Pour des images, télécharger le paquet jhead puis

for i in $(ls *.jpg); do 
	date=$(jhead $i | grep "File date"); 
	date=${date#*: }; 
	date=${date//:/}; 
	an=${date:0:4}; 
	mois=${date:4:2}; 
	dossier=$an"/"$mois; echo $i" -> "$dossier; 
	mkdir -p $dossier;
	mv "$i" $dossier; 
done;

Ou en une ligne :

for i in $(ls *.jpg); do date=$(jhead $i | grep "File date"); date=${date#*: }; date=${date//:/}; an=${date:0:4}; mois=${date:4:2}; dossier=$an"/"$mois; echo $i" -> "$dossier; mkdir -p $dossier; mv "$i" $dossier; done;

Pour des vidéos, installer libimage-exiftool-perl

for i in $(ls *.mp4); do 
	date=$(exiftool $i | grep Modification);
	date=${date#*: }; 
	date=${date//:/}; 
	date=${date%+*}; 
	an=${date:0:4}; 
	mois=${date:4:2}; 
	dossier=$an"/"$mois; echo $i" -> "$dossier; 
	mkdir -p $dossier;
done;

for i in $(ls *.mp4); do date=$(exiftool $i | grep Modification);date=${date#*: }; date=${date//:/}; date=${date%+*}; an=${date:0:4}; mois=${date:4:2}; dossier=$an"/"$mois; echo $i" -> "$dossier; mkdir -p $dossier; done;
