There is a command group 'az_appconfig_kv'. This group of commands could 'manage key values stored in an app configuration'. 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_kv_list'.The syntax is: az appconfig kv list [--all]
                     [--auth-mode {key, login}]
                     [--connection-string]
                     [--datetime]
                     [--endpoint]
                     [--fields {content_type, etag, key, label, last_modified, locked, tags, value}]
                     [--key]

                     [--snapshot]
                     [--top]. The 1th example of the child command would be to use it to 'list all key values with null label', the syntax is: az appconfig kv list -n MyAppConfiguration --label \0. The 2th example of the child command would be to use it to 'list a specific key for any label start with v1  using connection string', the syntax is: az appconfig kv list --key color --connection-string Endpoint=https://contoso.azconfig.io;Id=xxx;Secret=xxx --label v1.*. The 3th example of the child command would be to use it to 'list all keys with any labels and query only key  value and tags', the syntax is: az appconfig kv list --connection-string Endpoint=https://contoso.azconfig.io;Id=xxx;Secret=xxx --fields key value tags --datetime "2019-05-01T11:24:12Z". The 4th example of the child command would be to use it to 'list content of key vault reference with key prefix  kvref_  and only select key and value', the syntax is: az appconfig kv list -n MyAppConfiguration --key "KVRef_*" --resolve-keyvault --query "[*].{key:key, value:value}". The 5th example of the child command would be to use it to 'list key values with multiple labels', the syntax is: az appconfig kv list --label test,prod,\0 -n MyAppConfiguration. The 6th example of the child command would be to use it to 'list all key values with all labels using your  az login  credentials', the syntax is: az appconfig kv list --endpoint https://myappconfiguration.azconfig.io --auth-mode login. The 7th example of the child command would be to use it to 'list all key values in a given snapshot of the app configuration store', the syntax is: az appconfig kv list --connection-string Endpoint=https://contoso.azconfig.io;Id=xxx;Secret=xxx --snapshot MySnapshot. The parameter '--all' is optional. list all items.. 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 '--datetime' is optional. format: "yyyy-mm-ddthh:mm:ssz". if no time zone specified, use utc by default.. 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 '--fields' is optional. space-separated customized output fields.. The parameter '--key' is optional. if no key specified, return all keys by default. support star sign as filters, for instance abc* means keys with abc as prefix.. The parameter '--label' is optional. if no label specified, list all labels. support star sign as filters, for instance abc* means labels with abc as prefix. use '\0' for null label.. 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 '--resolve-keyvault' is optional. resolve the content of key vault reference. this argument should not be specified along with --fields. instead use --query for customized query.. The parameter '--snapshot' is optional. list all keys in a given snapshot of the app configuration store. if no snapshot is specified, the keys currently in the store are listed.. The parameter '--top -t' is optional. maximum number of items to return. must be a positive integer. default to 100..
