Please make sure you always remember that:
1. -o does always append to the file, it does not override it (to avoid users to lose important data)
2. hex sums is very vague it could be anything. Tell us what the algorithm is and...
3. use the -m switch when using --show, example: ./oclHashcat64.bin -m 0 --show -o outfile.txt hashes.txt
4. what happens when you don't use -o at all ?
