How do I find files that do not end with a newline/linefeed?

Question

How can I list normal text (.txt) filenames, that don\'t end with a newline?

e.g.: list (output) this filename:

$ cat a.txt
asdfasdlsad4rand

Give this a try:

find . -type f -exec sh -c '[ -z "$(sed -n "\$p" "$1")" ]' _ {} \; -print

It will print filenames of files that end with a blank line. To print files that don't end in a blank line change the -z to -n.
