So let's re-open this for now, especially if you're going to raise this issue further on the Austin group. When you do, please send a note with the URL so we can keep track as well. The behavior already differs between implementations, so it'll be intersting to see what's decided. I assume that a discussion about this will cover all commands, e.g. this as well: $ echo xyz | sed -e 'y/xyz/1\n3/' 1 3 versus: $ echo xyz | sed -e 'y/xyz/1\' -e '3/' sed: -e expression #1, char 8: unterminated `y' command thanks, - assaf

In the description of the s command POSIX says: A line can be split by substituting a <newline> into it. The application shall escape the <newline> in the replacement by preceding it by a <backslash>. So the examples without the backslash are irrelevant as are the examples with the y command. As for concatenation, POSIX says: -e script Add the editing commands specified by the script option-argument to the end of the script of editing commands. And more importantly: If any -e or -f options are specified, the script of editing commands shall initially be empty. The commands specified by each -e or -f option shall be added to the script in the order specified. When each addition is made, if the previous addition (if any) was from a -e option, a <newline> shall be inserted before the new addition. The resulting script shall have the same properties as the script operand, described in the OPERANDS section. This is a case where the previous addition was from a -e option, so a newline should be inserted. After the newline is inserted the script we have is s/foo/bar\ baz/ And that "resulting script shall have the same properties..." means that it should work the same as if it were in a file or in a single argument with a literal newline. > I'm marking this as 'done', but discussion can continue by replying to > this thread.

I do not have a patch, but if you are interested I can ask on the Austin group list and see if there is any consensus and if so whether they would change the wording of the standard.

(for past discussion, see https://bugs.gnu.org/19842 ). First, for completeness, this is the behavior with various sed implementations: $ echo foo | sed-gnu-4.3 -e 's/foo/bar\' -e 'baz/' sed: -e expression #1, char 10: unterminated `s' command $ echo foo | sed-netbsd-7.0 -e 's/foo/bar\' -e 'baz/' bar baz $ echo foo | sed-freebsd-10 -e 's/foo/bar\' -e 'baz/' bar baz $ echo foo | sed-openbsd-5.9 -e 's/foo/bar\' -e 'baz/' barbaz $ echo foo | sed-heirloom -e 's/foo/bar\' -e 'baz/' Undefined label: az/ $ echo foo | sed-busybox -e 's/foo/bar\' -e 'baz/' bar baz Second, Notice the backslash plays a role, indicating continuation for some implementations. Without backslash, '-e' are not always concatenated: $ echo foo | sed-netbsd-7.0 -e 's/foo/bar' -e 'baz/' sed-netbsd-7.0: 1: "s/foo/bar ": unescaped newline inside substitute pattern $ echo foo | sed-freebsd-10 -e 's/foo/bar' -e 'baz/' sed-freebsd-10: 1: "s/foo/bar ": unescaped newline inside substitute pattern $ echo foo | sed-openbsd-5.9 -e 's/foo/bar' -e 'baz/' barbaz $ echo foo | sed-busybox -e 's/foo/bar' -e 'baz/' sed: unmatched '/' Third, even in OpenBSD's sed which accepts this construct, it seems this is limited to 's'. It doesn't "just work" in all commands: $ echo a | sed-openbsd-5.9 -e 'y/abc/123/' 1 $ echo a | sed-openbsd-5.9 -e 'y/abc/1\' -e '23/' sed: 1: "y/abc/1\": unterminated transform target string $ echo a | sed-openbsd-5.9 -e 'y/abc/1' -e '23/' sed: 1: "y/abc/1": unterminated transform target string as opposed to Busybox where it does work: $ echo a | sed-busybox -e 'y/abc\' -e '/123/' 1 Lastly, GNU sed does have one special case where trailing backslash plays a role: in a/c/i commands. This is specifically done to facilitate programs such as: $ echo a | sed-gnu-4.3 -e '1i\' -e 'foobar' foobar a $ echo a | sed-openbsd-5.9 -e '1i\' -e 'foobar' foobara $ echo a | sed-netbsd-7.0 -e '1i\' -e 'foobar' sed-netbsd-7.0: 1: "foobar ": invalid command code f As such, I would say that this is not bug per-se in gnu sed. It is not clear what is the correct behavior, and depending on one's POSIX interpretation might even be undefined. I'm marking this as 'done', but discussion can continue by replying to this thread. Better yet - if you have a patch that adds this functionality without causing regressions, we can look into incorporating it. regards, - assaf

I think the solution to this mystery might be that the above statement is a good deal more strict than people have taken it. It speaks of "commands specified by each -e". Well, the example case's -e options _do_not_ each specify commands. They each only specify part of one command. So as I read this, this report is invalid by way of its expectations not being backed by the POSIX specification.

It says nothing about analyzing, compiling, building the internal structures, it only talks about adding to "the script of editing commands" which will then be run. "The script of editing commands" refers to a representation of the editing commands in accord with the descriptions that follow on the page, i.e. text commands, a sed script. This is supported by the following line: When each addition is made, if the previous addition (if any) was from a -e option, a <newline> shall be inserted before the new addition. The newline is mentioned because it is referring to the text representation of the script (the only representation mentioned on the page). It explains that all the parts from -e and -f should in effect be concatenated to a single sed script, with newlines after the -e option arguments. e.g.: sed -e 's/foo/bar\' -e 'baz/' and printf %s\\n 's/foo/bar\' 'baz/' > script sed -f script should be identical, due to that newline. Thanks, Evan

However, it is not written in anywhere that multiple -e and/or -f options must be analyzed after the concatenation. It may be concatenated after each -e and/or -f options are parsed. By the way, /usr/bin/sed and /usr/xpg4/bin/sed on Solaris 11, /usr/bin/sed on HP-UX 11.23 also behave as same as GNU sed.

I respectfully disagree with your interpretation. The -e and -f options talk about "the script of editing commands" as the entire script/program that will run once sed starts reading input. Both -e and -f add commands to "the end of the script of editing commands." The line you quoted uses the exact same phrase: 1) -e script Add the editing commands specified by the script option-argument to the end of the script of editing commands. 2) -f script_file Add the editing commands in the file script_file to the end of the script of editing commands. 3) If any -e or -f options are specified, the script of editing commands shall initially be empty. I posit that "the script of editing commands" means the same thing in all three places. Therefore (3) means that the script/program that sed will run is empty before the first -e or -f. Your interpretation would cause "the script of editing commands" to mean something different in (3) than it means in (1) and (2). Thank you, Evan

But using multiple -e instead of a literal newline fails: $ sed -e 's/foo/bar\' -e baz/ sed: -e expression #1, char 10: unterminated `s' command The following is from POSIX[0]: If any -e or -f options are specified, the script of editing commands shall initially be empty. The commands specified by each -e or -f option shall be added to the script in the order specified. When each addition is made, if the previous addition (if any) was from a -e option, a <newline> shall be inserted before the new addition. The resulting script shall have the same properties as the script operand, described in the OPERANDS section. My reading of that leads me to believe that the two commands should create identical scripts, but GNU sed seems to me interpreting the script before the addition of the newline and second -e's argument. Is this a bug or desired behavior? Thanks, Evan $ sed --version sed (GNU sed) 4.2.2 Copyright (C) 2012 Free Software Foundation, Inc.
