Stop a process from running, either via a signal or forced termination.
kill [-s sigspec] [-n signum] [-sigspec] jobspec or pid
kill -l [exit_status]
-l : List the signal names
-s : Send a specific signal
-n : Send a specific signal numberSend a signal specified by sigspec or signum to the process named by job specification jobspec or process ID pid.
sigspec is either a signal name such as SIGINT (with or without the SIG prefix) or a signal number; signum is a signal number.
If sigspec and signum are not present, SIGTERM is used (Terminate).
If any arguments are supplied when &qt;-l&qt;&qt; is given, the names of the signals corresponding to the arguments are listed, and the return status is zero. exit_status is a number specifying a signal number or the exit status of a process terminated by a signal.
The return status is zero if at least one signal was successfully sent, or non-zero if an error occurs or an invalid option is encountered.
