                                         [--filter]
                                         [--max-items]
                                         [--next-token]
                                         [--top]. The 1th example of the child command would be to use it to 'list client group', the syntax is: az eventgrid namespace client-group list -g rg --namespace-name name. The parameter '--namespace-name' is required. It is used to name of the namespace.. The parameter '--resource-group -g' is required. It is used to name of resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--filter' is optional. the query used to filter the search results using odata syntax. filtering is permitted on the 'name' property only and with limited number of odata operations. these operations are: the 'contains' function as well as the following logical operations: not, and, or, eq (for equal), and ne (for not equal). no arithmetic operations are supported. the following is a valid filter example: $filter=contains(name, 'pattern') and name ne 'pattern-1'. the following is not a valid filter example: $filter=location eq 'westus'.. The parameter '--max-items' is optional. total number of items to return in the command's output. if the total number of items available is more than the value specified, a token is provided in the command's output. to resume pagination, provide the token value in `--next-token` argument of a subsequent command.. The parameter '--next-token' is optional. token to specify where to start paginating. this is the token value from a previously truncated response.. The parameter '--top' is optional. the number of results to return per page for the list operation. valid range for top parameter is 1 to 100. if not specified, the default number of results to be returned is 20 items per page..
