SYNTAX kill [-s sigspec] [-n signum] [-sigspec] jobspec or pid kill -l [exit_status] key -l : List the signal names -s : Send a specific signal -n : Send a specific signal number
Send 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
SIG prefix) or a signal number; signum is a signal
If sigspec and signum are not present,

If any arguments are supplied when `-l' 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.
