.SH NAME
kill \- send a signal to a process
.SH SYNOPSIS
\fBkill\fR [ \-\fBsignal\fR | \-s \fBsignal\fR ] \fBpid\fR ...
.br
\fBkill\fR [ \-L | -V, \-\-version ]
.br
\fBkill\fR \-l [ \fBsignal\fR ]
.B kill
[options] <pid> [...]
.SH DESCRIPTION
The default signal for kill is TERM. Use \-l or \-L to list available signals.
Particularly useful signals include HUP, INT, KILL, STOP, CONT, and 0.
Alternate signals may be specified in three ways: \-9 \-SIGKILL \-KILL.
Negative PID values may be used to choose whole process groups; see the
PGID column in ps command output. A PID of \-1 is special; it indicates
all processes except the kill process itself and init.

.SH DESCRIPTION
These tools are probably obsolete and unportable. The command
syntax is poorly defined. Consider using the killall, pkill,
and pgrep commands instead.
The default signal for skill is TERM. Use \-l or \-L to list available signals.
Particularly useful signals include HUP, INT, KILL, STOP, CONT, and 0.
Alternate signals may be specified in three ways: \-9 \-SIGKILL \-KILL.
The default priority for snice is +4. (snice +4 ...)
Priority numbers range from +20 (slowest) to \-20 (fastest).
Negative priority numbers are restricted to administrative users.
.SH "GENERAL OPTIONS"
.TS
lB l l.
\-f fast mode This is not currently useful.
\-i interactive use You will be asked to approve each action.
\-v verbose output Display information about selected processes.
\-w warnings enabled This is not currently useful.
\-n no action This only displays the process ID.
\-V show version Displays version of program.
