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

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

       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

       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.1‐2017, 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

                 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

                 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

                 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



       The following environment variables shall affect the execution of

       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).

                 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.



STDOUT         top


STDERR         top

       The standard error shall be used only for diagnostic messages.

OUTPUT FILES         top




EXIT STATUS         top

       The following exit values shall be returned:

        0    Successful completion.

       >0    An error occurred.


       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-

       The following sections are informative.



EXAMPLES         top


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.1‐2017 as the natural
       complement to the qhold utility.


       The qrls utility may be removed in a future version.
