Powershell keeps file open Out-file -append / Add-content
Hi AkitoTheGambler,
you can address this file locking issue by using the .NET System.IO.File methods for writing to the file. Replace all occurrences of Out-File -FilePath $logFile -Append with [System.IO.File]::AppendAllText($logFile, $yourMessage).
For instance, instead of:
Write-Output $certMessage | Out-File -FilePath $logFile -Append
You can try:
[System.IO.File]::AppendAllText($logFile, $certMessage)

unfortunately we are using ConstrainedLanguage mode so we cannot use it
but running out-file manually doesnt usually lock the file after running
but somehow in some cases in scriptblocks or functions it does.
i dont understand why tho. (but not always, idk what the conditions are that cause it to behave like this)

i was trying to figure out why this happens as it only breaks inside the Scriptblock but doesnt hangup and keep it open if its everything outside the scriptblock
so
Write-Output $certMessage | Out-File -FilePath $logFile -Append Write-Output $timestampMessage | Out-File -FilePath $logFile -Append
always works finebut everything inside the foreach scriptblock fails
- Hi AkitoTheGambler,
Did you find a solution for this? I have the same issue. I use a function to write data to a log file and I get "random" access denied errors when writing to the file.
