QRLS(1P) POSIX Programmer's Manual QRLS(1P)
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.
qrls — release batch jobs
qrls [−h hold_list] job_identifier...
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.
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
volume 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
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.
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).
Not used.
None.
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.1‐2008, 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.
Default.
None.
The standard error shall be used only for diagnostic messages.
None.
None.
The following exit values shall be returned:
0 Successful completion.
>0 An error occurred.
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.
None.
None.
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.1‐2008 as the natural complement
to the qhold utility.
The qrls utility may be removed in a future version.
