| Sep 7 at 17:59 | comment | added | Toby Speight | Interestingly, GNU ed emits the message to standard ouptut stream, not the error stream. But does exit with status 1. So it seems it's not quite sure whether it's an error or not. | |
| Jun 5, 2021 at 4:12 | comment | added | Anders Kaseorg | @Makonede The 0\n only appears when providing a 0-byte input file as an argument to ed. The TIO wrapper does this, but one doesn’t need to do so in general. If one does, the 0\n is not part of an error message: it appears before any code is read, and indicates the size of the input file. | |
| Jun 4, 2021 at 20:26 | comment | added | Makonede | This outputs 0\n?\n to STDERR, which is longer than the source code. This can be fixed at no cost, however, by using -s. | |

| Jul 4, 2018 at 14:12 | comment | added | Dennis | As pointed out in a flag, the error is fatal if the code isn't read from a terminal. Try it online! | |

| Feb 20, 2018 at 8:31 | comment | added | Martin Ender | If the error isn't fatal as Mark points out, I'm afraid this answer is invalid. Please edit the answer if there's an ed implementation where the error actually terminates the program, and flag it for moderator attention so that it can be undeleted. | |

| Jul 26, 2017 at 10:52 | comment | added | Toby Speight | This answer was exactly my first thought on reading the question. Ed is justly famed for its succinct error messages. | |

| Jul 21, 2017 at 22:34 | comment | added | Stephen | Can ed do addition and primality testing? Or is that not required for this type of challenge? | |
| Jul 21, 2017 at 20:24 | comment | added | Adalynn | Not entirely, if for some reason the newline alone counts as an error, or if there exists an error that is one character long and does not have a trailing new line, then it's possible. | |
