ctrl-c,ctrl-z,ctrl-d Difference

Linux under: Ctrl-c sends SIGINT signals to all processes in the foreground process group. Often used to terminate a running program. Ctrl-z sends SIGTSTP signals to all processes in the foreground process group, often used to suspend a process. Instead of sending a signal, ctrl-d represents a special binary value that represents EOF. ctrl-/sends sigquit signals to all processes in the foreground process group, terminating the foreground process and generating core files.
