PowerShell comes with a powerful yet simple way of monitoring file changes. Let’s assume you have a log file that changes every now and then. This would be a PowerShell script that monitors the log file for changes, and whenever a change occurs, executes some code:
# make sure this points to a log file $Path = '\\myserver\report2.txt' Get-Content -Path $Path -Tail 0 -Wait | ForEach-Object { "Detected $_" }
Just make sure you adjust $path to point to some real log file. Whenever you append text to the file (and save the change), the ForEach-Object loop executes the script block and outputs “Detected ”. This way, you can easily respond to the actual change.
Get-Content does the heavy lifting: -Wait enables the content monitoring, and -Tail 0 makes sure you ignore existing content and look only for newly added text.
