SYNOPSIS
========
**notmuch** **restore** [--accumulate] [--format=(auto|batch-tag|sup)] [--input=<*filename*>]
DESCRIPTION
===========
Restores the tags from the given file (see **notmuch dump**).
The input is read from the given filename, if any, or from stdin.
Supported options for **restore** include
``--accumulate``
The union of the existing and new tags is applied, instead of
replacing each message's tags as they are read in from the dump
file.
``--format=(sup|batch-tag|auto)``
Notmuch restore supports two plain text dump formats, with each
line specifying a message-id and a set of tags. For details of
the actual formats, see **notmuch-dump(1)**.
**sup**
The **sup** dump file format is specifically chosen to be
compatible with the format of files produced by sup-dump. So
if you've previously been using sup for mail, then the
**notmuch restore** command provides you a way to import all
of your tags (or labels as sup calls them).
**batch-tag**
The **batch-tag** dump format is intended to more robust
against malformed message-ids and tags containing whitespace
or non-\ **ascii(7)** characters. See **notmuch-dump(1)**
for details on this format.
**notmuch restore** updates the maildir flags according to
tag changes if the **maildir.synchronize\_flags**
configuration option is enabled. See **notmuch-config(1)**
for details.
**auto**
This option (the default) tries to guess the format from the
input. For correctly formed input in either supported
format, this heuristic, based the fact that batch-tag format
contains no parentheses, should be accurate.
GZIPPED INPUT
=============
\ **notmuch restore** will detect if the input is compressed in
**gzip(1)** format and automatically decompress it while reading. This
detection does not depend on file naming and in particular works for
standard input.
