Sometimes when I code Powershell I find small trinkets I wish too remember, so I’m gonna save them here.

This is a well, small PS variable list for me, with links to articles about them.

Variable	Description
$PSVersionTable.PSVersion	Powershell version,if it is missing, then PS = 1.0
$PSCmdlet.ParameterSetName	If using parameterSets with function, this will have which set was used.
$MyInvocation.MyCommand.Name	Returns the current functions name.
$PSBoundParameters['Verbose']	Will be true if function is called with -Verbose
$PSBoundParameters['Debug']	Will be true if function is called with -Debug

Useful functions from .NET

Function	Description
[io.path]::GetTempFileName()	Returns a temporaryfile name in the tempdirectory of the current user
