I have a script that can be run either locally or remotely (via WinRM), however I would like it to behave slightly differently when run on a remote machine. I realise that I can pass in a switch to the script to identify whether it is running locally or remotely, but I want to know if it is possible for the script itself to detect whether it is running remotely?
Get-Host
returns, amongst other information a Name
:
PS> (Get-Host).Name ConsoleHost PS> (Invoke-Command -ComputerName dev2 -Script {Get-Host}).Name ServerRemoteHost
if ($PSSenderInfo) {
"Running remote"
}
else {
"Running local"
}
Checking whether $profile
is defined works for me. I don't know how reliable this is, but various sources suggest that no profile is loaded in the remote session. I couldn't check the computername, as I don't have any way of knowing in advance which machine is local and which is remote.
$RunningLocally = $profile -ne $null
you can check computername in $MyInvocation :
PS>Invoke-Command -ComputerName smacnt01 -ScriptBlock {$MyInvocation}
PSComputerName : smacnt01
RunspaceId : 333f5333-0ca5-4461-8f38-cb086fbd1ea4
MyCommand : $MyInvocation
BoundParameters : {}
UnboundArguments : {}
ScriptLineNumber : 0
OffsetInLine : 0
HistoryId : -1
ScriptName :
Line :
PositionMessage :
InvocationName :
PipelineLength : 1
PipelinePosition : 1
ExpectingInput : False
CommandOrigin : Runspace
I think it's possible in your script test if
$myinvocation.mycommand.path -eq $null
then if is true
is running remotely via Invoke-command.
I have not test it accurately but I think it can work.
