[bash] mon script pour optimiser la taille des fichiers

[supprimé]

Bonjour,

un script de ma réalisation, qui permet d'optimiser la taille des fichiers avec différentes opérations selon le type avec de nombreux programmes inclus ou non dans la distribution.

Ce que le script fait :

optimise la compression des archives (zip, rar, ...) et choisi une compression supérieur quand nécessaire (zip --> 7zip, ...)
optimise la compression des images (gif, png, jpg, ...)
converti les données non compressées sans perte (wav --> flac, bmp --> png, xcf --> xcf.gz, svg --> svgz, ...)
optimise le code de différents fichiers (css, php, html, ...)
efface les fichiers inutiles (temporaire, vide, ...)

Comment :

exécute uniquement si le ou les programmes existe (passe au fichier suivant si un programme n'existe pas)
conserve date de fichier original
récursivité (décompresse le contenu des archives pour une taille optimale du fichier finale, pas de conversion de format de fichier à l'intérieur d'une archive)
journalisation (~/opti.csv)
et 100% sans perte de données

Fonctionnement :

opti.sh fichier
opti.sh dossier (. pour dossier actuel)

pour l'instant le script utilise que le premier argument et ne fonctionne que avec un argument

!! a utiliser bien sur qu'a vos risque et périls, aucune garantie de fonctionnement, faites des sauvegardes et vérifier vos fichiers !!

moi personnellement je trouve mon script génial et je m'en sert très régulièrement 🙂 en espérant que ça servent à quelqu'un. (et si quelqu'un connait un équivalent je suis aussi intéressé)

Mon dieu, quel travaille de géni!!

Bonjour,

j'ai un peu retravaillé mon script. Pratique avant d'envoyer un fichier sur un cloud ou par mail.

je vais donner des exemples (fichiers pris au hasard sur internet) :
