The command "httpflow ${host httpbin-org or host baidu-com}" seems to be using a tool or script called "httpflow" to monitor HTTP traffic activity.
The "${host httpbin-org or host baidu-com}" part of the command is likely a parameter or options section that allows for specifying one or more hosts to monitor. In this case, it seems to be indicating that you can choose between monitoring traffic for either the "httpbin.org" or "baidu.com" hosts.
By running this command, the "httpflow" tool will likely capture network traffic related to HTTP requests and responses between your machine and the specified hosts. It may display information such as the request headers, response codes, URL paths, and other details about the HTTP transactions occurring between your machine and the chosen hosts.
