git-mailsplit - Simple UNIX mbox splitter program

       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.

       Part of the git(1) suite

       git-mailsplit - Simple UNIX mbox splitter program

       <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
           an 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.
