The screenshot tells that the process vsftpd_v1 vsftpd_v1.conf is running on the foreground. If a process is running on the foreground, that’s how the terminal looks as it tells that the terminal is currently running this process. This tells you that the server is running. Search on google about what is a foreground process and what is a background process.
