       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

       qrls — release batch jobs

SYNOPSIS         top

       qrls [−h hold_list] job_identifier...

DESCRIPTION         top

       A batch job might have one or more holds, which prevent the batch job
       from executing. A batch job from which all the holds have been
       removed becomes eligible for execution and is said to have been
       released. A batch job hold is removed by sending a request to the
       batch server that manages the batch job. The qrls utility is a user-
       accessible client of batch services that requests holds be removed
       from one or more batch jobs.

       The qrls utility shall remove one or more holds from those batch jobs
       for which a batch job_identifier is presented to the utility.

       The qrls utility shall remove holds from batch jobs in the order in
       which their batch job_identifiers are presented to the utility.

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

       The qrls utility shall remove holds on each batch job by sending a
       Release Job Request to the batch server that manages the batch job.

       The qrls utility shall not exit until the holds have been removed
       from the batch job corresponding to each successfully processed batch
       job_identifier.

OPTIONS         top

       The qrls utility shall conform to the Base Definitions volume of
       POSIX.1‐2008, Section 12.2, Utility Syntax Guidelines.

       The following option shall be supported by the implementation:

       −h hold_list
                 Define the types of holds to be removed from the batch job.

                 The qrls −h option shall accept a value for the hold_list
                 option-argument that is a string of alphanumeric characters
                 in the portable character set (see the Base Definitions
                 volume of POSIX.1‐2008, Section 6.1, Portable Character
                 Set).

                 The qrls utility shall accept a value for the hold_list
                 option-argument that is a string of one or more of the
                 characters 'u', 's', or 'o', or the single character 'n'.

                 For each unique character in the hold_list option-argument,
                 the qrls utility shall add a value to the Hold_Types
                 attribute of the batch job as follows, each representing a
                 different hold type:

                 u     USER

                 s     SYSTEM

                 o     OPERATOR

                 If any of these characters are duplicated in the hold_list
                 option-argument, the duplicates shall be ignored.

                 An existing Hold_Types attribute can be cleared by the
                 following hold type:

                 n     NO_HOLD

                 The qrls utility shall consider it an error if any hold
                 type other than 'n' is combined with hold type 'n'.

                 Strictly conforming applications shall not repeat any of
                 the characters 'u', 's', 'o', or 'n' within the hold_list
                 option-argument. The qrls utility shall permit the
                 repetition of characters, but shall not assign additional
                 meaning to the repeated characters.

                 An implementation may define other hold types. The
                 conformance document for an implementation shall describe
                 any additional hold types, how they are specified, their
                 internal behavior, and how they affect the behavior of the
                 utility.

                 If the −h option is not presented to the qrls utility, the
                 implementation shall remove the USER hold in the Hold_Types
                 attribute.

OPERANDS         top

       The qrls 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
       qrls:

       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

       None.

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 qrls 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 qrls
       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 qrls utility allows users, operators, and administrators to
       remove holds from jobs.

       The qrls utility does not support any job selection options or
       wildcard arguments. Users may acquire a list of jobs selected by
       attributes using the qselect utility. For example, a user could
       select all of their held jobs.

       The −h option allows the user to specify the type of hold that is to
       be removed. This option allows for USER, SYSTEM, OPERATOR, and
       implementation-defined hold types. The batch server that manages the
       batch job will verify whether the user is authorized to remove the
       specified hold for the batch job. If more than one type of hold has
       been placed on the batch job, a user may wish to remove only some of
       them.

       Mail is not required on release because the administrator has the
       tools and libraries to build this option if required.

       The qrls utility is a new utility vis-a-vis existing practice; it has
       been defined in this volume of POSIX.1‐2008 as the natural complement
       to the qhold utility.

FUTURE DIRECTIONS         top

       The qrls utility may be removed in a future version.
