Hi

This is a first working result made by a friend of mine which could be improved. Up to now, it processes only EPUB where the CSS file is in : OPS/style.css. It has to be adapted on this regard.

Spoiler:

#!/bin/bash
for fichier in *.epub
do
    unzip $fichier OPS/style.css
    if [ -d ./OPS ]; then
        cd OPS
        find . -type f -iname "style.css" -exec sed -i -e "s/vertical-align:top/vertical-align:text-top/g" {} \;
        cd ..
        zip -r $fichier ./OPS
        rm -rf ./OPS
    fi
done
