NOTMUCH-RESTORE(1)

NAME
notmuch-restore - restores the tags from the given file (see notmuch dump)

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.

--include=(config|properties|tags)
    Control what kind of metadata is restored.

config
    Restore configuration data to the database. Each configuration line starts with "#@ ", followed by a space separated key-value pair. Both key and value are hex encoded if needed.

properties
    Restore per-message (key,value) metadata. Each line starts with "#= ", followed by a message id, and a space separated list of key=value pairs. Ids, keys and values are hex encoded if needed. See notmuch-properties(7) for more details.

tags
    Restore per-message metadata, namely tags. See format above for more details.

    The default is to restore all available types of data. The option can be specified multiple times to select some subset.

--input=<filename>
    Read input from given file instead of stdin.

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.
