Usage of /usr/bin/rmail

This is almost certainly a trivial question, but unfortunately my system doesn't have the manual pages for rmail. When I try the following command:

echo "localhost myname" | rmail myname

I expected mail to be posted back to myself. Instead, I got the message: "missing or empty From line". What format changes do I need to make?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

rmail is for recieving mail

echo "localhost myname" | mail myname

should do it.  you can add a "-s" to put a subject on it.

echo "localhost myname" | mail myname -s "It worked!"

Take Care,

Thanks for answering my question, but I won't grade it as yet. For a start, I'd be interested to know what the machine is expecting when it says "missing or empty From line". What would I have to add to the line I gave so that that message did not come up?

My second comment is that my system doesn't like the -s flag. It says "illegal option".

Thanks,

ventnor

All of the research I have done on mail agree that -s is real.  Possibly, your sysadmin has tweaked things a bit.

As far as rmail, I'm not quit sure why you would want to use it.  Most of the URL's I found talked about using it with emacs (as a wrapper?).  Here are 2 good sites that I found:
http://mmg2.im.med.umich.edu/~kcheek/texi-docs/xemacs/rmail_2.html
http://sunland.gsfc.nasa.gov/info/emacs/Rmail_Reply.html

note that both have "emacs" in the path.

Have fun, and good luck!

The Linux system is my own, so it hasn't been tweaked at all. I shan't grade this question, as it still hasn't really been answered.
