jhead
Image timestamp and EXIF data manipulation.
TLDR
Show all EXIF data
$ jhead [path/to/image.jpg]
Set the file's date and time to the EXIF create date (file creation date will be changed)
$ 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
$ jhead -n%Y_%m_%d-%H_%M_%S *.jpg
Rotate losslessly all JPEG images by 90, 180 or 270 based on the EXIF orientation tag
$ jhead -autorot *.jpg
Update all EXIF timestamps (Format: +- hour:minute:seconds) (example: forgot to change the camera's time zone - removing 1 hour from timestamps)
$ jhead -ta-1:00:00 *.jpg
Remove all EXIF data (including thumbnails)
$ jhead -purejpg [path/to/image.jpg]
