# Consul ACL Role Update

Command: `consul acl role update`

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.

## Usage
