but got error

- was unexpected at this time.

On command line, powershell command work fine. Trying to escape some dashes and semicolon, but have no luck. What could cause this error?

Remember you are using a batch file. So any special characters need to be escaped. The closing parentheses thinks you are closing the FOR argument so it thinks the hyphen is a command. You need to escape them.

Code: Select all

for /f "usebackq tokens=1-3 delims=- " %%a in (`
powershell.exe -Command "Get-EventLog -ErrorAction SilentlyContinue -Newest 1 -LogName System -EntryType Error -Source Tcpip | ForEach-Object { \"$(Get-Date $_.TimeGenerated^) - $($_.ReplacementStrings -join '#'^)\" }; Write-output ^$error[0]"
`) do (
echo %%a %%b %%c
)
