Powewrshell Parse file help

Hey,

So I will explain the overall situation first for better understanding. I have a script running that mirrors two directories and updates a log file about what happens between the two directories. I want to Parse this log file to get updates as they come in (while the script is running) and I want these to send me an email of what has changed, like a notification almost.

I'm unsure on how I would go about doing this after reading through some of the command lists online.

not all that strong with PowerShell so any help would be greatly appreciated, Thanks in advance :)

Edit: I don't want to get notified about the same bit of info more than once if possible.
