Disable PowerShell beep on backspace
This feature seems to have been added in PowerShell version 5.1, as I don't find it on my laptop still running 5.0.
When pressing Backspace in PowerShell, it will emit a 'beep' sound if there is no (more) text to delete. This is quite annoying if you accidentally hold down the key too long, as the sound will keep going for a short while after you release it.
I found this Super User question which suggests to disable the Beep service, which does work, but I would like to still be able to use beeps in scripts.
How do I disable the "beep on backspace" sound without disabling beeps completely?
The beep is provided by the PSReadline module, which shipped with Windows 10. You need to change the PSReadline option to disable the bell:
Set-PSReadlineOption -BellStyle None
If you want this change for all future PowerShell sessions, then you need to add this command to your PowerShell profile. For example, to set the option for "Current User, Current Host" ($Profile):
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
if (!(Test-Path -Path "$Profile")) {New-Item -ItemType File -Path "$Profile" -Force}
Add-Content -Value "Set-PSReadlineOption -BellStyle None" -Path "$Profile"
The first line allows your profile run a startup script when PowerShell opens (About Execution Policies). The second line tests to see if you already have a startup script defined for "Current User, Current Host". The third line adds the bell option to your startup script.
A more permanent solution that extends @PetSerAl's answer:
- Run PowerShell as administrator.
- Execute:
set-executionpolicy remotesigned. This will allow PowerShell scripts to run on your computer. If you are not sure on what that is do not continue. - Go to
C:\Windows\System32\WindowsPowerShell\v1.0if you are on Windows 10. - Create a file named
Microsoft.PowerShell_profile.ps1. - Edit that file and add
Set-PSReadlineOption -BellStyle None. - Open a new PowerShell console and you should not hear the beep any more.
All (new) PowerShell consoles for all users on your computer are now silent.
This answer is for Windows 10. For other versions of Windows, the folder might differ.
I filed this Github item against PsReadLine, as I'm not sure this change was intentional - https://github.com/lzybkr/PSReadLine/issues/422
