git-mailsplit - Simple UNIX mbox splitter program
git mailsplit [-b] [-f<nn>] [-d<prec>] [--keep-cr] [--mboxrd]
-o<directory> [--] [(<mbox>|<Maildir>)...]
Splits a mbox file or a Maildir into a list of files:
"0001" "0002" .. in the specified directory so you can
process them further from there.
Important
Maildir splitting relies upon filenames being sorted to output
patches in the correct order.
<mbox>
Mbox file to split. If not given, the mbox is read from
the standard input.
<Maildir>
Root of the Maildir to split. This directory should
contain the cur, tmp and new subdirectories.
-o<directory>
Directory in which to place the individual
messages.
-b
If any file doesn’t begin with a From line, assume
it is a single mail message instead of signaling error.
-d<prec>
Instead of the default 4 digits with leading zeros,
different precision can be specified for the generated filenames.
-f<nn>
Skip the first <nn> numbers, for example if -f3 is
specified, start the numbering with 0004.
--keep-cr
Do not remove \r from lines ending with
\r\n.
--mboxrd
Input is of the "mboxrd" format and
"^>+From " line escaping is reversed.
