How can I run a command on all files in a directory and mv to a different the ones that get an output that contains 'Cannot read TIFF header'?

Question

I'd like to remove all bad tiffs from out of a very large directory. The commandline tool "tiffinfo" makes it easy to identify them:

tiffinfo -D *

This will have an ouput like this:

00074000/74986.TIF: Cannot read TIFF header.

if the tiff file is corrupt. If this happens I'd like to take the file and move it to a different dirrectory: bad_images. I tried using awk on this, but it hasn't worked so far... Thanks!

Answer 1

Assuming the "Cannot read TIFF header" error comes on standard error, and assuming tiffinfo outputs other data on standard out which you don't want, then:

cd /path/to/tiffs
for file in `tiffinfo -D * 2>&1 >/dev/null | cut -f1 -d:`
do
    echo mv $file /path/to/bad_images
done

Remove the echo to actually move the files, once satisfied that the script will work as expected.
