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 out-
       put.
       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 sta-
       tus 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 sec-
       tion.
       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 identi-
       fied 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 destina-
       tion (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  syn-
       tax 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  Vari-
              ables  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
       and the -f option is not specified, the qstat utility shall display the

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_identi-
       fier 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 oper-
       ands.
       The other options of the qstat utility allow the user  to  control  the
       amount  of  information  displayed  and  the format in which it is dis-
       played. 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  implemen-
       tation-defined format.
       Historically,  the qstat utility has been a part of the NQS and its de-
       rivatives, the existing practice on which it is based.
FUTURE DIRECTIONS
       None.
