default_args="-C - --retry 5"

usage="${script_name} force retries executing curl until it exits successfully.
Passed arguments are passed to curl. By default, we additionally pass these args:
${default_args}
To execute a curl program, you should include the URL and other options,
if necessary. Example:
${script_name} -L -O {URL}"

execute() {
   curl ${default_args} "$@"
}

if [ "$#" -lt 1 ]; then
    echo "${usage}" 1>&2
    exit 1
fi

while [ "${ret}" -eq 1 ];
do
    if [ "${count}" -eq 1 ]; then
        echo "Executing curl ${default_args}" "$@" 1>&2
    else
        echo "${count}: Trying again to execute curl" 1>&2
    fi
    if execute "$@"; then
       ret=0

    count=$((count + 1))
    echo "---------------"
    sleep 1
