Anyone who want to simply rename his or her photo’s to a date format, will appreciate the ease of batch renaming them from the command-line.
jhead is the tool of choice for manipulation of images on the command-line using EXIF tags. There is a version available for all operating systems.
I like to rename my photos to the date-time the image was taken so I will use this command:
jhead -autorot -nf%y%m%d-%H%M%S *.jpg
But that is just the start of what this little program can do for you:
jhead can extract the following from an Exif jpeg file:
- Camera make and model
- Time and date picture was taken
- Integral low-res Exif thumbnail
- Shutter speed
- Camera F-stop number
- Flash used (yes/no)
- Distance camera was focused at
- Focal length and calculate 35 mm equivalent focal length
- Image resolution
- GPS info, if stored in image
- IPTC header
- XMP data
