I would like to grep a specific line out of a mail or news message and
append it to a file. The messages are essentially boilerplate containing a
single action line that I need to collect and feed to a shell script.
I've tried Washing->Unix pipe and Output->pipe through a filter, but I
can't seem to get either to do what I want. Has anybody done this? Could
I get a look at your code?
Ideally I would like to use nnml-split or -split-fancy to automate the
process. Any suggestions would be welcome.

Doesn't something like
M-| grep stuff >> file
work?

Hmm. I get either 'There is no region now' or "Shell command completed
with no output' depending on where point is.
If I use 'Output->pipe through a filter' to a one-liner containing my grep
statement, I get the message body cleaned of everything except the line I'm
after, but that's not what I need. What I need is to send that line out to
a file. I'm getting a couple dozen of these emails a day and I need to
collect those lines so I can feed them into a shell script about once a
day.
Aarrgh. I've learned just enough about [X]emacs and gnus and lisp to know
the power is there if I can just figure it out...

| grep foo >> /tmp/bar RET
The above, when typed from the summary buffer, should append all lines
matching foo to the file /tmp/bar.

Opps. It should be a simple "|", not a meta-|

Right, thats what the ">> file" part should do.

No joy, Kai. I understand that vertical bar to mean M-|, yes? I get
'There is no region now'. If I use | without Meta, I get 'Wrong type
argument: stringp nil'. I also tried marking all articles first, but that
didn't help either.

I typed `|', I meant `|' :-) What does C-h c | tell you when typed in
a Gnus summary buffer? For me, it says it runs the command
gnus-summary-pipe-output. If it is different for you, that might be a
problem.
I use that command and a shell script `gnusprint' all the time for
printing articles from Gnus, so I'm *pretty* sure `|' works for me.
Just for fun, could you `emacs -q -no-site-file' then start Gnus then
see whether `|' works. The `-q' means don't load ~/.emacs, the
`-no-site-file' means don't load site-start.el. Omitting one of the
two arguments loads the respective file, this way you can narrow down
where the problem might be.
(For starting Gnus in `emacs -q -no-site-file' you might have to do
some setup by hand, such as setting the nntp server and stuff. Try to
keep that to a minimum, though.)

It is defined as gnus-summary-pipe-output.

I spent some time with this. By temporarily renaming my startup files one
by one I've narrowed it down a little more. My .emacs seems to be OK. If
I rename .gnus AND .xemacs-options I'm OK. If I load either .gnus OR
.xemacs-options, I get 'Wrong type argument: stringp, nil'. The backtraces
in either case appear to be identical except for the tmp buffer name.
I've been through both files and I don't see anything obviously wrong. But
then, I don't really know what I'm looking for.
Backtrace with .gnus loaded follows. I hope that's OK.

You seem to have filled the backtrace, which makes it rather difficult
to read, but:
> shell-command-on-region(1 3244 nil nil) gnus-summary-save-in-pipe(default)
gnus-summary-save-in-pipe is called with `default' as the parameter.
Do you have gnus-prompt-before-saving set to nil?

Oops. Didn't intend to. I guess when I snipped and filled Kai's comments
my ever-helpful gnus did the backtrace too.

Yes I did, although I don't remember when or why. Changed to t and pipe
works as advertised. Thank you.

But I think gnus-prompt-before-saving set to nil shouldn't break the
gnus-summary-save-in-pipe command. The problem is that
gnus-summary-save-in-pipe doesn't have a default default value.
Perhaps I could just default to "cat"? Eh.
