Ok. This may seem a silly question, but I have RTFM'd, and I can't see
an easy + simplistic answer.

I want to include the output from a shell command in a header.
Say I wanted to produce a header like

X-My-Date: Fri Sep 21 09:53:09 BST 1990
where
this would be the output from something approaching
my_hdr X-My-Date: `sh date`

How would I go about it?
What I have tried is using a shell function as a workaround, in the hope
of someone providing me a better solution.

mush()
{
	tmpfile=/tmp/mu.$$
	echo my_hdr X-My-Date: `date` > $tmpfile
	/usr/local/bin/mush -C -F $tmpfile $*
	rm $tmpfile
}

Even this doesn't work properly. It adds the extra header as long as you
enter the shell before you start sending mail. I've tried things like
testing is_sending, but that doesn't seem to work either.

Any ideas? I'm running Mush 7.1.2 under Sco Xenix 2.3.1. Here is my .mushrc
-----
if hdrs_only
	exit
endif

set realname='Matthew Farwell'
set record=+outgoing
my_hdr X-Bogus-Mail-Header: Strawberry shortcake
my_hdr X-Coffee-Cup: Sun Microsystems
# some aliases here...
bind '=' macro '(~/mail/savelists\n'

Dylan.

p.s. `date` is only used as an example. I want a generic way of doing things.
