Description: The ‘halt’ command in Linux is used to stop the operating system in a controlled manner. The ‘-k’ option is a variant that sends a stop signal to running processes without shutting down the system. By using ‘halt -k’, the system does not power down, but a signal is sent to processes to stop, which can be useful in situations where resources need to be freed or specific tasks need to be halted without completely interrupting the system’s operation. This functionality is especially relevant in environments where a high degree of availability and control over running processes is required. The ‘-k’ option indicates that the stop is just a signal and not a complete shutdown, allowing system administrators to manage system processes and resources more effectively.
