PROLOG

       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

       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 Section 3.3.1, 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  POSIX.1‐2017,  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

       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 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.1‐2017  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

       The qdel utility may be removed in a future version.
