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
       qrerun — rerun batch jobs


SYNOPSIS
       qrerun job_identifier...


DESCRIPTION
       To  rerun  a  batch  job  is  to terminate the session leader of the batch job, delete any
       associated checkpoint files, and return the batch job to the batch queued state.  A  batch
       job  is  rerun  by  a  request  to the batch server that manages the batch job. The qrerun
       utility is a user-accessible batch client that requests the rerunning of one or more batch
       jobs.

       The  qrerun  utility  shall  rerun  those  batch  jobs for which a batch job_identifier is
       presented to the utility.

       The  qrerun  utility  shall  rerun  batch  jobs  in  the  order  in  which   their   batch
       job_identifiers are presented to the utility.

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

       The qrerun utility shall rerun batch jobs by sending a Rerun  Job  Request  to  the  batch
       server that manages each batch job.

       For  each successfully processed batch job_identifier, the qrerun utility shall have rerun
       the corresponding batch job at the time the utility exits.


OPTIONS
       None.


OPERANDS
       The qrerun 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 qrerun:

       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
       None.


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 qrerun 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
       qrerun  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 qrerun utility allows users to cause jobs in the running state to exit and rerun.

       The qrerun utility is a new utility, vis-a-vis existing practice, that has been defined in
       this  volume  of  POSIX.1‐2017  to  correct  user-perceived  deficiencies  in the existing
       practice.


FUTURE DIRECTIONS
       The qrerun utility may be removed in a future version.
