       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.

       --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.

       Remove the books identified by ids from the database. ids should be a comma separated list
       of id numbers (you can  get  id  numbers  by  using  the  search  command).  For  example,
       23,34,57-85 (when specifying a range, the last number in the range is not included).

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

       --permanent
              Ikke bruk søppelboksen

          calibredb add_format [options] id ebook_file

       Add the e-book in ebook_file to the available formats for the logical book  identified  by
       id.  You  can  get  id  by  using  the search command. If the format already exists, it is
       replaced, unless the do not replace option is specified.

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

       --dont-replace
              Do not replace the format if it already exists

REMOVE_FORMAT

          calibredb remove_format [options] id fmt

       Remove  the format fmt from the logical book identified by id. You can get id by using the
       search command. fmt should be a file extension like LRF or TXT or  EPUB.  If  the  logical
       book does not have fmt available, do nothing.

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

SHOW_METADATA

          calibredb show_metadata [options] id

       Show the metadata stored in the calibre database for the book identified by id.  id is  an
       id number from the search command.

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

       --as-opf
              Skriv ut metadata i OPF-format (XML)

SET_METADATA

          calibredb set_metadata [options] id [/path/to/metadata.opf]

       Set the metadata stored in the calibre database for the book identified by id from the OPF
       file  metadata.opf.  id  is an 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
              The  field to set. Format is field_name:value, for example: --field tags:tag1,tag2.
              Use --list-fields to get a list of all field names. You  can  specify  this  option
              multiple  times to set multiple fields. Note: For languages you must use the ISO639
              language codes (e.g. en for English, fr for French and so on). For identifiers, the
              syntax  is --field identifiers:isbn:XXXX,doi:YYYYY. For boolean (yes/no) fields use
              true and false or yes and no.

              List the metadata field names that can be used with the --field option

EXPORT

          calibredb export [options] ids

       Export the books specified by ids (a comma separated list) to the filesystem.  The  export
       operation  saves all formats of the book, its cover and metadata (in an opf file). You can
       get id numbers from the search command.

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

       --all  Eksporter alle bøker i databasen, ignorer ID listen.

SAVED_SEARCHES

          calibredb saved_searches [options] (list|add|remove)

       Manage the saved searches stored in this database.  If you try to add a query with a  name
       that already exists, it will be replaced.

       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 [valg] betegnelsesnavn på datatype

       Lag en standardkolonne.  betegnelsen er maskinens forenklede navn på kolonnen.  skal  ikke
       inneholde  mellomrom eller kolon. navnet er et forenklet navn på kolonnen.  datatype er en
       av: 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.  For  enumeration  columns,  use  --display"{\
              "enum_values\  ":[\ "val1\ ", \ "val2\ "]}" 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.

       --is-multiple
              Denne kolonnen lagrer data med emneord (f.eks. flerfoldige kommaseparerte verdier).

              Maksimal bredde for enkeltlinje i utdata. Standard er: Følg skjermstørrelse.

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  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

          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
              The maximum number of results to return. Default is all results.
