Bug ID: 271127 Summary: man-page for mail(1)/mailx(1) doesn't document :r and friends Product: Documentation Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Manual Pages Assignee: b...@freebsd.org Reporter: free...@tim.thechases.com CC: d...@freebsd.org Invoking mail(1), you can specify messages such as & f :u (to list unread messages) or & p :o (to print Old messages) or & d :r (to delete messages that have been read), etc. So they work, but AFAICT, there's no documentation on them in the man-page $ man mail | grep ':r' I imagine the text can be cribbed from [OpenBSD's man-pages for `mail(1)`](https://man.openbsd.org/mail.1#Specifying_messages) -- You are receiving this mail because: You are the assignee for the bug.
