http-server:tldr:586d4
This command is using the "http-server" tool to start a web server with authentication. The "--username" and "--password" flags are used to specify the username and password required for authentication.
The "${username}" and "${password}" are placeholders for variables where you should provide the actual values. These variables can be replaced with your desired username and password.
For example, if you want to start the server with the username "admin" and the password "12345", you would replace "${username}" with "admin" and "${password}" with "12345" in the command.
Once the server is started with this command, anyone accessing it will be prompted to enter the specified username and password in order to access the resources served by the server.
