# stack es indices put-settings cli command
<cli-modifiers>
</cli-modifiers>

```bash
elastic stack es indices put-settings [options]
```

Update index settings.
**Behaviour flags:**
`--dry-run` — validate all inputs and exit without performing any action

## Options

<definitions>
  <definition term="--allow-no-indices">
    A setting that does two separate checks on the index expression.
    If `false`, the request returns an error (1) if any wildcard expression
    (including `_all` and `*`) resolves to zero matching indices or (2) if the
    complete set of resolved indices, aliases or data streams is empty after all
    expressions are evaluated. If `true`, index expressions that resolve to no
    indices are allowed and the request returns an empty result.
  </definition>
  <definition term="--expand-wildcards enum">
    Type of index that wildcard patterns can match. If the request can target
    data streams, this argument determines whether wildcard expressions match
    hidden data streams. Supports comma-separated values, such as
    `open,hidden`.
    **Values:** all, open, closed, hidden, none
    **Repeatable:** pass `--expand-wildcards` multiple times to supply more than one value
  </definition>
  <definition term="--flat-settings">
    If `true`, returns settings in flat format.
  </definition>
  <definition term="--ignore-unavailable">
    If `false`, the request returns an error if it targets a concrete (non-wildcarded)
    index, alias, or data stream that is missing, closed, or otherwise unavailable.
    If `true`, unavailable concrete targets are silently ignored.
  </definition>
  <definition term="--master-timeout string">
    Period to wait for a connection to the master node. If no response is
    received before the timeout expires, the request fails and returns an
    error.
  </definition>
  <definition term="--preserve-existing">
    If `true`, existing index settings remain unchanged.
  </definition>
  <definition term="--reopen">
    Whether to close and reopen the index to apply non-dynamic settings.
    If set to `true` the indices to which the settings are being applied
    will be closed temporarily and then reopened in order to apply the changes.
  </definition>
  <definition term="--timeout string">
    Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error.
  </definition>
  <definition term="--settings string">
  </definition>
  <definition term="--index string">
    Comma-separated list of data streams, indices, and aliases used to limit
    the request. Supports wildcards (`*`). To target all data streams and
    indices, omit this parameter or use `*` or `_all`.
    **Repeatable:** pass `--index` multiple times to supply more than one value
  </definition>
  <definition term="--error-trace">
    When set to `true` Elasticsearch will include the full stack trace of errors
    when they occur.
  </definition>
  <definition term="--filter-path string">
    Comma-separated list of filters in dot notation which reduce the response
    returned by Elasticsearch.
    **Repeatable:** pass `--filter-path` multiple times to supply more than one value
  </definition>
  <definition term="--human">
    When set to `true` will return statistics in a format suitable for humans.
    For example `"exists_time": "1h"` for humans and
    `"exists_time_in_millis": 3600000` for computers. When disabled the human
    readable values will be omitted. This makes sense for responses being consumed
    only by machines.
  </definition>
  <definition term="--pretty">
    If set to `true` the returned JSON will be "pretty-formatted". Only use
    this option for debugging only.
  </definition>
  <definition term="--input-file string">
    path to a JSON file to use as command input
  </definition>
  <definition term="--dry-run">
    validate all inputs and exit without performing any action (preview changes without applying them)
  </definition>
</definitions>
