## PROLOG



           This manual page is part of the POSIX Programmer's Manual.  The
           Linux implementation of this interface may differ (consult the

## 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_identifier_ s 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_identifier_ s, 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.1‐2017, _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 POSIX.1‐2017,
                     _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 _Section 3.3.1_ , _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 POSIX.1‐2017, _Section 8.2_ ,
                     _Internationalization Variables_ 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_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 POSIX.1‐2017 as the natural
           complement to the _qhold_ utility.
    


## FUTURE DIRECTIONS



           The _qrls_ utility may be removed in a future version.
