kill - send signals to processes, or list signals


kill [-s SIGNAL | -SIGNAL] PID... kill -l [SIGNAL]... kill -t [SIGNAL]...


Send signals to processes, or list signals.

Mandatory arguments to long options are mandatory for short options too.
-s, --signal=SIGNAL, -SIGNAL
specify the name or number of the signal to be sent
-l, --list list signal names, or convert signal names to/from numbers
-t, --table
 print a table of signal information
--help display this help and exit
 output version information and exit
SIGNAL may be a signal name like ‘HUP’, or a signal number like ‘1’, or the exit status of a process terminated by a signal. PID is an integer; if negative it identifies a process group.

NOTE: your shell may have its own version of kill, which usually supersedes the version described here. Please refer to your shell’s documentation for details about the options it supports.
