Name
kill — terminate a process
Synopsis
kill [ −s signal | −p ] [−a] [−−] pid...
DESCRIPTION
The command kill sends the specified signal to
the specified process or process group. If no signal is
specified, the TERM signal is sent. The TERM signal will kill
processes which do not catch this signal. For other
processes, it may be necessary to use the KILL (9) signal,
since this signal cannot be caught.
Most modern shells have a builtin kill function, with a
usage rather similar to that of the command described here.
The `-a' and `-p' options, and the possibility to specify
pids by command name is a local extension.
OPTIONS
pid...-
Specify the list of processes that
kill
should signal. Each pid can be one of five
things:
n-
where n is larger
than 0. The process with pid n will be
signaled.
0-
All processes in the current process group
are signaled.
- -1
-
All processes with pid larger than 1 will
be signaled.
−n-
where n is larger
than 1. All processes in process group
n
are signaled. When an argument of the form
`-n' is given, and it is meant to denote a
process group, either the signal must be
specified first, or the argument must be
preceded by a `--' option, otherwise it will
be taken as the signal to send.
commandname-
All processes invoked using that name will
be signaled.
−s
signal-
Specify the signal to send. The signal may be given
as a signal name or number.
−l-
Print a list of signal names. These are found in
/usr/include/linux/signal.h
−a-
Do not restrict the commandname-to-pid conversion to
processes with the same uid as the present process.
−p-
Specify that kill should only print the
process id (pid) of the named processes, and not send
any signals.
