pwsh Out-Null not suppressing the output on Restart-Service cmdlet
Using latest version of pwsh 7.5.1 x64 machine.
Looking to suppress the output from Restart-Service cmdlet by using Out-Null, but it's not doing its thing
Get-Service DusmSvc | Restart-Service | Out-Null
WARNING: Waiting for service 'Data Usage (DusmSvc)' to start...
WARNING: Waiting for service 'Data Usage (DusmSvc)' to start...
Any ideas, anyone?
Solution
Out-Null only suppresses output sent to the success stream, and what you're seeing are Warning messages. Use the -WarningAction common parameter to suppress this output:
Get-Service DusmSvc | Restart-Service -WarningAction Ignore | Out-Null
Alternatively, you could redirect the warning stream to success, then there shouldn't be any problems:
Get-Service DusmSvc | Restart-Service 3>&1 | Out-Null
Redirecting to $null would work too, in which case you mind as well remove the need for Out-Null and redirect all output streams:
Get-Service DusmSvc | Restart-Service *>$null
