Pour un besoin récent, j’avais besoin de retrouver tout les epub que j’avais acheter chez un vendeur d’epub qui n’existe plus (feedbooks). Du coup, j’ai fait un script pour aller chercher dans ma bibliothèque.

#!/bin/bash

if [ $# -lt 2 ]
then
	echo
	echo "Usage: ${0} <path-to-epub-directory (aka calibre root biblio)> <name to search>"
	echo "export VERBOSE=1 to add verbosity or VERBOSE=1 ${0} ..."
	echo
	exit
fi

CUR_DIR=$(dirname "$0")
PATH_TO_SEARCH=$1
PATTERN_TO_SEARCH=$2

echo "Searching in ${PATH_TO_SEARCH} about ${PATTERN_TO_SEARCH}..."

mapfile FILES < <(find "$PATH_TO_SEARCH" -type f -name '*.epub')

N="${#FILES[@]}"

echo "... found ${N} epubs!"

for ((I=0; I<N; I++))
do
	epub_file=$(echo "${CUR_DIR}/${FILES[$I]}" | sed 's/\n//')
	fileloc=$(unzip -l "${epub_file}" | grep -o 'OEBPS/.*.xhtml')
	found=0
	for xhtml in $fileloc
	do
		metafound=$(zipgrep "${PATTERN_TO_SEARCH}" "${epub_file}" "${xhtml}")
		if [ "$metafound" != "" ]; then
			# display only once that we have found it
			if [[ "$found" -eq "0" ]]; then
				echo "Found in ${epub_file}"
			fi

			found=1
			if [[ "$VERBOSE" -eq "1" ]]; then
				printf "\t|_ %s\n" "$metafound"
			else
				break
			fi
		fi
	done
done

echo
echo 'EOL'
echo
exit

On ne sait jamais que cela vous serve
