This seems the simplest way to make a spinner. To stop it, use the break (ctrl+c) 😉

#!/usr/bin/env bash

# Hide cursor
echo -en "\033[?25l"

# Spin spin spin...
i=1
sp='\|/-'
delay=0.15

while :
do
	printf "\b${sp:i++%${#sp}:1}"
	sleep $delay
done

#!/usr/bin/env bash

# Hide cursor

echo -en "\033[?25l"

# Spin spin spin...

i=1

sp='\|/-'

delay=0.15

while :

printf "\b${sp:i++%${#sp}:1}"

sleep $delay

done
