calibredb - calibredb
calibredb kommando [valgmuligheter] [argumenter]
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.

GLOBALE INSTILLINGER
--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

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:

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.

Control the Full text search indexing process.
enable Turns on FTS indexing for this library
disable
Turns off FTS indexing for this library
status 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
Vent til alle bøker er indeksert, viser indekseringsfremdrift fortløpende
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"

90
--match-end-marker
The marker used to indicate the end of a matched word inside a snippet
--match-start-marker
