Usage: vault capabilities [options] [TOKEN] PATH
Fetches the capabilities of a token for a given path. If a TOKEN is provided
as an argument, the "/sys/capabilities" endpoint and permission is used. If
no TOKEN is provided, the "/sys/capabilities-self" endpoint and permission
is used with the locally authenticated token.
List capabilities for the local token on the "secret/foo" path:
$ vault capabilities secret/foo
List capabilities for a token on the "cubbyhole/foo" path:
$ vault capabilities 96ddf4bc-d217-f3ba-f9bd-017055595017 cubbyhole/foo
For a full list of examples, please see the documentation.
