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
       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, Inter-
	      nationalization 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 interna-
	      tionalization 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  argu-
	      ments).

       LC_MESSAGES
	      Determine the locale that should be used to affect the format and contents of diag-
	      nostic 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 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 op-
       erand:

	* 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

	* 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 success-
       fully processed operand:

	* The batch queue name

	* 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 speci-
       fied, 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

	* 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 follow-
       ing 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 speci-

	* 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

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 des-
       tination  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 sta-
       tus 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 for-
       mat.

       Historically, the qstat utility has been a part of the NQS and its derivatives, the exist-
       ing practice on which it is based.

FUTURE DIRECTIONS
       None.
