That's a dangerous use of backticks, useless use of ls *, and useless use of cat. You can't cram arbitrary sizes of things into backticks and shouldn't try. Either use pipes or temp files.

I can't quite understand what you want it to be doing from your malfunctioning program. Could you show what files it's supposed to be using, what files it's supposed to get out, and which files create what?

I'd start with:

Code:
# Find all files inside /raid/r04/wconnor/Sites/*_30km that aren't named '*.hdr', save to temp file.
# The temp file won't change later, so 'find' can't feed your own files created files back into your script.
find /raid/r04/wconnor/Sites/*_30km -type f '!' -name '*.hdr' > /tmp/$$

# Read lines from temp file
while read FILE
do
        ...
done < /tmp/$$

rm -f /tmp/$$

...but what you want done with the files isn't too clear.
