The command "hn --keep-open" is incomplete as it lacks context. It appears to be a command executed in a command-line interface or a script, but without knowing the specific program or tool it belongs to, it is challenging to provide accurate information about its purpose and functionality.

However, generally speaking, the "--keep-open" option in a command often implies that the program will continue running or keep a connection active without terminating or closing automatically. It suggests that the program or command is meant to maintain an open state for an extended period, waiting for further input or maintaining a continuous process.
