Are you saying it's buffering what you see in your terminal, or what's
written to the file, or both?

I can't recall really seeing it buffer like that but maybe I'm just not
paying close enough attention. It's always seemed pretty real time to me.

Can you post an example of a command line where you'd see this happening?

Generally for things like moinitoring log output in real time, I'll use
tail -f and pipe that through other commands like grep if I need to.

I'll use tee for something like running a script, where I want to see
stdout but also have it captured to a file I can refer to later.
