Set or update a permission on an account.
The [authority] field can be either a *public key* or a path to a YAML
If you specify a public key, a simple 'authority' structure is built,
with a threshold of 1, and a single key.
Otherwise, it should be a path to a YAML file. Here is a sample YAML
- key: EOS6MRyAjQq8ud7hVNYcfn................tHuGYqET5GDW5CV
- wait_sec: 300
eosc system updateauth [account] [permission_name] [parent permission or ""] [authority] [flags]
