.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
|
||||
.BR 6
|
||||
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 ps (1),
|
||||
.BR kill (2),
|
||||
.BR signal (2)
|
||||
.SH STANDARDS
|
||||
The
|
||||
.BR kill
|
||||
function is expected to be
|
||||
POSIX-2
|
||||
compatible.
|
||||
.SH VERSION
|
||||
This manual page documents
|
||||
.BR kill
|
||||
version 1.0.
|
||||
.SH ATTRIBUTIONS
|
||||
This command was ported from FreeBSD source code
|
||||
for distribution with GNO/ME 2.0.6.
