# Consul ACL Policy Update
Command: `consul acl policy update`
The `acl policy update` command is used to update a policy. The default operations is to merge the current policy
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
policies requires both the `-id` and `-name` as the new name cannot yet be used to lookup the
policy.
## Usage
Usage: `consul acl policy update [options] [args]`
#### API Options
<%= partial "docs/commands/http_api_options_client" %>
<%= partial "docs/commands/http_api_options_server" %>
#### Command Options
* `-description=<string>` - A description of the policy.
* `-id=<string>` - The ID of the policy to update. It may be specified as a
unique ID prefix but will error if the prefix matches multiple policy IDs
* `-meta` - Indicates that policy metadata such as the content hash and raft
indices should be shown for each entry
* `-name=<string>` - The policy's name.
* `-no-merge` - Do not merge the current policy information with what is provided
to the command. Instead overwrite all fields with the exception of
the policy ID which is immutable.
* `-rules=<string>` - The policy rules. May be prefixed with `@` to indicate that
the value is a file path to load the rules from. `-` may also be given to
indicate that the rules are available on stdin.
* `-valid-datacenter=<value>` - Datacenter that the policy should be valid within.
This flag may be specified multiple times.
