Calibre instalado no Flatpak: não é possível encontrar o comando ebook-convert

  • 772

No meu Linux Mint 22 Cinnamon (Wilma) baseado no Ubuntu 24.04 LTS (Noble).

Acabei instalando o Calibre apesar da minha antipatia inicial, via Flatpak:

$ flatpak install flathub com.calibre_ebook.calibre

A instalação foi bem-sucedida, mas o shell não consegue encontrar o ebook-convertcomando ( link da página do manual oficial ).

Motivo da escolha da versão Flatpak:

Neste momento, lendo o changelog aqui: https://calibre-ebook.com/whats-new

É óbvio que o(s) desenvolvedor(es) são muito ativos. A versão empacotada é Release: 7.6 [01 Mar, 2024], enquanto a versão Flatpak é a mais recente disponível (Release: 7.20 [18 Out, 2024]).

Apesar de eu ter pensado inicialmente que usaria apenas o comando de conversão de e-books, este software pode me surpreender .

    Uma maneira de fazer isso:

    $ sudo updatedb
[sudo] password for vlastimil:

# - No output means it is still running.
# - Once it is finished, your prompt re-appears.
# - It can take much time if not running fast SSDs.

    $ locate ebook-convert

    Lá você pode ver duas opções. Se você tentar esta, você obtém um erro, mas a segunda funciona:

    /var/lib/flatpak/app/com.calibre_ebook.calibre/x86_64/stable/3ffcc2f6b264f6549554e88892c32eb48cd83386b8629e839bb693d2010aeaa6/files/lib/calibre /bin/ ebook-convert: erro ao carregar bibliotecas compartilhadas: libcalibre-launcher.so: não é possível abrir o arquivo de objeto compartilhado : Nenhum arquivo ou diretório desse tipo

    Como estou usando Bash, posso simplesmente criar um alias para o arquivo correto (ou seja, sem /bin/antes ebook-convert) assim:

    alias ebook-convert='/var/lib/flatpak/app/com.calibre_ebook.calibre/x86_64/stable/3ffcc2f6b264f6549554e88892c32eb48cd83386b8629e839bb693d2010aeaa6/files/lib/calibre/ebook-convert'

    Comando de trabalho:

    $ ebook-convert

Usage: ebook-convert input_file output_file [options]

Convert an e-book from one format to another.

input_file is the input and output_file is the output. Both must be specified as the first two arguments to the command.

The output e-book format is guessed from the file extension of output_file. output_file can also be of the special format .EXT where EXT is the output file extension. In this case, the name of the output file is derived from the name of the input file. Note that the filenames must not start with a hyphen. Finally, if output_file has no extension, then it is treated as a folder and an "open e-book" (OEB) consisting of HTML files is written to that folder. These files are the files that would normally have been passed to the output plugin.

After specifying the input and output file you can customize the conversion by specifying various options. The available options depend on the input and output file types. To get help on them specify the input and output file and then use the -h option.

For full documentation of the conversion system see
https://manual.calibre-ebook.com/conversion.html

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

Options:
  --version       show program's version number and exit

  -h, --help      show this help message and exit

  --list-recipes  List builtin recipe names. You can create an e-book from a
                  builtin recipe like this: ebook-convert "Recipe Name.recipe"
                  output.epub
