I didn't know that EPUB is based on HTML. I always had the impression that it has its own binary format. Using HTML as a base has a lot of sense.

- arp242 3y agoIt's just a zip file with HTML documents and some (ePub-specific) XML files to define metadata, chapters, and a few things like that. I use this "epub-edit" script to edit them: #!/bin/zsh # # Extract epub file to a temp directory, launch shell to edit it, and re-zip # it. Nothing about this is really epub-specific as such. echo " $@" | grep -q -- ' -h' && { sed '1,2d; /^[^#]/q; s/^# \?//;' "$0" | sed '$d'; exit 0; } # Show docs [ "${ZSH_VERSION:-}" = "" ] && echo >&2 "Only works with zsh" && exit 1 setopt err_exit no_unset no_clobber pipefail full=$1:a tmp=$(mktemp -d) bsdtar xf $1 -C $tmp cd $tmp print "Editing $1; press ^D to exit" zsh ||: mv -f $full $full.orig zip -f $full * cd - rm -r $tmp And then I use vim to edit the HTML files and such.
