Answer 1

In the following curl you will see two working variables:

1. $backup_hash without double quotes

2. $index with double quotes inside a JSON

curl -k -XPOST 'somesite/_snapshot/cs-automated/'"$backup_hash"'/_restore' -d '{"indices": "'"$index"'"}' -H 'Content-Type: application/json'

Use an editor with syntax highlight to ensure your code is not broken:
