GIT-MAILSPLIT(1) Git Manual GIT-MAILSPLIT(1)NAME
git-mailsplit - Simple UNIX mbox splitter program
SYNOPSIS
git mailsplit [-b] [-f<nn>] [-d<prec>] [--keep-cr] -o<directory> [--] [(<mbox>|<Maildir>)...]
DESCRIPTION
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.
OPTIONS
<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
from lines ending with
.
