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.

       --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.

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 [voľby] označenie názov typdát

       Vytvorí vlastný stĺpec.  označenie je názov stĺpca pre počítač. Nesmie obsahovať medzery a
       dvojbodky.  názov je názov stĺpca pre ľudí.  typdát je jedno z: 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
              Tetnto stĺpec obsahuje údaje typu značky (tzn. viac  hodnôt  oddelených  čiarkami).

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.
