find_corrupt_jpegs.sh

Finds JPEG files that lack an End-Of-Image marker and are thus corrupt (for example due to a partial/failed download).
Such files often pass validation checks of other tools because they start with a valid file header.

Installation

wget "https://raw.githubusercontent.com/reformat0r/find_corrupt_jpegs/master/find_corrupt_jpegs.sh" && chmod +x find_corrupt_jpegs.sh

Usage

./find_corrupt_jpegs.sh outfile.txt my_photo_dir another_dir photos_*_2020

Example output

 ▇▇▇▇▇▇▇▇▇▇▇      |  70% - 1 broken

Output file

$ cat outfile.txt
my_photo_dir/foo.jpg
another_dir/bar.jpg
photos_03_2020/all_is_vibration.jpg
