The standard is most likely also read by people that are not experts, just like I am, and who don't know or remember that two leading / in a pathname are actually special as per 3.271 Pathname. Given that many people think that *any* sequence of / folds in a pathname... I'd probably even give the '/./dev/stdout' example. What about: "... for example, -o /./dev/stdout or -o ///dev/stdout but not -o //dev/stdout (see 3.271 Pathname)." respectively "... for example, /./dev/stdout or ///dev/stdout but not //dev/stdout (see 3.271 Pathname)." Anyway... if you think it's good as it is, I wouldn't insist on any of this (not that my opinion would count much anyway ^^).

The /dev/stdout syntax does not refer to a new special file." To (something like): "A special file /dev/stdout, that prints any data written to it to the respective process’ standard output, exists on most modern systems. The /dev/stdout syntax however does not refer to such special file." I think that would explain better what's happening there, perhaps one could even add that the special file, would still work as a "fallback" if some implementation "forgot" to handle the special name/magic cookie.

This has in principle already the potential of breaking things (namely, when some implementation didn't support '-' and someone really used it as the file '-'. But removing /dev/stdout, in the worst case, just breaks further things, namely when anyone relies on that being standard output and then it *might* not longer be so. And at best, removing it, doesn't give much advantage: - Implementations would just save one further string comparison. - They would allow to actually write to the file /dev/stdout... but on many systems, this will be anyway a special file that means standard output again,... and on all others... which use-case is there, for writing a /dev/ file from contents from uuencode? What I could agree, though, is if '-' would be named something like the "preferred" magic cookie. But I wouldn't deprecate /dev/stdout (as magic cookie)... most probably not even in the long term.

I'm not sure many implementations actually treat this as a special string and would just try to output to the actual device. As this device isn't specified by POSIX, it would look more logical to me to unspecify this part and let the user rely on the system implementation of /dev/stdout if provided, hence the deprecation. Using '-' as means of stdout looks like a more consistent solution.

I think it needs to be more prescriptive, not "do this or that". So for the L111240 replacement, I'd suggest something more like ... determine the pathname from the -o option if given, or if not, from the filename in the date. If that pathname is one of the magic cookies - or /dev/stdout then uudecode shall write the decoded file to standard output, otherwise it shall attempt to create or overwrite the file named by the pathname.

We should just say what we mean, and not be afraid of using more than one sentence, we don't pay a premium for using the '.' character. As I understand it, the intent is more like If the -o option is used, the pathname shall be outfile, otherwise the pathname is that encoded in the file data header by uuencode. If the pathname so determined is "-" or "/dev/stdout", output in the same format as the file originally encoded by uuencode shall be sent to standard output, otherwise standard output shall not be used. With the wording and formatting cleaned up to be nicer. Perhaps making the earlier text more clearly contain the first sentemce, and limiting the STDOUT section to simply the second (omitting "so determined" of course).

Solaris and macOS both create a file named "-" when "-o -" is specified, so the suggestion of disallowing this is unlikely to achieve consensus. I think the best we can do for now is to make it unspecified whether "-o -" means standard output or a file named "-", perhaps with an entry under FUTURE DIRECTIONS saying a future version may require it to mean standard output. Incidentally, the rationale is no longer correct when it says "The symbol - has only been used previously in POSIX.1-2017 as a standard input indicator", since the STDOUT section for uniq was changed in Issue 7 to say it is allowed to treat an output_file operand of "-" as meaning standard output.

The following issue has been SUBMITTED. == https://www.austingroupbugs.net/view.php?id=1544 == Reported By:calestyo Assigned To: == Project:1003.1(2016/18)/Issue7+TC2 Issue ID: 1544 Category: Shell and Utilities Type: Clarification Requested Severity: Editorial Priority: normal Status: New Name: Christoph Anton Mitterer Organization: User Reference: Section:uudecode Page Number:N/A Line Number:N/A Interp Status: --- Final Accepted Text: == Date Submitted: 2022-01-08 03:21 UTC Last Modified: 2022-01-08 03:21 UTC == Summary:uudecode: standardise or at least reserve - as another special symbol for decoding to stdout Description: As of now: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/uudecode.html doesn’t specify "-" as a special symbol for the -o option in order to print the decoded output to stdout, but only the special symbol '/dev/stdout' The rationale even explains: In early drafts, the [ -o outfile] option-argument allowed the use of - to mean standard output. The symbol - has only been used previously in POSIX.1-2017 as a standard input indicator. The standard developers did not wish to overload the meaning of - in this manner. The /dev/stdout concept exists on most modern systems. The /dev/stdout syntax does not refer to a new special file. It is just a magic cookie to specify standard output. Desired Action: The problem with that is that there is no strict guarantee that this file really exists or is available to the process. Imagine a chrooted process where /dev/ and /proc are not bind-mounted or take e.g. Debian's initramfs, where at least as of now, /dev/stdout doesn't exist as a file. IMO, the decision to use a file name as special symbol was rather unfortunate if not short sighted. I've seen at least one implementation which did not support '/dev/stdout' (as a special symbol until recently (busybox, and even now it depends on build configuration so it's not guaranteed to work). This can of course have the effect that output that should go to stdout, goes actually to a file /dev/stdout, if the implementation "forgot" about that speciality of POSIX, and the file doesn't exist as "special file" that also causes output to stdout. The problem is that this could of course cause leakage of sensitive data. At least GNU's uudecode and busybox' unconditionally support "-" as special symbol for -o. It may make sense to reserve "-" as well for that purpose (i.e. that conforming applications must not use it as literal filename) or even directly standardise it as such (i.e. that conforming implementations need to support it)). Of course this may break compatibility if anyone really used it in the sense of a actual filename. Alternatively a new option could be standardised, overriding -o and meaning write to stdout. I think POSIX should at least reserve == Issue History Date ModifiedUsername FieldChange == 2022-01-08 03:21 calestyo New Issue 2022-01-08 03:21 calestyo Name => Christoph Anton Mitterer 2022-01-08 03:21 calestyo Section => uudecode 2022-01-08 03:21 calestyo Page Number => N/A 2022-01-08 03:21 calestyo Line Number => N/A ==
