I know there's a way because I've done it before in log files and sent the output here for debuging
If a file keeps getting additions to it (append?) how do you read the additiosn to the file? Like say you have program > file to log what it does but you also want to see what it's doing.
Another question: When you use > or >> it sends everything but errors / warnings. How do you send even the errors to the file?
What I'm wanting to do is log my bzfs server but I also want to see normal output from it. bzfs ..... > logfile. grep | cat-nsf logfile...
