What's the exit status code?

Have you verified that the path is correct? Is it a full path or a
relative path (in this case it may not be relative to the script
executed first)?


If your script takes all the files in the directory, but always missing
one file, then your outer loop has issues, as you haven't provided how
you get your $data in the first place, it's just a guessing game for us
who ain't mind readers.
