jhead -ft {{path/to/image.jpg}}

• Set the EXIF time to the file's date and time (EXIF data will be changed):

jhead -dsft {{path/to/image.jpg}}

• Rename all JPEG files based on the EXIF create date to YYYY_MM_DD-HH_MM_SS.jpg:

• Rotate losslessly all JPEG images by 90, 180 or 270 based on the EXIF orientation tag:
