List all values of signame supported by the implementation. No signals are sent with this option. The symbolic names of the signals (without the SIG pre®x) are written to standard output, separated by spaces and newlines.

NAME

kill - send a signal to a process; terminate a process

SYNOPSIS

kill [-ssigname] pid ...

kill [-ssignum] pid ...

kill -l

Obsolescent Versions:

kill -signame pid ...

kill -signum pid ...

DESCRIPTION

The kill command sends a signal to each process speci®ed by a pid process identi®er. The default signal is SIGTERM, which normally terminates processes that do not trap or ignore the signal.

pid is a process identi®er, an unsigned or negative integer that can be one of the following:

> 0 The number of a process.

=0 All processes, except special system processes, whose process group ID is equal to the process group ID of the sender.

=-1All processes, except special system processes, if the user has appropriate privileges. Otherwise, all processes, except special system processes, whose real or effective user ID is the same as the user ID of the sending process.

<-1All processes, except special system processes, whose process group ID is equal to the absolute value of pid and whose real or effective user ID is the same as the user of the sending process.

Process numbers can be found with the ps command (see ps(1)) and with the built-in jobs command available in some shells.

Options

kill recognizes the following options: -l(ell)

-ssigname

Send the speci®ed signal name. The default is SIGTERM, number 15. signame

 

can be speci®ed in upper- and/or lowercase, with or without the SIG pre®x. These

 

values can be obtained by using the -loption. The symbolic name SIGNULL

 

represents signal value zero. See "Signal Names and Numbers" below.

-ssignum

Send the speci®ed decimal signal number. The default is 15, SIGTERM. See "Sig-

 

nal Names and Numbers" below.

-signame

(Obsolescent.) Equivalent to -ssigname.

-signum

(Obsolescent.) Equivalent to -ssignum.
