PROLOG
       This manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may dif-
       fer (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  pre-
       sented to the utility.

       The  qrls utility shall remove holds from batch jobs in the order in which their batch job_identifiers are pre-
       sented 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 suc-
       cessfully 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-argument that  is  a  string  of  alphanumeric
       characters in the portable character 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-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
       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 Variables for the prece-
              dence 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 exam-
              ple, 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  writ-
              ten 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 attempt-
       ing 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 ver-
       ify 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 complement to the qhold utility.

FUTURE DIRECTIONS
       None.
