O.K., I'm tired of wondering...
Why does System V version 2,3 not have a recursive copy routine (cp -r)?
It would seem like that is something that one would want to do without
too much trouble.
Why does the System V mailer (mailx) not provide for forwarding and
responding to mail messages (f and r)?

"mailx", being based on a 4.1BSD-vintage Berkeley Mail, most definitely *does* have the "r" command. "mail" doesn't, but then "mail" on 4BSD systems (a/k/a "binmail") doesn't either. They don't have it because the V7 "mail" didn't have it, and people have put their effort into other mailers rather than adding stuff to "mail". The V7 "mail" probably doesn't have it because people didn't get as much mail back in ancient times, so they didn't miss them as much. The "f" command is the "from" command, just as it is in 4BSD "Mail". In both 4BSD "Mail" and "mailx", you forward mail with the "mail" command.

Perhaps because it has more flexible facilities via find -cpio|cpio -p. The trouble with "cp -r" and similar "nice" features is that they ASSUME A PARTICULAR USAGE MODEL that is not always appropriate. Better to provide tailorable facilities and let the users decide how to use them for their parcticular purposes. (If I felt much need for it, which I don't, I would defined a shell function "cpr" to do a recursive copy.)

I do it all the time. When you read your mail and get the "?" prompt, if you enter an "r" you'll be replying to the original sender as well as to everyone to whom the message you are replying to was sent; if you enter an "R" you are replying to the original sender only. As for forwarding, try entering an "R", editing the header (with "~h") to change the "To:" line to contain the address you want to forward to, and then include the message by entering "~f". Works every time. Are you sure you've got System V mailx ... ?

(Leave off the -l flag to cpio to force copies.) You can always write a shell script to do this. +--------------- | Why does the System V mailer (mailx) not provide for forwarding and | responding to mail messages (f and r)? +--------------- There are at least two reply commands: 'r' and 'R'. As for forwarding, the reason is lost in the antiquities of 4.1BSD (yes, indeed, System V mailx is actually Berkeley Mail); the proper way to forward mail is: Mailx> mail foo Subject: forwarded mail ~f .

Actually, mailx in system V does have a forward command. It's under the tilde escapes and is described in the SVID. You have to be entering text for the letter to use the tilde escape su just mail to the users you want to forward to and then use "~f <msglist>".Z
