--- delete batch jobs
A batch job is deleted by sending a request to the batch server that
manages the batch job. A batch job that has been deleted is no longer
subject to management by batch services.
utility is a user-accessible client of batch services that requests the
deletion of one or more batch jobs.
utility shall request a batch server to delete those batch jobs for
which a batch
is presented to the utility.
utility shall delete batch jobs in the order in which their batch
are presented to the utility.
utility fails to process any batch
successfully, the utility shall proceed to process the remaining batch
utility shall delete each batch job by sending a
Delete Job Request
to the batch server that manages the batch job.
utility shall not exit until the batch job corresponding to each
successfully processed batch
has been deleted.
utility shall accept one or more operands that conform to the syntax
for a batch

unset or null. (See the Base Definitions volume of POSIX.1-2008,

the precedence of internationalization variables used to determine the
values of locale categories.)
If set to a non-empty string value, override the values of all the
other internationalization variables.
Determine the locale for the interpretation of sequences of bytes of
text data as characters (for example, single-byte as opposed to
multi-byte characters in arguments).
Determine the locale that should be used to affect the format and
contents of diagnostic messages written to standard error.
Determine the login name of the user.
An implementation of the
utility may write informative messages to standard output.
The standard error shall be used only for diagnostic messages.
The following exit values shall be returned:
An error occurred.
CONSEQUENCES OF ERRORS
In addition to the default behavior, the
utility shall not be required to write a diagnostic message to standard
error when the error reply received from a batch server indicates that
does not exist on the server. Whether or not the
utility waits to output the diagnostic message while attempting to
locate the job on other servers is implementation-defined.
The following sections are informative.
utility allows users and administrators to delete jobs.
utility provides functionality that is not otherwise available. For
utility of the operating system does not suffice. First, to use the
utility, the user might have to log in on a remote node, because the
utility does not operate across the network. Second, unlike
cannot remove jobs from queues. Lastly, the arguments of the
utility are job identifiers rather than process identifiers, and so
this utility can be passed the output of the
utility, thus providing users with a means of deleting a list of jobs.
Because a set of jobs can be selected using the
utility has not been complicated with options that provide for
selection of jobs. Instead, the batch jobs to be deleted are identified
individually by their job identifiers.
utility has been a component of NQS, the existing practice on which it
is based. However, the
utility defined in this volume of POSIX.1-2008 does not provide an option for specifying a
signal number to send to the batch job prior to the killing of the
process; that capability has been subsumed by the

possibility that the batch server may never respond, due to a down
router, down batch server, or other network mishap. The DESCRIPTION

In the broad sense, the network problem is also an error, which causes
the failure to process the batch job identifier.
