QRLS(1P)		   POSIX Programmer's Manual		      QRLS(1P)

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
       POSIX.1‐2008, 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  vol‐
		 ume of POSIX.1‐2008, 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	 char‐
		 acters '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 fol‐
		 lowing 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 confor‐
		 mance 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 Section 3.3.1, Batch Job Identi‐
       fier).

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	 vari‐
		 ables	that are unset or null. (See the Base Definitions vol‐
		 ume of POSIX.1‐2008, Section 8.2, Internationalization	 Vari‐
		 ables	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 POSIX.1‐2008 as the natural complement
       to the qhold utility.

FUTURE DIRECTIONS
       The qrls utility may be removed in a future version.
