z/OS V1R9.0 UNIX System Services Command ... - Christian Grothoff

Description
Options
kill ends a process by sending it a signal. The default signal is SIGTERM.
kill in the tcsh shell
In the tcsh shell, kill [-signal] %job|pid ... sends the specified signal (or if none is
given, the TERM (terminate) signal) to the specified jobs or processes. job may be
a number, a string, ’’, %, + or - . Signals are either given by number or by name.
When using the tcsh kill command, do not use the first three characters (SIG) of
the signal_name. Enter the signal_name with uppercase characters. For example, if
you want to send the SIGTERM signal, you would enter kill -TERM pid not kill
-SIGTERM pid.
There is no default job. Specifying kill alone does not send a signal to the current
job. If the signal being sent is TERM or HUP (hangup), then the job or process is
sent a CONT (continue) signal as well.
kill -l lists the signal names. See “tcsh — Invoke a C shell” on page 626.
The signal_numbers and signal_names described in “Options” are also used with
the tcsh kill command.
–K Sends a superkill signal to force the ending of a process or job that did not
end as a result of a prior KILL signal. The process is ended with a
non-retryable abend. The regular KILL signal must have been sent at least
3 seconds before the superkill signal is sent. The superkill signal cannot be
sent to a process group (by using pid of 0 or a negative number) or to all
processes (by using a pid of -1).
–l Displays the names of all supported signals. If you specify exit_status, and
it is the exit code of a ended process, kill displays the ending signal of that
process.
–s signal_name
Sends the signal signal_name to the process instead of the SIGTERM
signal. When using the kill command, do not use the first three characters
(SIG) of the signal_name. Enter the signal_name with uppercase
characters. For example, if you want to send the SIGABRT signal, enter:
kill –s ABRT pid
–signal_name
(Obsolete.) Same as –s signal_name.
–signal_number
(Obsolete.) A non-negative integer representing the signal to be sent to the
process, instead of SIGTERM.
The signal_number represents the signal_name shown below:
signal_number
signal_name
0 SIGNULL
1 SIGHUP
2 SIGINT
3 SIGQUIT
4 SIGILL
5 SIGPOLL
6 SIGABRT
kill
