It's not line-buffered. It's optimally buffered, i.e. the buffer is flushed whenever it's full (obviously) or whenever the loop goes back to reading with a chance of blocking. When you test with a loop around echo, you send lines one by one, so the behaviour appears to be line buffering, but that's only an artifact of your test. -- Laurent
