} no, but you can save outgoing mail headers only using "set logfile = ..."

"NO?"  Not feeling terribly helpful today, Dan? :-)	[%]

Of course you can save just the headers, you just can't do it with the
"save" command.

Try

    mush> pipe sed -n 1,/\^\$/p >> file

If you want a message list rather than the current message, the list goes
between the "pipe" and the "sed".  Note that the Bourne shell, which is
run by the "pipe" command, is performing the >> redirection; mush doesn't
do that itself. [%%]

"pipe" does not write the ignored headers ("ignore" command or "show_hdrs"
variable).  If you want to save ALL the headers, you have to do a little
more work:

    mush> set print_cmd='sed -n 1,/\^\$/p >> file'
    mush> lpr
    printing message 11...(219 lines)
    1 message printed through "sed -n 1,/\^\$/p >> file".
    mush> unset print_cmd

You can of course bundle all this up into a "cmd" alias (the quoting is a
bit nasty, escaped newlines for readability):

    cmd sv_hdrs "\
	    set sv_list ;\
	    set print_cmd='"'sed -n 1,/\^\$/p >> \!:$'"'"' ;\
	    lpr $sv_list \!* ;\
	    unset sv_list print_cmd'

Some non-obvious things going on here.  I'll explain the mush ones, sed
is up to you:

    set sv_list	
		This exploits a special feature of the "set" command
		to allow you to pipe to sv_hdrs.  For example,
		    pick mush-users | sv_hdrs mu-hdrs
		expands to
		    pick mush-users | set sv_list ; set print_cmd=...
		and $sv_list gets set to the messages found by pick.

    set print_cmd='sed -n 1,/\^\$/p >> \!:$'
		The \!:$ sets the file name to the last argument on the
		sv_hdrs command line, for compatibility with "save".
		YOU MUST GIVE A FILE NAME!  Otherwise you will either
		get an error or the message list will be used as a file
		name, which probably is not what you want.

    lpr $sv_list \!*
		The \!:* picks up any message list that was given before
		the file name.  It also picks up the file name, but the
		"lpr" command conveniently ignores that.  The $sv_list
		spits out whatever messages were piped to sv_hdrs.  So
		all messages listed and piped get their headers saved.

I think that about covers it. :-)  Hope it helps.	[+]

   completely wrong.

%% The characters < and > are used in E-mail addresses, so mush avoids
   using them as redirection metachars.
