Ctrl+C in a command line environment

While in a command line such as MS-DOS, Linux, and Unix, Ctrl+C is used to send a SIGINT signal, which cancels or terminates the currently running program. For example, if a script or program is frozen or stuck in an infinite loop pressing Ctrl+C will cancel that command and return you to the command line.
