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
       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  success-
       fully,  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
       IEEE Std 1003.1-2001, 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-argu-
       ment  that is a string of alphanumeric characters in the portable char-
       acter set (see the Base  Definitions  volume  of  IEEE Std 1003.1-2001,
       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-argu-
       ment, 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  implementa-
       tion 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 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
              IEEE Std 1003.1-2001, Section  8.2,  Internationalization  Vari-
              ables  for 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_identi-
       fier  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 implementa-
       tion-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 IEEE Std 1003.1-2001 as the natural com-
       plement to the qhold utility.
FUTURE DIRECTIONS
       None.
