Just found this…you may already know about it, but if not, hopefully it helps you with Sitecore development.
Sometimes you want to tail the log files from Sitecore, and see what’s happening in real-time on your Sitecore site.
But then you do a build or make a config change, logging stops in that file and a new log file is created. You then need to open that new file in the tailing program.
Anyway, I just found you can easily change Sitecore to always log to the one file.
