The exif command for Linux allows a user to get exif information from a camera image. This example below shows the sample output from this interesting utility. Very good to manage the exif data in your photos.

Since, this file contains a thumbnail, we can extract it like this.
┌─[user@parrot]─[~/Desktop] └──╼ $exif waterfall.jpg -e Wrote file 'waterfall.jpg.modified.jpeg'. |
And I can grep for the camera model like this.
localhost% exif lake-albert.jpg | grep Model Model |DMC-FT2 |
This is very useful when downloading a photo from the Internet and it could contain useful information.
