is there a way to do line-bufferd cat? For example, I want to watch a UART device, and I only want to see it’s message when there is a whole line. Can I do some thing like:
cat --line-buffered /dev/crbif0rb0c0ttyS0
Thanks.
No, but GNU grep with
--line-bufferedcan do this. Just search for something every line has, such as'^'.
