# Consul ACL Role Update
Command: `consul acl role update`
Corresponding HTTP API Endpoint: [\[PUT\] /v1/acl/role/:id](/api-docs/acl/roles#update-a-role)
The `acl role update` command is used to update a role. The default operations is to merge the
current role with those values provided to the command invocation. Therefore to
update just one field, only the `-id` or `-name` options and the option to
modify must be provided. Note that renaming roles requires both the `-id` and
`-name` as the new name cannot yet be used to lookup the role.
The table below shows this command's [required ACLs](/api-docs/api-structure#authentication). Configuration of
[blocking queries](/api-docs/features/blocking) and [agent caching](/api-docs/features/caching)
are not supported from commands, but may be from the corresponding HTTP endpoint.
