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 situation, I can't suppress the prompt.

The script I'm running stops at

Please reply "yes" if you want to continue:

How powershell can run the script and "answer" yes when pompted?

Need more context, for instance what is cfgsave ? Is it something you wrote or are you just trying to use Powershell to run it. How would cfgsave work without Powershell, it sounds like it would display a window with a 'yes' button? — Oliver Gray, Dec 28 '12 at 14:39

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.

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.

Inspired by other answers, here is my example:

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

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

I am just using powershell to run it. CFGsave is an external command run on a switch. I would like to run this command from powershell without having to respond to yes or no. Also thanks JP but i would prefer powershell workaround if it exists. :) for my learning more than anything else. – Frown Mar 19 '13 at 14:23

I had the same issue trying to use:

net use * /delete

It always prompeted me for a Y/N and tried the solutions in here but none worked, so I'm reporting what worked for me:

net use * /delete /y

Maybe every command has a silent confirmation.

This worked for me when installing something from an "untrusted source":

ECHO Y | powershell Install-Module -Name PSWindowsUpdate | ECHO Y

I was trying to programmatically install the Windows Update powershell tool set :)

For Azure CLI commands --yes is often an option.

Disable-NetAdapter -name "Wi-Fi" -Confirm:$false

This worked for me in this scenario with PowerShell.

I had a similar problem but it wasn't just a yes/no option. I had some scripts that prompted for a choice of multiple options and I wanted to include them in some automated scripts. The prompts were something like this:

Select Option
What option do you want to use:
[A] Option A  [B] Option B  [C] Option C  [?] Help (default is "A"):

I found that this worked:

Echo A | powershell.exe ./script.ps1

Echo is simply an alias for 'Write-Output'. If there were more than one prompt, I could simply separate the inputs with a space like:

Echo A F G

I don't know why I needed to include the powershell.exe instead of just passing in the echo into the script.

Instead of putting the echo command in the front, (which will just echo all following inputs, or throw an error about the pipe) I put it at the end and that worked.

Install-Module -Name DisplaySettings | ECHO Y

Does this depend on the command/function being ran? – ryanwebjackson Jun 07 '23 at 11:59

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.

The following Powershell worked for me:

Write-Output 'Y' | .\plink.exe <ip_address> -l <username> -pw <password>

This will output the 'Y' character to the next pipeline object.
