			==Sort two hash files and compare them==
			It's faster to create again another hashfile.txt from the second folder and then compare the two hashfiles.txt

			To compare the hashfiles.txt we need to sort them (unless they were created with the -j0 option), so for each of them:

			===Sort the hashfiles by the 4th field (filename)===
			sort -k 4 -t, hashdeep_$(date +%y%m%d).txt > hashdeep_$(date +%y%m%d).txt.sorted

			===List files only in the first folder===
			diff first.sorted second.sorted \|grep "<" \|cut -d, -f4 \|less

			===List files only in the second folder===
			diff first.sorted second.sorted \|grep ">" \|cut -d, -f4 \|less
