i'm trying to write a script to convert pegasus mail-style
mailboxes into the normal unix mbox format, and am having a few problems,
at least one of which i think is shell-related. i want to use formail to
reformat each message, but since pmail uses the ^Z char as its message
delimiter, formail only sees one large message per mailbox, so i'm now
trying to find a way to split out the messages and pass each one to
formail separately. someone pointed me to csplit for that, and as far
as i can tell, it's what i want:
$ csplit -sk -n4 pmailbox.PMM /$ZZZ/ {9999}
, where ZZZ is defined as the ^Z char (which i had to do because the
telnet program i'm currently using interprets the ^Z as a suspend, even
if i precede it with a ^V to escape it for the shell), should create a
new file for each message in pmailbox.PMM, up to 9999 of them. instead,
i get 100 messages split out, and then csplit returns the error in my
subject line. is this a shell or kernel paramater (i think i read somewhere
about a max # of files that a single process could create), or something
else entirely?
tia,
sweth.

The csplit program simply refuses to create more than 100 output files.
The limit you're thinking of is the maximum number of files that a process
can have -open- at the same time; I doubt csplit is keeping all 100 files
open, so that's not likely to be the problem.

Is that the only reason formail sees only one message? What's the text
immediately following each ^Z? You might be able to get away with using
sed to replace the ^Z with something formail will recognize. Also, have
you tried "formail -d" ?
} so i'm now
} trying to find a way to split out the messages and pass each one to

Got perl?
perl -p032 -e 'close(STDOUT); s/.$//; open(STDOUT, "|formail >> mboxfile");'
(That assumes that the last message is not followed by a ^Z. If it is,
you'll get one extra "From " line at the end of mboxfile. It also assumes
you've got enough memory to have perl slurp up an entire message before it
sends any output to formail.)
