New-TemporaryFile cmdlet in PowerShell is used to create a temporary file easily. Creating a temp file in PowerShell is a common task when you want to store the data temporarily during the script execution.
In this article, we will discuss how to create a temp file in PowerShell using the New-TemporaryFile cmdlet.
Access the Temp Folder in PowerShell
In Windows, the operating system and application store the data temporarily in a temp folder. The system’s team folder path can be accessed using the environment variable $env:temp
The above PowerShell script gets the path of the current user’s temp folder as given below:
Now, let’s create a temporary file in the system temp folder.
PowerShell Create Temporary File using the New-TemporaryFile
PowerShell has a built-in cmdlet New-TemporaryFile that creates a temporary file with extension .tmp and stores it in the system’s temp folder.
$tempFile = New-TemporaryFile $tempFile
In the above PowerShell script, the New-TemporaryFile cmdlet creates a temp file
`tmp913E.tmp` and stores it in the temp folder location.
The output of the above script generates a unique file with an extension .tmp and displays file details as given below:
Create a Temporary File with a Custom Name and Extension
When working with data that needs to be stored temporarily during script execution, we need to create a temporary file with a custom name and extension. In PowerShell, it can be easily done using the following script:
# Access the temp folder path $tempFolder = $env:Temp # Define Custom Name for file $customFileName = "rabbitmq_log" # Define custom extension for file $extention = ".txt" # Join the file name with extension $customTempFileName = $customFileName + $extention # Join the system temp folder path with custom file name $customTempFilePath = Join-Path -Path $tempFolder -ChildPath $customTempFileName # Create a temp file at system temp folder $tempFile = [System.IO.FileInfo]::new($customTempFilePath) $tempFile.Create().Close() # Print the temporary file location Write-Host "Temporary file created at: $($tempFile.FullName)"
The above PowerShell script creates a temporary file with a custom name and extension
`rabbitmq_log.txt` in the system’s temp folder and print the file location as given below:
Temporary file created at: C:\Users\shellladmin\AppData\Local\Temp\rabbitmq_log.txt
Delete Windows Temporary Files
It’s important to clean up temporary files after they are no longer needed.
Use the Remove-Item cmdlet in PowerShell to remove a temporary file.
$tempFile = "C:\Users\shelladmin\AppData\Local\Temp\rabbitmq_log.txt" Remove-Item -Path $tempFile.FullName -Force
The above PowerShell script uses the Remove-Item cmdlet to remove the temporary file from the system temp folder specified by the Path parameter $tempFile. This command uses the Force parameter to forcefully delete the file if it is in use.
I hope the above article on how to create a temporary file in PowerShell using the New-TemporaryFile cmdlet is helpful to you.
