NAME
       qrls -- release batch jobs

SYNOPSIS
       qrls [[-h hold__list]] job__identifier...

DESCRIPTION
       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
       The qrls utility shall conform to the Base Definitions volume of
       POSIX.1-2017, 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.1-2017, 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
       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
       Not used.

INPUT FILES
       None.

ENVIRONMENT VARIABLES
       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.1-2017, 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 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
       None.

EXAMPLES
       None.

RATIONALE
       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.1-2017 as the natural complement
       to the qhold utility.

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