I'm trying to create a progress bar or some sort of loading icon to show that a hash is being created, instead of a blank screen with nothing happening... This is what I have so far:
if [[ $hashing != "y" && $hashing != "Y" ]]; then
echo -e "\n"
sudo dd if=dev/"$source" | md5sum
read -r compareresult
i=1
sp="/-\|"
echo -n ' '
while true
do
printf "\b${sp:i++%${#sp}:1}"
done
exit
fi ;;
This uses a spinning wheel to represent a loading icon. And it does work using what's above. But doesn't at the moment? Not sure if the order is incorrect or if I'm missing something. Any help would be great thanks
