in thread (SOLVED) How do I display only matches

To hopefully add a bit more clarity (or at least improve my own understanding), POSIX has a binary model of files and "\n" is always <LF> in user programs. But sometimes the kernel can translate <LF> to <CR><LF> and this usually means that a terminal driver is involved somewhere — this is frequently seen when using Expect, which uses the pty facilities, which emulate a terminal and therefore involve the kernel terminal driver.

As far as I know, sockets are always binary and no such translation ever occurs, so I am unsure where this misinformation about network line endings originated. Perhaps STREAMS had such a translation module?

    I don't know enough about the details of the kernel's behavior to say for sure, but what you write sounds correct to me. I have my guesses about where the misinformation originated, but of course I can't say what another person is thinking.
