Renaming pictures according EXIF data + rotating pictures

gistfile1.txt

- Renaming all *.JPG files according the EXIF date taken of the picture (it gives : 2014-11-24_13-13-42.jpg) : 

#jhead -n%Y-%m-%d_%H-%M-%S *.JPG

- Rotate all jpeg pictures of a directory :

#jhead -autorot *.jpg

- Rename & rotate recursively *.JPG files (and here, *.jpg also due to non sensitive search with the -iname option) starting from local directory :

#find . -iname "*.JPG" -exec jhead -n%Y-%m-%d_%H-%M-%S -autorot {} \; 

- Par exemple, pour enlever 1h15 à toutes les photos

#jhead -ta-1:15 *.jpeg

To retire 1h15 to the EXIF shot date/time of all .jpeg photos :
jhead -ta-1:15:00 *.jpeg

To add 1h15 to the EXIF shot date/time of all .jpeg photos :
jhead -ta+1:15:00 *.jpeg
