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.

--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
Username for connecting to a calibre Content server

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 [options] label name datatype
Create a custom column. label is the machine friendly name of the column. Should not contain spaces or
colons. name is the human friendly name of the column. datatype is one of: bool, comments, composite,

Whenever you pass arguments to calibredb that have spaces in them, enclose the arguments in quotation

There are many options that can go into the display variable.The options by column type are:
composite: composite_template, composite_sort, make_category,contains_html, use_decorations
datetime: date_format enumeration: enum_values, enum_colors, use_decorations int, float:
number_format text: is_names, use_decorations The best way to find legal combinations is to
create a custom column of the appropriate type in the GUI then look at the backup OPF for a book
(ensure that a new OPF has been created since the column was added). You will see the JSON for the
"display" for the new column in the OPF.

If the column stores multiple values, append the specified values to the existing ones, instead of
replacing them.
