# splitmail++(1)

split mailbox files prior to indexing

## NAME

splitmail++ - split mailbox files prior to indexing

## SYNOPSIS

**splitmail++ -p*prefix*** **\[** *file* **\]**

## DESCRIPTION

**splitmail++** is a utility to split a mailbox file (or standard input) comprised of multiple messages into multiple files of individual messages to facilitate indexing with [**index++**(1)](/index++/1.md). The generated files have 5-digit increasing numbers appended to a common prefix. If the mailbox file has some non-mail header, then this is dumped to a file with the same prefix and `_junk_header` as the suffix.

## OPTIONS

- **-p***prefix*

  Specifies the common prefix.

## EXAMPLE

The command:

```
splitmail++ -p msg sent_messages
```

splits the mailbox `sent_messages` into files named `msg.00001`, `msg.00002`, and so on. Any non-mail header gets dumped to a file named `msg_junk_header`.

## NOTE

This utility hasn't been exhaustively tested.

## SEE ALSO

[**index++**(1)](/index++/1.md).
