Show metadata of an EPUB file
Usage: epubinfo [options] EPUBFILE
-f, --format=FORMAT format of output(line, json or yaml), defaults to line(for console)
--words count words of content documents
--chars count charactors of content documents
--navigation[=TYPE] show specified type of navigation(toc, page-list or landmarks)
If TYPE is omitted, show all types of navigations.
Can specify multiple times.
--toc show table of contents navigation(in line format only)
--page-list show page list navigation(in line format only)
--landmarks show landmarks navigation(in line format only)
Output formats
epubinfo can output in three formats: line, JSON and YAML. You can specify format by --format(-f) command-line option
JSON
$ epubinfo --format=json ~/Documebts/Books/build_awesome_command_line_applications_in_ruby_fo.epub | jq .

Character and word count
epubinfo can count characters and words(space perarated) in EPUB document. Pass --chars and --words options to the command.
Note that this makes process slower because it will read all the document.
$ epubinfo --chars --words ~/Documebts/Books/build_awesome_command_line_applications_in_ruby_fo.epub

Part I. Part C Core
If you need only one type of navigation, tell it to navigation option:
% epubinfo --navigation=toc ./linear-algebra.epub
You can specify multiple typs by pass the option multiple times:
% epubinfo --navigation=toc --navigation=landmarks ./linear-algebra.epub
Short cut options --toc, --page-list and --landmarks are also available. --toc is, for example, equivalent to --navigation=toc:
% epubinfo --toc ./linear-algebra.epub
