[9fans] sam -d reading from stdin?

[Matthias Teege]

Moin,

I use the following in pipefrom to get the
content of the Reply-To header from an
outgoing Email.

cat > $TMP
replyto=`{echo ', x/(.+\n)+/ g/^[Rr]eply-[Tt]o:.*/ p' | sam -d $TMP >[2] /dev/null | tr A-Z a-z | grep reply-to | sed 's/reply-to: *//'}

Is there any way to avoid the creation of
a temporary file? Can I read from stdin
with sam -d?

Second question. Is there any way to make
g/^[Rr]eply-[Tt]o:.*/ case insensitive
without using [Rr] constructs?

How about

	tee /fd/2 |[2] {tr A-Z a-z | sed -n 's/^reply-to: *//p
/^$/q'} >/env/x

Well, its a temp file but just the environmnt one you had anyways.  You can't use
$x later in the script because the shell won't have noticed that you changed an
env variable...

The /^$/q just gets you out when the message starts so you don't snarf any body
messages

This is how I use sam -d in a pipeline, taken from an existing shell script:

tcs -f msdos <$file |[3=1] sam -d /fd/3 <<'!' >[2]/dev/null
,x/
+$/ d
,x/
+/ x/
/ c/\n/
w /fd/1
!

Whoops, that script won't make much sense, since the carriage returns
(ascii or utf 015) got turned into newlines (ascii or utf 012).  If
you replace each ~ with a carriage return, the script should look like
this:

tcs -f msdos <$file |[3=1] sam -d /fd/3 <<'!' >[2]/dev/null
,x/~+$/ d
,x/~+/ x/~/ c/\n/
w /fd/1
!

true, but that's not the point.  you don't need rep.

i posted it as an example of how to use sam.

rep just repl[lies] to an rfc 822 message by
creating a reply template in a file.
