Thank you
Unless you had backups of your files before you destroyed some of them, they are gone. To avoid the problem in the future, change the script suggested by rdrtx1 to something more like:
Code:
#!/bin/bash

printf 'Enter starting number (0-9999): '
read n
if [ "$n" != "${n#*[^0-9]*}" || [ ${#n} -lt 1 ] || [ ${#n} -gt 4 ]
then	printf 'Starting number ("%s") is invalid\n' "$n" >&2
	exit 1
fi

# Move existing files into a different namespace...
for file in DSC_*.JPG
do	mv "$file" "old_$file"
done

# Now move them to the new locations in the original namespace.
for file in old_DSC_*.JPG
do	mv "$file" DSC_$(printf "%04d" $n).JPG
	n=$(($n+1))
done
