.SH "DESCRIPTION"
|

.PP
|

\fBmysql_zap\fR
|

kills processes that match a pattern\&. It uses the
|
||||
\fBps\fR
|
||||
command and Unix signals, so it runs on Unix and Unix\-like systems\&.
|
||||
.PP
|
||||
Invoke
|
||||
\fBmysql_zap\fR
|
||||
like this:
|
||||
.sp
|

.if n \{\

|
||||
.\}
|
||||
.PP
|
||||
A process matches if its output line from the
|
||||
\fBps\fR
|
||||
command contains the pattern\&. By default,
|
||||
\fBmysql_zap\fR
|
||||
asks for confirmation for each process\&. Respond
|
||||
y
|
||||
to kill the process, or
|
||||
q
|
||||
to exit
|
||||
\fBmysql_zap\fR\&. For any other response,
|
||||
\fBmysql_zap\fR
|
||||
does not attempt to kill the process\&.
|
||||
.PP
|
||||
If the
|
||||
\fB\-\fR\fB\fIsignal\fR\fR
|
||||
option is given, it specifies the name or number of the signal to send to each process\&. Otherwise,
|
||||
\fBmysql_zap\fR
|
||||
tries first with
|
||||
TERM
|
||||
(signal 15) and then with
|
||||
KILL

(signal 9)\&.
