See if Ponibooru image files have the MD5 hashes that they should have:

$ cd /z9/t/pony/web_raws/Ponibooru-All-Safe; find . -type f | xargs -d "\n" sh -c 'for args do echo ==== $args ====; sqlite3 -column -header -csv -cmd "select * from images where md5sum=\"$(md5sum "$args" | sed "s/ .*//g")\";foobar" -bail /path/to/meta.sqlite 2>/dev/null; done' _ > ../check.txt # or "cat files.txt | tr -s "\n" "\n" | xargs..."

For those that don't run vim on check.txt:

:%s/^==== \(.*\) ====$\n====/XfMG8e5FwZPufiG3tbkJy \1\r/g
:g!/XfMG8e5FwZPufiG3tbkJy/d

In HTTP, you may see this bad empty file:
