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.
