CALIBREDB(1)

NAME
calibredb - calibredb

            calibredb command [options] [arguments]

calibredb is the command line interface to the calibre database. It has several sub-commands, documented below.

calibredb can be used to manipulate either a calibre database specified by path or a calibre Content server running either on the local machine or over the internet. You can start a calibre Content server using either the calibre-server program or in the main calibre program click Connect/share  → Start Content server. Since calibredb can make changes to your calibre libraries, you must setup authentication on the server first. There are two ways to do that:

            •   If you plan to connect only to a server running on the same computer, you can simply use the --enable-local-write option of the Content server, to allow any program, including calibredb, running on the local computer to make changes to your calibre data. When running the server from the main calibre program, this option is in Preferences → Sharing over the net → Advanced.

            •   If you want to enable access over the internet, then you should setup user accounts on the server and use the --username and --password options to calibredb to give it access. You can setup user authentication for calibre-server by using the --enable-auth option and using --manage-users to create the user accounts. If you are running the server from the main calibre program, use Preferences → Sharing over the net → Require username/password.

To connect to a running Content server, pass the URL of the server to the --with-library option, see the documentation of that option for details and examples.

GLOBAL OPTIONS

    --help, -h
        show this help message and exit

    --library-path, --with-library
        Path to the calibre library. Default is to use the path stored in the settings. You can also connect to a calibre Content server to perform actions on remote libraries. To do so use a URL of the form: <http://hostname:port/#library_id> for example, <http://localhost:8080/#mylibrary>. library_id is the library id of the library you want to connect to on the Content server. You can use the special library_id value of - to get a list of library ids available on the server. For details on how to setup access via a Content server, see <https://manual.calibre-ebook.com/generated/en/calibredb.html>.

    --password
        Password for connecting to a calibre Content server. To read the password from standard input, use the special value: <stdin>. To read the password from a file, use: <f:/path/to/file> (i.e. <f: followed by the full path to the file and a trailing >). The angle brackets in the above are required, remember to escape them or use quotes for your shell.

    --timeout
        The timeout, in seconds, when connecting to a calibre library over the network. The default is two minutes.

    --username
        Username for connecting to a calibre Content server

    --version
        show program's version number and exit

Set the metadata stored in the calibre database for the book identified by book_id from the OPF file metadata.opf. book_id is a book id number from the search command. You can get a quick feel for the OPF format by using the --as-opf switch to the show_metadata command. You can also set the metadata of individual fields with the --field option. If you use the --field option, there is no need to specify an OPF file.

Whenever you pass arguments to calibredb that have spaces in them, enclose the arguments in quotation marks. For example: "/some path/with spaces"

    --field, -f

    --dont-update-metadata
        Normally, calibre will update the metadata in the saved files from what is in the calibre library. Makes saving to disk slower. Specifying this switch will turn this behavior off.

    --dont-write-opf
        Normally, calibre will write the metadata into a separate OPF file along with the actual e-book files. Specifying this switch will turn this behavior off.

    --formats
        Comma separated list of formats to save for each book. By default all available formats are saved.

    --progress
        Report progress

    --replace-whitespace

Syntax for adding:

calibredb saved_searches add search_name search_expression

Syntax for removing:

calibredb saved_searches remove search_name

Whenever you pass arguments to calibredb that have spaces in them, enclose the arguments in quotation marks. For example: "/some path/with spaces"

BACKUP_METADATA

            calibredb backup_metadata [options]

Backup the metadata stored in the database into individual OPF files in each books folder. This normally happens automatically, but you can run this command to force re-generation of the OPF files, with the --all option.

Note that there is normally no need to do this, as the OPF files are backed up automatically, every time metadata is changed.

Whenever you pass arguments to calibredb that have spaces in them, enclose the arguments in quotation marks. For example: "/some path/with spaces"

    --all
        Normally, this command only operates on books that have out of date OPF files. This option makes it operate on all books.

CLONE

            calibredb clone path/to/new/library

Create a clone of the current library. This creates a new, empty library that has all the same custom columns, Virtual libraries and other settings as the current library.

The cloned library will contain no books. If you want to create a full duplicate, including all books, then simply use your filesystem tools to copy the library folder.

Whenever you pass arguments to calibredb that have spaces in them, enclose the arguments in quotation marks. For example: "/some path/with spaces"

EMBED_METADATA

            calibredb embed_metadata [options] book_id

Update the metadata in the actual book files stored in the calibre library from the metadata in the calibre database. Normally, metadata is updated only when exporting files from calibre, this command is useful if you want the files to be updated in place. Note that different file formats support different amounts of metadata. You can use the special value 'all' for book_id to update metadata in all books. You can also specify many book ids separated by spaces and id ranges separated by hyphens. For example: calibredb embed_metadata 1 2 10-15 23

Whenever you pass arguments to calibredb that have spaces in them, enclose the arguments in quotation marks. For example: "/some path/with spaces"

    --only-formats, -f
        Only update metadata in files of the specified format. Specify it multiple times for multiple formats. By default, all formats are updated.

SEARCH

Search the library for the specified search term, returning a comma separated list of book ids matching the search expression. The output format is useful to feed into other commands that accept a list of ids as input.

The search expression can be anything from calibre's powerful search query language, for example: calibredb search author:asimov 'title:"i robot"'

Whenever you pass arguments to calibredb that have spaces in them, enclose the arguments in quotation marks. For example: "/some path/with spaces"

    --limit, -l
        The maximum number of results to return. Default is all results.

FTS_INDEX

            calibredb fts_index [options] enable/disable/status/reindex

Control the Full text search indexing process.

    enable
        Turns on FTS indexing for this library

        Shows the current indexing status

    reindex
        Can be used to re-index either particular books or the entire library. To re-index particular books specify the book ids as additional arguments after the reindex command. If no book ids are specified the entire library is re-indexed.

Whenever you pass arguments to calibredb that have spaces in them, enclose the arguments in quotation marks. For example: "/some path/with spaces"

    --indexing-speed
        The speed of indexing. Use fast for fast indexing using all your computers resources and slow for less resource intensive indexing. Note that the speed is reset to slow after every invocation.

    --wait-for-completion
        Wait till all books are indexed, showing indexing progress periodically

FTS_SEARCH

            calibredb fts_search [options] search expression

Do a full text search on the entire library or a subset of it.

Whenever you pass arguments to calibredb that have spaces in them, enclose the arguments in quotation marks. For example: "/some path/with spaces"

    --do-not-match-on-related-words
        Only match on exact words not related words. So correction will not match correcting.

    --include-snippets
        Include snippets of the text surrounding each match. Note that this makes searching much slower.

    --indexing-threshold
        How much of the library must be indexed before searching is allowed, as a percentage. Defaults to 90

    --match-end-marker
        The marker used to indicate the end of a matched word inside a snippet

    --match-start-marker
        The marker used to indicate the start of a matched word inside a snippet

    --output-format
        The format to output the search results in. Either "text" for plain text or "json" for JSON output.

    --restrict-to
        Restrict the searched books, either using a search expression or ids. For example: ids:1,2,3 to restrict by ids or search:tag:foo to restrict to books having the tag foo.
