Are there any good Ubuntu/Debian/Linux-based tools for identifying corrupted jpeg images in a collection of tens of thousands? I know that there are a few in there, but I can't bring myself to view them all manually, even at the thumbnail level.

It might not be perfect, but you could use feh -p and examine the error messages generated.

To list all the unloadable images in /opt/images and below

feh -ur /opt/images

-u, --unloadable Don't display images. Just print out their names if imlib2 can NOT successfully load them. Returns false if at least one image was loadable.

-r, --recursive Recursively expand any directories in the commandline arguments to the content of those directories, all the way down to the bottom level.

  • From info feh ... feh --unloadables -r /opt/images Weed out (list) all the unloadable images in /opt/images and below.

    Actually, it's feh --unloadable -r /opt/images or feh -ur /opt/images. Apr 2 '11 at 22:50
  • Missed a description, or a link: man.finalrewind.org/1/feh "feh is an X11 image viewer aimed mostly at console users".
