NAME
qstat - show status of batch jobs
SYNOPSIS
qstat [-f] job_identifier ...
qstat -Q [-f] destination ...
qstat -B [-f] server_name ...
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.
OPTIONS
The qstat utility shall conform to the Base Definitions volume
of IEEE Std 1003.1-2001, 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.
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 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 Batch Job
Identifier ).
STDIN
Not used.
INPUT FILES
None.
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
IEEE Std 1003.1-2001, Section 8.2, Internationalization Variables
for
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.
ASYNCHRONOUS EVENTS
Default.
STDOUT
If an operand presented to the qstat utility is a batch job_identifier

The batch job state
- *
-
The batch job location

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
- *
-

If the operands presented to the qstat utility are batch server

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 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.
APPLICATION USAGE
None.
EXAMPLES
None.
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.
FUTURE DIRECTIONS
None.
