implementation of this interface may differ (consult the corresponding Linux

implemented on Linux.
qstat — show status of batch jobs
qstat [−f] job_identifier...
qstat −Q [−f] destination...
qstat −B [−f] server_name...
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.
The qstat utility shall conform to the Base Definitions volume of
POSIX.1‐2008, 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.
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).
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.1‐2008,
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_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.
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 batch queue
concurrently
- *
- The total number of batch jobs managed by the server
- *
- The status of the server
- *
- For each state, the number of batch jobs in that state and the name of the
state
- *
- Additional implementation-defined information, if any, about the
server
The standard error shall be used only for diagnostic messages.
The following exit values shall be returned:
- 0
- Successful completion.
- >0
- An error occurred.
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.
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.
The qstat utility may be removed in a future version.
