QDEL(1P)                  POSIX Programmer's Manual                 QDEL(1P)

PROLOG         top

       This manual page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior), or
       the interface may not be implemented on Linux.

NAME         top

       qdel — delete batch jobs

SYNOPSIS         top

       qdel job_identifier...

DESCRIPTION         top

       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         top

       None.

OPERANDS         top

       The qdel utility shall accept one or more operands that conform to
       the syntax for a batch job_identifier (see Section 3.3.1, Batch Job
       Identifier).

STDIN         top

       Not used.

INPUT FILES         top

       None.

ENVIRONMENT VARIABLES         top

       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 POSIX.1‐2008, Section 8.2, Internationalization
                 Variables 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         top

       Default.

STDOUT         top

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

STDERR         top

       The standard error shall be used only for diagnostic messages.

OUTPUT FILES         top

       None.

EXTENDED DESCRIPTION         top

       None.

EXIT STATUS         top

       The following exit values shall be returned:

        0    Successful completion.

       >0    An error occurred.

CONSEQUENCES OF ERRORS         top

       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         top

       None.

EXAMPLES         top

       None.

RATIONALE         top

       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 deleting 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 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 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         top

       The qdel utility may be removed in a future version.
