NAME

       qdel - delete batch jobs

SYNOPSIS

       qdel job_identifier ...

DESCRIPTION

       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.

       The qdel utility is a user-accessible client of batch services that requests the deletion of one or more batch jobs.

       The qdel utility shall request a batch server to delete those batch jobs for which a batch job_identifier is presented to the utility.

       The qdel utility shall delete batch jobs in the order in which their batch job_identifiers are presented to the utility.

       If the qdel utility fails to process any batch job_identifier successfully, the utility	shall  proceed	to  process  the  remaining  batch
       job_identifiers, if any.

       The qdel utility shall delete each batch job by sending a Delete Job Request to the batch server that manages the batch job.

       The qdel utility shall not exit until the batch job corresponding to each successfully processed batch job_identifier has been deleted.

OPTIONS

       None.

OPERANDS

       The qdel utility shall accept one or more operands that conform to the syntax for a batch job_identifier (see Batch Job Identifier ).

STDIN

       Not used.

INPUT FILES

       None.

ENVIRONMENT VARIABLES

       The following environment variables shall affect the execution of qdel:

       LANG   Provide  a  default  value  for  the  internationalization  variables  that  are	unset or null. (See the Base Definitions volume of
	      IEEE Std 1003.1-2001, Section 8.2, Internationalization Variables for the  precedence  of  internationalization  variables  used	to
	      determine the values of locale categories.)

       LC_ALL If set to a non-empty string value, override the values of all the other internationalization variables.

       LC_CTYPE
	      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).

       LC_MESSAGES
	      Determine the locale that should be used to affect the format and contents of diagnostic messages written to standard error.

       LOGNAME
	      Determine the login name of the user.

ASYNCHRONOUS EVENTS

       Default.

STDOUT

       An implementation of the qdel utility may write informative messages to standard output.

STDERR

       The standard error shall be used only for diagnostic messages.

OUTPUT FILES

       None.

EXTENDED DESCRIPTION

       None.

EXIT STATUS

       The following exit values shall be returned:

	0     Successful completion.

       >0     An error occurred.

CONSEQUENCES OF ERRORS

       In addition to the default behavior, the qdel utility shall not be required to write a diagnostic message to standard error when the  error
       reply  received	from  a batch server indicates that the batch job_identifier does not exist on the server. Whether or not the qdel utility
       waits to output the diagnostic message while attempting to locate the job on other servers is implementation-defined.

       The following sections are informative.

APPLICATION USAGE

       None.

EXAMPLES

       None.

RATIONALE

       The qdel utility allows users and administrators to delete jobs.

       The qdel utility provides functionality that is not otherwise available. For example, the kill utility of the  operating  system  does  not
       suffice.  First,  to use the kill utility, the user might have to log in on a remote node, because the kill utility does not operate across
       the network. Second, unlike qdel, kill cannot remove jobs from queues. Lastly, the arguments of the qdel utility are job identifiers rather
       than  process identifiers, and so this utility can be passed the output of the qselect utility, thus providing users with a means of delet-
       ing a list of jobs.

       Because a set of jobs can be selected using the qselect utility, the qdel 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.

       Historically,  the  qdel utility has been a component of NQS, the existing practice on which it is based. However, the qdel utility defined
       in this volume of IEEE Std 1003.1-2001 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 qsig utility.

       A  discussion  was  held  about the delays of networking and the possibility that the batch server may never respond, due to a down router,
       down batch server, or other network mishap. The DESCRIPTION records this under the words "fails to process  any	job  identifier".  In  the
       broad sense, the network problem is also an error, which causes the failure to process the batch job identifier.

FUTURE DIRECTIONS

       None.
