ctrl-z: (suspend foreground process )    send   SIGTSTP  signals to all processes in the foreground process group, often used to suspend a process, and FG/BG

FG command resumes execution of suspended in the foreground. can be used at this time. ctrl-z suspend the process again, BG command resumes execution of a suspended process in the background, which will not be available at this time ctrl-z again suspend the process;

ctrl-d: (Terminate input, or exit shell) A special binary value that represents EOF, which is equivalent to entering exit in the terminal to enter ;
