Useful powershell “variables”

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

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