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 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.
