.Nd terminate or signal a process
.Sh SYNOPSIS
.Nm kill
.Op Fl signal_name
.Ar pid
\&...
.Nm kill
.Op Fl signal_number
.Ar pid
\&...
.Nm kill
.Op Fl l
.Sh DESCRIPTION
The kill utility sends the
.Dv TERM
signal to the processes specified
by the pid operand(s).
.Pp
Only the super-user may send signals to other users' processes.
.Pp
The options are as follows:
.Pp
.Bl -tag -width Ds
.It Fl l
List the signal names.
.It Fl signal_name
A symbolic signal name specifying the signal to be sent instead of the
default
.Dv TERM .
The
.Fl l
option displays the signal names.
.It Fl signal_number
A non-negative decimal integer, specifying the signal to be sent instead
of the default
.Dv TERM .
.El
.Pp
Some of the more commonly used signals:
.Bd -ragged -offset indent -compact
.Bl -column XXX TERM
.It -1	-1	(broadcast to all processes, super-user only)
.It 0	0	(sh(1) only, signals all members of process group)
.It 2	INT	(interupt)
.It 3	QUIT	(quit)
.It 6	ABRT	(abort)
.It 9	KILL	(non-catchable, non-ignorable kill)
.It 14	ALRM	(alarm clock)
.It 15	TERM	(software termination signal)
.El
.Ed
.Pp
.Nm Kill
is a built-in to
.Xr csh  1  ;
it allows job specifiers of the form ``%...'' as arguments
so process id's are not as often used as
.Nm kill
arguments.
See
.Xr csh  1
for details.

for
.Xr csh  1
users should be provided.
