The PowerShell ecosystem is more diverse than it used to be which makes determining the PowerShell host a bit more difficult.
The variable $host, and its Name property, is a good starting point.
PS> $host.Name
ConsoleHost
You get ConSoleHost if you’re running in the console.
For ISE you get – Windows PowerShell ISE Host
And for VScode you get – Visual Studio Code Host
If you want to know the PowerShell version as well it’s a bit more awkward.
$host.Version works for the console and ISE as it returns the PowerShell version. In VScode however it returns the version of VScode. The best route is to use
$PSVersionTable.PSVersion
While you’re at it you may want to check the edition of PowerShell – Core or Desktop
PS> $PSVersionTable.PSEdition
Core
To make that a bit easier
function get-powershellhost {
New-Object -TypeName PSobject -Property @{
Hostname = $host.Name
PSversion = $PSVersionTable.PSVersion
PSEdition = $PSVersionTable.PSEdition
}
}
The function runs in the console, ISE and VScode and was tested across Windows PowerShell v5.1 and PowerShell v6.1
