I keep trying to run this code but i keep getting the error "curl: option -: is unknown" HERE IS THE CODE

#!/bin/bash #crawl End Clothing for Product IDs for i in $(eval echo {$1..$2}) do rm -f end-cookie.jar curl -c end-cookie.jar - L -s -o /dev/null url=`curl -b end-cookie.jar -w "%{url_effective}\n" - L -s -S -o /dev/null echo $i - $url done

and when i run that i get the error

akshayk17j@ubuntu:~$ /home/akshayk17j/Desktop/TheEnd.sh curl: option -: is unknown curl: try 'curl --help' or 'curl --manual' for more information curl: option -: is unknown curl: try 'curl --help' or 'curl --manual' for more information {..} -
