# GitHub doesn't currently support deleting old workflows unless you delete
# all previous runs of it. This scripts will delete all the runs for a given
# workflow. Use with caution!!! It will prompt before deletion.
#
# Usage: delete-workflow.sh <org/repo> <workflow-name (aka path to workflow
# file e.g. blahblah.yml )>
#
# PREREQUISITES: Install https://github.com/cli/cli and authenticate with it.
