the resource on which the cmdlet performs its action
- Get-Help
- Get-Process
- Get-Service
Members of the class that contain data, Different types of objects have different properties
ScriptProperty - A property defined by script langiage whose value is the output of a script
AliasProperty - Defines a new name for an existing property
NoteProperty - Defines a property that has a static value
Get-Process displays only 7 properties. To see the properties you want, you can use "select"
- You can Select all ("Select *")
Get-Process | select Name, StartTime
A set of instructions that specify an action you can perform on the object returned by the cmdlet
Kill method for a Process Object returned by Get Process cmdlet, terminates the process
$notepad = Get-Process notepad
$notepad.Kill()
Powershell includes the $PSItem variable and its alias, $_, as automatic variables in script blocks that process the current object, such as in the pipeline
The $_ automatic variable represents each object that's passed to the Where-Object cmdlet. The first command uses the script block format, the second command uses the comparison statement format
Powershell has commands for controlling the flow of execution within your scripts. One of those statements is the switch statement
help *service* will give you a list of items on "help" that contains the word service
