I'm calling an command line .exe from within a PoSh script.
This is generating a hit Y for Yes / N for No choice.
How can I send a Y in my PoSh script?
Thanks!

I think that is up to the program being called not PowerShell. If the program wants to accept input interactively and does not provide an input parameter for the information or a way to provide an "answer file" then I am not sure you can get around that.

Hmmmmm.

I found this on the net; the author plainly states it's a bit of a hack, but also claims to have made it work for him. I've not been able to get this to work myself.

#Pass the Y and exit

$PlinkCommand = [string]::Format('echo y | & "{0}" {1} exit',

$PlinkAndPath, $plinkoptions )

Write-Host $PlinkCommand

$msg = Invoke-Expression $PlinkCommand

Where

$PlinkAndPath is path to .exe, and

$plinkoptions are the parameters (username, password, hostname, etc)

That's not a PowerShell thing per se. What that is saying is:

echo textToPipeIn | executableName executableOptions

Which works fine in cmd Shell as well. How to pipe in more than one answer with that syntax though?

Yeah, I know it's a cmd hack, and you're right, it'll only work for a single response.

In my particular case, that's all that would have been required.

I got around it per your suggestion by using another switch.

Thanks!
