The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'. The group of commands has global parameter '--output -o' which means 'Output format.'. The group of commands has global parameter '--query' which means 'JMESPath query string. See <a href="http://jmespath.org/">http://jmespath.org/</a> for more information and examples.'. The group of commands has global parameter '--subscription' which means 'Name or ID of subscription. You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_appconfig_feature_filter_update'.The syntax is: az appconfig feature filter update --filter-name
                                   [--auth-mode {key, login}]
                                   [--connection-string]
                                   [--endpoint]
                                   [--feature]
                                   [--filter-parameters]
                                   [--index]
                                   [--key]

                                   [--yes]. The 1th example of the child command would be to use it to 'update the filter for feature  color  with label mylabel with name  myfilter  and 2 parameters', the syntax is: az appconfig feature filter update -n MyAppConfiguration --feature color --label MyLabel --filter-name MyFilter --filter-parameters Name=\"Value\" Name2=\"Value2\". The 2th example of the child command would be to use it to 'update the filter at index 2  zero based index  for feature  color  with label mylabel with name  myfilter  and 2 parameters', the syntax is: az appconfig feature filter update -n MyAppConfiguration --feature color --label MyLabel --filter-name MyFilter --filter-parameters Name=\"Value\" Name2=\"Value2\" --index 2. The 3th example of the child command would be to use it to 'update a filter for feature  color  with label mylabel and filter name  myfilter  with no parameters', the syntax is: az appconfig feature filter update -n MyAppConfiguration --feature color --label MyLabel --filter-name MyFilter. The 4th example of the child command would be to use it to 'update the filter for feature  color  with label mylabel with name  myfilter  and array parameters', the syntax is: az appconfig feature filter update -n MyAppConfiguration --feature color --label MyLabel --filter-name MyFilter --filter-parameters ArrayParam=[1,2,3]. The parameter '--filter-name' is required. It is used to name of the filter to be updated.. The parameter '--auth-mode' is optional. this parameter can be used for indicating how a data operation is to be authorized. if the auth mode is "key", provide connection string or store name and your account access keys will be retrieved for authorization. if the auth mode is "login", provide the store endpoint or store name and your "az login" credentials will be used for authorization. you can configure the default auth mode using `az configure --defaults appconfig_auth_mode=<auth_mode>`. for more information, see https://docs.microsoft.com/azure/azure-app-configuration/concept-enable-rbac.. The parameter '--connection-string' is optional. combination of access key and endpoint of app configuration. can be found using 'az appconfig credential list'. users can preset it using `az configure --defaults appconfig_connection_string=<connection_string>` or environment variable with the name azure_appconfig_connection_string.. The parameter '--endpoint' is optional. if auth mode is "login", provide endpoint url of the app configuration. the endpoint can be retrieved using "az appconfig show" command. you can configure the default endpoint using `az configure --defaults appconfig_endpoint=<endpoint>`.. The parameter '--feature' is optional. name of the feature whose filter you want to update. if the feature flag key is different from the default key, provide the `--key` argument instead.. The parameter '--filter-parameters' is optional. space-separated filter parameters in 'name[=value]' format. the value must be an escaped json string.. The parameter '--index' is optional. zero-based index of the filter to be updated in case there are multiple instances with same filter name.. The parameter '--key' is optional. key of the feature flag. key must start with the ".appconfig.featureflag/" prefix. key cannot contain the "%" character. if both key and feature arguments are provided, only key will be used. default key is the reserved prefix ".appconfig.featureflag/" + feature name.. The parameter '--label' is optional. if no label specified, update the feature flag with null label by default.. The parameter '--name -n' is optional. name of the app configuration. you can configure the default name using `az configure --defaults app_configuration_store=<name>`.. The parameter '--yes -y' is optional. do not prompt for confirmation..
