Stop a process from running, either via a signal or forced termination.
Syntax kill [-s sigspec] [-n signum] [-sigspec] jobspec or pid kill -l [exit_status] kill -l [sigspec] 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 case-insensitive signal name such as
SIGINT (with or without the
SIG prefix) or a signal number; signum is a signal number.
If sigspec is not present,
SIGTERM is used (Terminate).
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 true if at least one signal was successfully sent, or false if an error occurs or an invalid option is encountered.
