Synopsis

git mailsplit [-b] [-f<nn>] [-d<prec>] [--keep-cr] [--mboxrd]
                -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 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​.
