Un script shell qui permet d’optimiser la place prise par de nombreux fichiers. Le script va optimiser la taille des fichiers JPG et PNG sans perte de qualité. Ensuite, il fera une liste récursive des fichiers vidéo (.mp4, .mkv, .avi, .m4v, .wmv) et optimisera leur taille si le gain est supérieur à une valeur choisie (75% par défaut). Finalement, il optimisera la taille des fichiers PDF qui, seuls, ne sont pas très lourds, mais peuvent prendre beaucoup de place s’ils sont multiples.
Pour lancer le script, ne pas oublier d'autoriser l'exécution : chmod +x ./FilesOptim.sh
Puis exécuter le script : ./FilesOptim.sh
Et voilà, après tout se fait tout seul !
A shell script that optimizes the size of many files. The script will optimise the size of JPG and PNG files without loss of quality. Next, it will recursively list video files (.mp4, .mkv, .avi, .m4v, .wmv) and optimise their size if the gain is greater than a chosen value (75% by default). Finally, it will optimise the size of PDF files which, on their own, are not very heavy, but can take up a lot of space if there are multiple files.
To launch the script, don't forget to authorise execution: chmod +x ./FilesOptim.sh
Then execute the script: ./FilesOptim.sh.
And that's it, afterwards everything is done by itself!
