7.14. mysql_zapKill Processes That Match a Pattern

mysql_zap kills processes that match a pattern. It uses the ps command and Unix signals, so it runs on Unix and Unix-like systems.

Invoke mysql_zap like this:

shell> mysql_zap [-signal] [-?Ift] pattern

A process matches if its output line from the ps command contains the pattern. By default, mysql_zap asks for confirmation for each process. Respond y to kill the process, or q to exit mysql_zap. For any other response, mysql_zap does not attempt to kill the process.

If the -signal option is given, it specifies the name or number of the signal to send to each process. Otherwise, mysql_zap TRies first with TERM (signal 15) and then with KILL (signal 9).

mysql_zap understands the following additional options:

• --help, -?, -I

  Display a help message and exit.

• -f

  Force mode. mysql_zap attempts to kill each process without confirmation.

• -t

  Test mode. Display information about each process but do not kill it.
