Addon.d bash script for removing apks after nightly reflash on Android 5.1 CM12.1 not working

Tout ceci s'est fait par tâtonnement et par copie de scripts, je n'ai qu'une vague connaissance de bash et je n'ai absolument aucune idée de ce que je risque. Tout est fait avec des sauvegardes et des reflashes prudents.

#!/sbin/sh
# 
# /system/addon.d/77-MyApps.sh
#
# During a dirty flash, this script will backup files and apps at /system/*
# /system is formatted and reinstalled, then the files are restored.

J'ai bricolé ce script pour sauvegarder le mien (après de nombreux reflashes et restaurations) et supprimer certaines alternatives AOSP. Il semble que vous deviez écrire le code qui doit être exécuté après le flashage ici ( webview provient de l'ancienne AOSP, tandis que Webview est un désordre plus rationalisé). Le modèle est tiré de XDA en ce qui concerne grinder777. Si cela fonctionne, offrez-vous une tablette de chocolat et envoyez-lui (à elle ?) un remerciement. Si ça ne marche pas, je n'ai aucune idée de ce qui marchera, à part ce qu'a dit @Android Dev, mais ce n'est pas définitif.

EDIT : Comme YouKnowNothingJohn l'a dit, vous avez besoin d'au moins un commande de sauvegarde. Cette commande peut être n'importe quoi, même un fichier fictif (au moins dans >4.4). Merci M. Snow.
