       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 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 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  addi-
       tional 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 precedence  of  international-
              ization 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 stan-
              dard 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 IEEE Std 1003.1-2001
       as the natural complement to the qhold utility.

FUTURE DIRECTIONS
       None.
