.SH DESCRIPTION
|
||||||
|
The
|
||||||
|
.BR kill
|
||||||
|
utility sends a signal to the processes specified by the
|
||||||
|
.IR pid
|
||||||
|
operand(s).
|
||||||
|
.PP
|
||||||
|
The options are as follows:
|
||||||
|
.IP \fB-s\fR \fIsignal_name\fR
|
||||||
|
A symbolic signal name specifying the signal to be sent instead of the
|
||||||
|
default
|
||||||
|
.BR TERM .
|
||||||
|
.IP \fB-l\fR [\fIexit_status\fR]
|
||||||
|
If no operand is given, list the signal names; otherwise, write
|
||||||
|
the signal name corresponding to
|
||||||
|
.IR exit_status .
|
||||||
|
.IP \fB-\fIsignal_name\fR
|
||||||
|
A symbolic signal name specifying the signal to be sent instead of the
|
||||||
|
default
|
||||||
|
.BR TERM .
|
||||||
|
.IP \fB-\fIsignal_number\fR
|
||||||
|
A non-negative decimal integer, specifying the signal to be sent instead
|
||||||
|
of the default
|
||||||
|
.BR TERM .
|
||||||
|
.PP
|
||||||
|
See the
|
||||||
|
.BR kill (2)
|
||||||
|
man page for information on
|
||||||
|
.IR pid s
|
||||||
|
that have special meanings.
|
||||||
|
.PP
|
||||||
|
Some of the more commonly used signals:
|
||||||
|
.RS
|
||||||
|
.BR 1
|
||||||
|
HUP (hang up)
|
||||||
|
.br
|
||||||
|
.BR 2
|
||||||
|
INT (interrupt)
|
||||||
|
.br
|
||||||
|
.BR 3
|
||||||
|
QUIT (quit)
|
||||||
|
.br
|
||||||
|

||||||
|
ABRT (abort)
|
||||||
|
.br
|
||||||
|
.BR 9
|
||||||
|
KILL (non-catchable, non-ignorable kill)
|
||||||
|
.br
|
||||||
|
.BR 14
|
||||||
|
ALRM (alarm clock)
|
||||||
|
.br
|
||||||
|
.BR 15
|
||||||
|
TERM (software termination signal)
|
||||||
|
.br
|
||||||
|
.BR 30
|
||||||
|
USR1 (user defined signal 1)
|
||||||
|
.br
|
||||||
|
.BR 31
|
||||||
|
USR2 (user defined signal 2)
|
||||||
|
.RE
|
||||||
|
.PP
|
||||||
|
.BR kill
|
||||||
|
is a built-in to
|
||||||
|
.BR gsh (1);
|
||||||
|
it allows job specifiers of the form ``%...'' as arguments
|
||||||
|
so process id's are not as often used as
|
||||||
|
.BR kill
|
||||||
|
arguments.

||||||
|
.SH SEE ALSO
|
||||||
|
.BR gsh (1),

.BR signal (2)
|
||||||
|
.SH STANDARDS
|
||||||

The
|
||||||
|
.BR kill
|
||||||
|
function is expected to be

||||||
|
compatible.
