pass argument to DAG, task apache airflow

I'm exploring apache airflow 1.8. I'm curious that either is there any way to pass arguments to DAGs or tasks while backfilling?

Here is something like that I'm searching for,

airflow backfill My_DAG -s some_date -e end_date argument_for_t1 argument_for_t2

or it could be array of args.

is there any way to pass arguments? I've searched a lot, but wasn't able to find anything.

I came across the solution that I can set the variables using airflow variables -s my_var="some value"

Now I can access my_var anywhere across the application.

for more options check cli

Backfill is to re-run a failed/missed/mis configured DAG and hence there is no provision to give command line arguments.

However, you can go to DagBag folder and give params to the dag object (Change/fix existing dag) and then back fill the DAG
