Имя (Name)
qrls — release batch jobs
Синопсис (Synopsis)
qrls [-h hold_list] job_identifier...
Описание (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.
Параметры (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.
Операнды (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).
Стандартный ввод (Stdin)
Not used.
Входные файлы (Input files)
None.
Переменные окружения (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.
Асинхронные события (Asynchronous events)
Default.
Стандартный вывод (Stdout)
None.
Стандартный вывод сообщений (Stderr)
The standard error shall be used only for diagnostic messages.
Выходные файлы (Output files)
None.
Расширенное описание (Extended description)
None.
Статус выхода (Exit)
The following exit values shall be returned:
0 Successful completion.
>0 An error occurred.
Последствия ошибок (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.
Использование в приложениях (Application usage)
None.
Примеры (Examples)
None.
Обоснование (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.
Будущие направления (Future directions)
The qrls utility may be removed in a future version.
