A signal is a software interrupt, an asynchronous communication method that handles an asynchronous event. For example, we run the program in the terminal, by pressing the keyboard "CTRL + C", you can send a SIGINT interrupt signal to stop the

signal and its processing signal processing is an event that UNIX and Linux systems generate in response to certain conditions, usually the kernel generates a signal, and the process receives a signal and takes action accordingly .For example,

$ kill -l1) SIGHUP 2) SIGINT 3) SIGQUIT 4) SIGILL5) SIGTRAP 6) SIGABRT 7) SIGBUS 8) SIGFPE9) SIGKILL 10) SIGUSR1 11) SIGSEGV 12) SIGUSR213) SIGPIPE 14) SIGALRM 15) SIGTERM 16) SIGSTKFLT 17)

For a complete signal Life Cycle (after the signal is sent to the corresponding processing function for execution), it can be divided into three phases: Signal Generation Sign up in process Logout of signal in process Signal processing
