Posix says the N command does NOT trigger the default print at EOF: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/sed.html
[2addr]N Append the next line of input, less its terminating <newline>, to the pattern space, using an embedded <newline> to separate the appended material from the original material. Note that the current line number changes. If no next line of input is available, the N command verb shall branch to the end of the script and quit without starting a new cycle or copying the pattern space to standard output. Except that's not what the gnu/dammit version does: $ echo one | sed N one $ echo -e 'one\none\none' | sed 'N;ax' one one x one Why? (It looks like N acts as "b" at eof, which will do the default print as normal at end of pattern, but that's not what posix SAID to do...? I implemented what posix sed. At the time, I thought that was what the gnu/dammit one was doing too, but apparently not in devuan baywatch?)
