qstat — show status of batch jobs
Синопсис (Synopsis)
qstat [-f] job_identifier...
qstat -Q [-f] destination...
qstat -B [-f] server_name...
Описание (Description)
The status of a batch job, batch queue, or batch server is
obtained by a request to the server. The qstat utility is a user-
accessible batch client that requests the status of one or more
batch jobs, batch queues, or servers, and writes the status
information to standard output.
For each successfully processed batch job_identifier, the qstat
utility shall display information about the corresponding batch
job.
For each successfully processed destination, the qstat utility
shall display information about the corresponding batch queue.
For each successfully processed server name, the qstat utility
shall display information about the corresponding server.
The qstat utility shall acquire batch job status information by
sending a Job Status Request to a batch server. The qstat utility
shall acquire batch queue status information by sending a Queue
Status Request to a batch server. The qstat utility shall acquire
server status information by sending a Server Status Request to a
batch server.
Параметры (Options)
The qstat utility shall conform to the Base Definitions volume of
POSIX.1‐2017, Section 12.2, Utility Syntax Guidelines.
The following options shall be supported by the implementation:
-f Specify that a full display is produced.
The minimum contents of a full display are specified in
the STDOUT section.
Additional contents and format of a full display are
implementation-defined.
-Q Specify that the operand is a destination.
The qstat utility shall display information about each
batch queue at each destination identified as an
operand.
-B Specify that the operand is a server name.
The qstat utility shall display information about each
server identified as an operand.
Операнды (Operands)
If the -Q option is presented to the qstat utility, the utility
shall accept one or more operands that conform to the syntax for
a destination (see Section 3.3.2, Destination).
If the -B option is presented to the qstat utility, the utility
shall accept one or more server_name operands.
If neither the -B nor the -Q option is presented to the qstat
utility, the 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
qstat:
HOME Determine the pathname of the user's home directory.
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_COLLATE
Determine the locale for the behavior of ranges,
equivalence classes, and multi-character collating
elements within regular expressions.
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.
LC_NUMERIC
Determine the locale for selecting the radix character
used when writing floating-point formatted output.
Асинхронные события (Asynchronous events)
Default.
Стандартный вывод (Stdout)
If an operand presented to the qstat utility is a batch
job_identifier and the -f option is not specified, the qstat
utility shall display the following items on a single line, in
the stated order, with white space between each item, for each
successfully processed operand:
* The batch job_identifier
* The batch job name
* The Job_Owner attribute
* The CPU time used by the batch job
* The batch job state
* The batch job location
If an operand presented to the qstat utility is a batch
job_identifier and the -f option is specified, the qstat utility
shall display the following items for each success fully
processed operand:
* The batch job_identifier
* The batch job name
* The Job_Owner attribute
* The execution user ID
* The CPU time used by the batch job
* The batch job state
* The batch job location
* Additional implementation-defined information, if any, about
the batch job or batch queue
If an operand presented to the qstat utility is a destination,
the -Q option is specified, and the -f option is not specified,
the qstat utility shall display the following items on a single
line, in the stated order, with white space between each item,
for each successfully processed operand:
* The batch queue name
* The maximum number of batch jobs that shall be run in the
batch queue concurrently
* The total number of batch jobs in the batch queue
* The status of the batch queue
* For each state, the number of batch jobs in that state in the
batch queue and the name of the state
* The type of batch queue (execution or routing)
If the operands presented to the qstat utility are destinations,
the -Q option is specified, and the -f option is specified, the
qstat utility shall display the following items for each
successfully processed operand:
* The batch queue name
* The maximum number of batch jobs that shall be run in the
batch queue concurrently
* The total number of batch jobs in the batch queue
* The status of the batch queue
* For each state, the number of batch jobs in that state in the
batch queue and the name of the state
* The type of batch queue (execution or routing)
* Additional implementation-defined information, if any, about
the batch queue
If the operands presented to the qstat utility are batch server
names, the -B option is specified, and the -f option is not
specified, the qstat utility shall display the following items on
a single line, in the stated order, with white space between each
item, for each successfully processed operand:
* The batch server name
* The maximum number of batch jobs that shall be run in the
batch queue concurrently
* The total number of batch jobs managed by the batch server
* The status of the batch server
* For each state, the number of batch jobs in that state and
the name of the state
If the operands presented to the qstat utility are server names,
the -B option is specified, and the -f option is specified, the
qstat utility shall display the following items for each
successfully processed operand:
* The server name
* The maximum number of batch jobs that shall be run in the

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 qstat 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 qstat utility waits to output the diagnostic message while
attempting to locate the batch job on other servers is
implementation-defined.
The following sections are informative.

Обоснование (Rationale)
The qstat utility allows users to display the status of jobs and
list the batch jobs in queues.
The operands of the qstat utility may be either job identifiers,
queues (specified as destination identifiers), or batch server
names. The -Q and -B options, or absence thereof, indicate the
nature of the operands.
The other options of the qstat utility allow the user to control
the amount of information displayed and the format in which it is
displayed. Should a user wish to display the status of a set of
jobs that match a selection criteria, the qselect utility may be
used to acquire such a list.
The -f option allows users to request a ``full'' display in an
implementation-defined format.
Historically, the qstat utility has been a part of the NQS and
its derivatives, the existing practice on which it is based.
Будущие направления (Future directions)
The qstat utility may be removed in a future version.
