QRLS(P) 			    POSIX Programmer's Manual				  QRLS(P)

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 cor-
       responding 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 differ-
       ent 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 implementa-
       tion  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, Inter-
	      nationalization Variables 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 interna-
	      tionalization 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 argu-
	      ments).

       LC_MESSAGES
	      Determine the locale that should be used to affect the format and contents of diag-
	      nostic 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 IEEE Std 1003.1-2001 as the natural complement to the qhold utility.

FUTURE DIRECTIONS
       None.
