| Summary | 0000999: Forbid `Save' command in startup file | ||||
| Description | I don't understand why `Copy' is forbidden during startup but `Save' is not. It is not documented but i think `copy' etc. are not forbidden because they don't (necessarily) require knowledge of message content (except message boundary detection), whereas the uppercase versions have content inspection as a precondition (to derive the target filename). If this is indeed the reason, then `Save' (added in Issue 6) is missing from the list. | ||||
| Desired Action | Change the sentence on p. 2915 l. 96280 ff. from The following commands shall be invalid in the start-up file: !, edit, hold, mail, preserve, reply, Reply, shell, visual, Copy, followup, and Followup. to The following commands shall be invalid in the start-up file: !, edit, hold, mail, preserve, reply, Reply, Save, shell, visual, Copy, followup, and Followup. | ||||

Although Copy and Save were added to POSIX in 2001, they came in via SUS where they were UNIX extensions to POSIX. Before SUS they were in XPG, and XPG took them from SVID. And SVID2 (the earliest I have, 1986) forbade Copy in start-up files but not Save. I don't know why, but it's always been that way. |

Ah, ok. So likely no technical reason but only tradition. Thanks! P.S., for the record: for BSD Mail the actual source code as of 2BSD (1979-04) forbids the following commands when "sourcing" (in cmdtab order) visual, mail, !, reply, respond, edit, 3BSD (1980-03) adds shell, Reply, Respond Finally (i still miss the intermediates) mailx 8.1[.1] as of 1996-06-14 knows about `save' and `copy' but doesn't forbid them "when sourcing". Nor does it forbid `hold' / `preserve'. It doesn't know about sending follow up mails yet. |

Interpretation response ------------------------ The standard states that Save is processed during mail startup, and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor. Rationale: ------------- This is not the way historic implementations work. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- Make the changes suggested in the Desired Action. |
