Given that the buffer change flag is already set, it is not easy for ed to tell whether an intervening command would have set the buffer change flag. For example, 'a\n.\n' would not set the buffer change flag, but should make e or q repeat the warning. Therefore I propose a wording like the following: "If another e or q command is then attempted with no intervening command that can set the buffer change flag, it shall take effect."

[Issue 8 drafts 0001786]: ed behavior on non-existing filename
The following issue has been SUBMITTED. == https://austingroupbugs.net/view.php?id=1786 == Reported By:eblake Assigned To: == Project:Issue 8 drafts Issue ID: 1786 Category: Shell and Utilities Type: Clarification Requested Severity: Objection Priority: normal Status: New Name: Eric Blake Organization: Red Hat User Reference: ebb.ed Section:XCU ed Page Number:2801 Line Number:92899 Final Accepted Text: == Date Submitted: 2023-11-02 15:13 UTC Last Modified: 2023-11-02 15:13 UTC == Summary:ed behavior on non-existing filename Description: This bug was created as fallout from investigating https://austingroupbugs.net/view.php?id=251, investigating whether ed can create pathnames containing a newline. It turns out that the standard is silent on what happens when the e, f or w commands are used with a filename (whether explicit or implicit) that does not yet exist. Existing implementations differ on whether e can create a file: GNU ed: $ rm -f hi $ echo q | ed hi hi: No such file or directory $ echo $? 0 $ echo f | ed hi hi: No such file or directory hi $ echo $? 0 $ ls hi ls: cannot access 'hi': No such file or directory $ echo w | ed hi hi: No such file or directory 0 $ ls hi hi whereas on FreeBSD 13: # rm -f hi # echo q | ed hi hi: No such file or directory # echo $? 2 # echo f | ed hi hi: No such file or directory # echo $? 2 # echo w | ed hi hi: No such file or directory # ls hi ls: hi: No such file or directory However, all implementations I tested appear to allow f and w allow a filename argument that does not yet exist, at which point w creates that file (which matches the requirement for w at line 93110): $ rm -f hi $ printf 'f hi\nw\n' | ed hi 0 $ ls hi hi Back in the context of https://austingroupbugs.net/view.php?id=251, where we stated that the file command line argument to ed is treated the same as an explicit argument to the e command, other than the possibility of including a newline in the name, whether or not you can use ed to create a filename with a newline then depends on the behavior of whether a non-existing pathname is permitted with the e command. However, the proposed wording here is intended to apply as-is regardless of whether we also include the changes in https://austingroupbugs.net/view.php?id=251. Desired Action: In XCU ed EXTENDED DESCRIPTION, page 2801 line 92901, in the Edit Command text, after the sentence:If no pathname is given, the currently remembered pathname, if any, shall be used (see the f command).insert another sentenceIf the pathname names a file that does not exist, it is unspecified whether this is treated as an error, or whether a warning is emitted in place of a byte count and the resulting buffer is left empty.
