How do I automatically answer “yes” to a prompt in Powershell?

Question

How can I input \"yes\" as an answer to an interactive question in a PowerShell session? I know, in Bash, Yes is the tool to answer \"yes\" on the prompt. In my

Answer 1

I was trying to kill a pesky startup program and found that the Stop-Process and / or the program would not accept a piped input (no Echo Y | for me!) but I changed JPs answer a little bit: Stop-Process -name [program.name] -Force ; ran as administrator and it worked like a charm.

Answer 2

I was also having the same issue. The solutions tried by me included:

• ECHO 'Y' |
• Command-Name -Force
• $ConfirmPreference = 'None'

However, none of them seemed to do the trick.

What finally solved the problem was:

Powershell-Cmdlet -Confirm:$false

It suppresses all confirmation prompts for the duration of the command and the command would be processed without any confirmation.

Answer 3

Inspired by other answers, here is my example:

ECHO Y | powershell Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All

Answer 4

You can test these old fashion ways :

Cmd /c "GpUpdate.exe /FORCE <C:\temp\response.txt"

ECHO 'Y' | GpUpdate.exe /FORCE

Get-Content "C:\temp\response.txt" | GpUpdate.exe /FORCE

Answer 5

Using ECHO worked for me. I am running RSKeyMgmt.exe in my Powershell script and it prompted Yes(Y)/ No(N). So when I do

ECHO Y | RSKeyMgmt.exe...

It did not prompt the question and the command was executed correctly.

So I think ECHO 'someoption' should work for other cases too.
