SIGQUIT 3 Core Quit from keyboard
SIGKILL 9 Term Kill signal
SIGQUIT 可以用ctrl+\ 发送给当前进程,退出时产生core dump。
SIGKILL被发送给一个程序时,它使程序立即终止。与SIGTERM和SIGINT相比,这个信号不能被捕获或忽略,同时接收这个信号的进程在收到这个信号时不能执行任何清理。
9是信号量,kill实际上是用来发送信号量给进程,你可以通过man kill查看信号量列表,这里给你一个我获得的信号量列表: Name Num Action Description 0 0 n/a exit code indicates if a signal may be sent ALRM 14 exit HUP 1 exit INT 2 exit KILL 9 exit cannot be blocked PIPE 13 exit POLL exit PROF exit TERM 15 exit USR1 exit USR2 exit VTALRM exit STKFLT exit might not be implemented PWR ignore might exit on some systems WINCH ignore CHLD ignore URG ignore TSTP stop might interact with the shell TTIN stop might interact with the shell TTOU stop might interact with the shell STOP stop cannot be blocked CONT restart continue if stopped, otherwise ignore ABRT 6 core FPE 8 core ILL 4 core QUIT 3 core SEGV 11 core TRAP 5 core SYS core might not be implemented EMT core might not be implemented BUS core core dump might fail XCPU core core dump might fail XFSZ core core dump might fail参考
