CALIBREDB(1)

NAME
calibredb - calibredb

calibredb command [opzioni] [argomenti]

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.

--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.

--username
    Nome utente per connettersi a un server di contenuto calibre

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"

ADD_CUSTOM_COLUMN

calibredb add_custom_column [opzioni] etichetta nome tipo

Crea una colonna personalizzata. etichetta è il nome amichevole della macchina della colonna. Non deve contenere spazi o punteggiatura. nome è il nome amichevole della colonna. tipo è uno di: bool, comments, composite, datetime, enumeration, float, int, rating, series, text

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

--display
    A dictionary of options to customize how the data in this column will be interpreted. This is a JSON string.

You will see the JSON for the "display" for the new column in the OPF.

--is-multiple
    Questa colonna salva i tag come dati (es. valori separati da virgole). Applicato solo se il tipo di dato è testo.

    Se la colonna salva più valori, aggiunge i valori specificati a quelli esistenti, altrimenti li sostituisce.

RESTORE_DATABASE

calibredb restore_database [options]

Restore this database from the metadata stored in OPF files in each directory of the calibre library. This is useful if your metadata.db file has been corrupted.

WARNING: This command completely regenerates your database. You will lose all saved searches, user categories, plugboards, stored per-book conversion settings, and custom recipes. Restored metadata will only be as accurate as what is found in the OPF files.

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

--item_count, -i
    Output only the number of items in a category instead of the counts per item within the category

--width, -w
    La larghezza massima di una singola riga nell'output. L'impostazione predefinita è quella di rilevare la dimensione dello schermo.

BACKUP_METADATA

calibredb backup_metadata [options]

Backup the metadata stored in the database into individual OPF files in each books directory. 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
    Di solito, questo comando opera solo su libri che hanno file OPF datati. Questa opzione lo applica a tutti i libri.

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
    Aggiorna i metadata nei file del formato selezionato. Specificarlo diverse volte per formati multipli. Di default vengono aggiornati tutti i formati.

SEARCH

calibredb search [options] search expression

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: author:asimov title: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
    Il numero massimo di risultati da fornire. Tutti i risultati sono il default.
