NAME
calibredb - calibredb
calibredb príkaz [možnosti] [parametre]
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.

--help, -h

--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.

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 Normálne tento príkaz funguje iba u kníh, ktoré majú zastarané súbory OPF. Táto
možnosť umožňuje fungovanie u všetkých kníh.
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"

for multiple formats. By default, all formats are updated.
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: 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
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
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.
