Dave Wells asked,
| Can anyone tell me what's wrong with this? I'm trying to split some old
| email archives into individual files while stripping unimportant header
| fields. From my shell I'm trying:
|
| % set FILENO=0000
As Philip said, you need setenv and another space where the equal sign is.
I don't know whether the syntax
VARIABLE=value command
in sh and its compatibles has an analogue for csh and its derivatives.
| followed by the real work:
| % formail < inputfile -k -X Date: -X From: -X To: -X Subject: -X
| In-Reply-To: -X X-Mailer: +1 -ds > $FILENO.txt
Aaron Schrab posted a solution that forks sh and cat for every message. It
can also be done by forking only procmail for every message:
setenv FILENO 0000
formail -kXDate: -XFrom: -XTo: -XSubject: -XIn-Reply-To: -XX-Mailer +1ds \
procmail -p DEFAULT=`pwd`/'$FILENO.txt' /dev/null < inputfile
or in a shell with sh-style syntax,
FILENO=0000 formail -kXDate: -XFrom: -XSubject: -XIn-Reply-To: -XX-Mailer \
-XTo: +1ds procmail -p DEFAULT=`pwd`/'$FILENO.txt' /dev/null < inputfile
The keys are to use procmail's -p option, to strong-quote '$FILENO' in the
setting of DEFAULT, and to use /dev/null or a known empty file as the rcfile.
