How to break out of a program in an infinite loop?

You could send a SIGHUP (Ctrl-Z) or SIGTERM (Ctrl-C). The former merely pauses the program, you may resume with fg (or resume as a background process, using bg).

Either Ctrl-C as mentioned, or if that should not work, open another terminal, find the process using ps -ef|grep , find the process ID (pid), and use the kill command: kill -9

As mentioned, you can simply add a & to the command line. You can also hit CTRL-Z (this puts the process in the Stopped state), and then type bg to get it running in the background again...
