Don't some weird systems move by copying & deleting ? This happens anyway when
you move between filesystems (though they probably won't share quota).

I knew about piping to mail/mailx/mutt (unix of course ...), but my question
was about, e.g.:

% cat | mutt -a -
-: unable to attach file.

Thought I could be too lazy to add another pipe, for uuencode'ing :-)

Sure, no problem for me either, but on the system I know.

I would not have bet, since I even managed to fill a filesystem using a named
pipe (though not the one the pipe was on; don't know enough about how those
beings are actually implemented). My advice in the present case, after mailing
myself an 9MB file for fun: use mail/mailx for that kind of joke ...

% uuencode USER_GDE.PS2 USER_GDE.PS2 | wc -c
% uuencode USER_GDE.PS2 USER_GDE.PS2 | mutt munhoven
[and keep an eye on /tmp; that's why 9MB; keep it buzy a moment]
% ls -l /tmp
-rw-------   1 munhoven system   12285521 Nov 12 23:56 mutt-cezanne-16633-0
-rw-------   1 munhoven system   12285787 Nov 12 23:56 mutt-cezanne-16633-1
-rw-------   1 munhoven system   12285521 Nov 12 23:56 mutt-cezanne-16633-2

Oops. With another file of similar size in /var/spool/mqueue, but that one
belongs to root :-)

In any case will the file be completely downloaded before being eventually
piped to mail. lynx is simply not the most appropriate tool to solve the
problem described. Perhaps rather:

% wget -O - | mailx address@hidden

would do it on my system (but on the original request system ?).
