QSUB(1P) POSIX Programmer's Manual QSUB(1P)
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.
qsub — submit a script
qsub [-a date_time] [-A account_string] [-c interval]
[-C directive_prefix] [-e path_name] [-h] [-j join_list]
[-k keep_list] [-m mail_options] [-M mail_list] [-N name]
[-o path_name] [-p priority] [-q destination] [-r y|n]
[-S path_name_list] [-u user_list] [-v variable_list] [-V]
[-z] [script]
To submit a script is to create a batch job that executes the
script. A script is submitted by a request to a batch server. The
qsub utility is a user-accessible batch client that submits a
script.
Upon successful completion, the qsub utility shall have created a
batch job that will execute the submitted script.
The qsub utility shall submit a script by sending a Queue Job
Request to a batch server.
The qsub utility shall place the value of the following
environment variables in the Variable_List attribute of the batch
job: HOME, LANG, LOGNAME, PATH, MAIL, SHELL, and TZ. The name of
the environment variable shall be the current name prefixed with
the string PBS_O_.
Note: If the current value of the HOME variable in the
environment space of the qsub utility is /aa/bb/cc, then
qsub shall place PBS_O_HOME=/aa/bb/cc in the Variable_List
attribute of the batch job.
In addition to the variables described above, the qsub utility
shall add the following variables with the indicated values to the
variable list:
PBS_O_WORKDIR The absolute path of the current working directory
of the qsub utility process.
PBS_O_HOST The name of the host on which the qsub utility is
running.
The qsub 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:
-a date_time
Define the time at which a batch job becomes eligible
for execution.
The qsub utility shall accept an option-argument that
conforms to the syntax of the time operand of the touch
utility.

Note: The server that initiates execution of the batch
job will add other variables to the batch job's
environment; see Section 3.2.2.1, Batch Job
Execution.
The qsub utility shall set the Execution_Time attribute
of the batch job to the number of seconds since the
Epoch that is equivalent to the local time expressed by
the value of the date_time option-argument. The Epoch is
defined in the Base Definitions volume of POSIX.1‐2017,
Section 3.150, Epoch.
If the -a option is not presented to the qsub utility,
the utility shall set the Execution_Time attribute of
the batch job to a time (number of seconds since the
Epoch) that is earlier than the time at which the
utility exits.
-A account_string
Define the account to which the resource consumption of
the batch job should be charged.
The syntax of the account_string option-argument is
unspecified.
The qsub utility shall set the Account_Name attribute of
the batch job to the value of the account_string option-
argument.
If the -A option is not presented to the qsub utility,
the utility shall omit the Account_Name attribute from
the attributes of the batch job.
-c interval
Define whether the batch job should be checkpointed, and
if so, how often.
The qsub utility shall accept a value for the interval
option-argument that is one of the following:
n No checkpointing shall be performed on the
batch job (NO_CHECKPOINT).
s Checkpointing shall be performed only when the
batch server is shut down
(CHECKPOINT_AT_SHUTDOWN).
c Automatic periodic checkpointing shall be
performed at the Minimum_Cpu_Interval
attribute of the batch queue, in units of CPU
minutes (CHECKPOINT_AT_MIN_CPU_INTERVAL).
c=minutes Automatic periodic checkpointing shall be
performed every minutes of CPU time, or every
Minimum_Cpu_Interval minutes, whichever is
greater. The minutes argument shall conform to
the syntax for unsigned integers and shall be
greater than zero.
The qsub utility shall set the Checkpoint attribute of
the batch job to the value of the interval option-
argument.
If the -c option is not presented to the qsub utility,
the utility shall set the Checkpoint attribute of the
batch job to the single character 'u'
(CHECKPOINT_UNSPECIFIED).
-C directive_prefix
Define the prefix that declares a directive to the qsub
utility within the script.
The directive_prefix is not a batch job attribute; it
affects the behavior of the qsub utility.
If the -C option is presented to the qsub utility, and
the value of the directive_prefix option-argument is the
null string, the utility shall not scan the script file
for directives. If the -C option is not presented to the
qsub utility, then the value of the PBS_DPREFIX
environment variable is used. If the environment
variable is not defined, then #PBS encoded in the
portable character set is the default.
-e path_name
Define the path to be used for the standard error stream
of the batch job.
The qsub utility shall accept a path_name option-
argument which can be preceded by a host name element of
the form hostname:.
If the path_name option-argument constitutes an absolute
pathname, the qsub utility shall set the Error_Path
attribute of the batch job to the value of the path_name
option-argument.
If the path_name option-argument constitutes a relative
pathname and no host name element is specified, the qsub
utility shall set the Error_Path attribute of the batch
job to the value of the absolute pathname derived by
expanding the path_name option-argument relative to the
current directory of the process executing qsub.
If the path_name option-argument constitutes a relative
pathname and a host name element is specified, the qsub
utility shall set the Error_Path attribute of the batch
job to the value of the path_name option-argument
without expansion. The host name element shall be
included.
If the path_name option-argument does not include a host
name element, the qsub utility shall prefix the pathname
with hostname:, where hostname is the name of the host
upon which the qsub utility is being executed.
If the -e option is not presented to the qsub utility,
the utility shall set the Error_Path attribute of the
batch job to the host name and path of the current
directory of the submitting process and the default
filename.
The default filename for standard error has the
following format:
job_name.esequence_number
-h Specify that a USER hold is applied to the batch job.
The qsub utility shall set the value of the Hold_Types
attribute of the batch job to the value USER.
If the -h option is not presented to the qsub utility,
the utility shall set the Hold_Types attribute of the
batch job to the value NO_HOLD.
-j join_list
Define which streams of the batch job are to be merged.
The qsub -j option shall accept a value for the
join_list option-argument that is a string of
alphanumeric characters in the portable character set
(see the Base Definitions volume of POSIX.1‐2017,
Section 6.1, Portable Character Set).
The qsub utility shall accept a join_list option-
argument that consists of one or more of the characters
'e' and 'o', or the single character 'n'.
All of the other batch job output streams specified will
be merged into the output stream represented by the
character listed first in the join_list option-argument.
For each unique character in the join_list option-
argument, the qsub utility shall add a value to the
Join_Path attribute of the batch job as follows, each
representing a different batch job stream to join:
e The standard error of the batch job
(JOIN_STD_ERROR).
o The standard output of the batch job
(JOIN_STD_OUTPUT).
An existing Join_Path attribute can be cleared by the
following join type:
n NO_JOIN
If 'n' is specified, then no files are joined. The qsub
utility shall consider it an error if any join type
other than 'n' is combined with join type 'n'.
Strictly conforming applications shall not repeat any of
the characters 'e', 'o', or 'n' within the join_list
option-argument. The qsub utility shall permit the
repetition of characters, but shall not assign
additional meaning to the repeated characters.
An implementation may define other join types. The
conformance document for an implementation shall
describe any additional batch job streams, how they are
specified, their internal behavior, and how they affect
the behavior of the utility.
If the -j option is not presented to the qsub utility,
the utility shall set the value of the Join_Path
attribute of the batch job to NO_JOIN.
-k keep_list
Define which output of the batch job to retain on the
execution host.
The qsub -k option shall accept a value for the
keep_list option-argument that is a string of
alphanumeric characters in the portable character set
(see the Base Definitions volume of POSIX.1‐2017,
Section 6.1, Portable Character Set).
The qsub utility shall accept a keep_list option-
argument that consists of one or more of the characters
'e' and 'o', or the single character 'n'.
For each unique character in the keep_list option-
argument, the qsub utility shall add a value to the
Keep_Files attribute of the batch job as follows, each
representing a different batch job stream to keep:
e The standard error of the batch job
(KEEP_STD_ERROR).
o The standard output of the batch job
(KEEP_STD_OUTPUT).
If both 'e' and 'o' are specified, then both files are
retained. An existing Keep_Files attribute can be
cleared by the following keep type:
n NO_KEEP
If 'n' is specified, then no files are retained. The
qsub utility shall consider it an error if any keep type
other than 'n' is combined with keep type 'n'.
Strictly conforming applications shall not repeat any of
the characters 'e', 'o', or 'n' within the keep_list
option-argument. The qsub utility shall permit the
repetition of characters, but shall not assign
additional meaning to the repeated characters.
An implementation may define other keep types. The
conformance document for an implementation shall
describe any additional keep types, how they are
specified, their internal behavior, and how they affect
the behavior of the utility. If the -k option is not
presented to the qsub utility, the utility shall set the
Keep_Files attribute of the batch job to the value
NO_KEEP.
-m mail_options
Define the points in the execution of the batch job at
which the batch server that manages the batch job shall
send mail about a change in the state of the batch job.
The qsub -m option shall accept a value for the
mail_options option-argument that is a string of
alphanumeric characters in the portable character set
(see the Base Definitions volume of POSIX.1‐2017,
Section 6.1, Portable Character Set).
The qsub utility shall accept a value for the
mail_options option-argument that is a string of one or
more of the characters 'e', 'b', and 'a', or the single
character 'n'.
For each unique character in the mail_options option-
argument, the qsub utility shall add a value to the
Mail_Users attribute of the batch job as follows, each
representing a different time during the life of a batch
job at which to send mail:
e MAIL_AT_EXIT
b MAIL_AT_BEGINNING
a MAIL_AT_ABORT
If any of these characters are duplicated in the
mail_options option-argument, the duplicates shall be
ignored.
An existing Mail_Points attribute can be cleared by the
following mail type:
n NO_MAIL
If 'n' is specified, then mail is not sent. The qsub
utility shall consider it an error if any mail type
other than 'n' is combined with mail type 'n'.
Strictly conforming applications shall not repeat any of
the characters 'e', 'b', 'a', or 'n' within the
mail_options option-argument.
The qsub utility shall permit the repetition of
characters, but shall not assign additional meaning to
the repeated characters. An implementation may define
other mail types. The conformance document for an
implementation shall describe any additional mail types,
how they are specified, their internal behavior, and how
they affect the behavior of the utility.
If the -m option is not presented to the qsub utility,
the utility shall set the Mail_Points attribute to the
value MAIL_AT_ABORT.
-M mail_list
Define the list of users to which a batch server that
executes the batch job shall send mail, if the server
sends mail about the batch job.
The syntax of the mail_list option-argument is
unspecified.
If the implementation of the qsub utility uses a name
service to locate users, the utility should accept the
syntax used by the name service.
If the implementation of the qsub utility does not use a
name service to locate users, the implementation should
accept the following syntax for user names:
mail_address[,,mail_address,, ...]
The interpretation of mail_address is implementation-
defined.
The qsub utility shall set the Mail_Users attribute of
the batch job to the value of the mail_list option-
argument.
If the -M option is not presented to the qsub utility,
the utility shall place only the user name and host name
for the current process in the Mail_Users attribute of
the batch job.
-N name Define the name of the batch job.
The qsub -N option shall accept a value for the name
option-argument that is a string of up to 15
alphanumeric characters in the portable character set
(see the Base Definitions volume of POSIX.1‐2017,
Section 6.1, Portable Character Set) where the first
character is alphabetic.
The qsub utility shall set the value of the Job_Name
attribute of the batch job to the value of the name
option-argument.
If the -N option is not presented to the qsub utility,
the utility shall set the Job_Name attribute of the
batch job to the name of the script argument from which
the directory specification if any, has been removed.
If the -N option is not presented to the qsub utility,
and the script is read from standard input, the utility
shall set the Job_Name attribute of the batch job to the
value STDIN.
-o path_name
Define the path for the standard output of the batch
job.
The qsub utility shall accept a path_name option-
argument that conforms to the syntax of the path_name
element defined in the System Interfaces volume of
POSIX.1‐2017, which can be preceded by a host name
element of the form hostname:.
If the path_name option-argument constitutes an absolute
pathname, the qsub utility shall set the Output_Path
attribute of the batch job to the value of the path_name
option-argument without expansion.
If the path_name option-argument constitutes a relative
pathname and no host name element is specified, the qsub
utility shall set the Output_Path attribute of the batch
job to the pathname derived by expanding the value of
the path_name option-argument relative to the current
directory of the process executing the qsub.
If the path_name option-argument constitutes a relative
pathname and a host name element is specified, the qsub
utility shall set the Output_Path attribute of the batch
job to the value of the path_name option-argument
without expansion.
If the path_name option-argument does not specify a host
name element, the qsub utility shall prefix the pathname
with hostname:, where hostname is the name of the host
upon which the qsub utility is executing.
If the -o option is not presented to the qsub utility,
the utility shall set the Output_Path attribute of the
batch job to the host name and path of the current
directory of the submitting process and the default
filename.
The default filename for standard output has the
following format:
job_name.osequence_number
-p priority
Define the priority the batch job should have relative
to other batch jobs owned by the batch server.
The qsub utility shall set the Priority attribute of the
batch job to the value of the priority option-argument.
If the -p option is not presented to the qsub utility,
the value of the Priority attribute is implementation-
defined.
The qsub utility shall accept a value for the priority
option-argument that conforms to the syntax for signed
decimal integers, and which is not less than -1024 and
not greater than 1023.
-q destination
Define the destination of the batch job.
The destination is not a batch job attribute; it
determines the batch server, and possibly the batch
queue, to which the qsub utility batch queues the batch
job.
The qsub utility shall submit the script to the batch
server named by the destination option-argument or the
server that owns the batch queue named in the
destination option-argument.
The qsub utility shall accept an option-argument for the
-q option that conforms to the syntax for a destination
(see Section 3.3.2, Destination).
If the -q option is not presented to the qsub utility,
the qsub utility shall submit the batch job to the
default destination. The mechanism for determining the
default destination is implementation-defined.
-r y|n Define whether the batch job is rerunnable.
If the value of the option-argument is y, the qsub
utility shall set the Rerunable attribute of the batch
job to TRUE.
If the value of the option-argument is n, the qsub
utility shall set the Rerunable attribute of the batch
job to FALSE.
If the -r option is not presented to the qsub utility,
the utility shall set the Rerunable attribute of the
batch job to TRUE.
-S path_name_list
Define the pathname to the shell under which the batch
job is to execute.
The qsub utility shall accept a path_name_list option-
argument that conforms to the following syntax:
pathname[@host][,,pathname[@host],, ...]
The qsub utility shall allow only one pathname for a
given host name. The qsub utility shall allow only one
pathname that is missing a corresponding host name.
The qsub utility shall add a value to the
Shell_Path_List attribute of the batch job for each
entry in the path_name_list option-argument.
If the -S option is not presented to the qsub utility,
the utility shall set the Shell_Path_List attribute of
the batch job to the null string.
The conformance document for an implementation shall
describe the mechanism used to set the default shell and
determine the current value of the default shell. An
implementation shall provide a means for the
installation to set the default shell to the login shell
of the user under which the batch job is to execute. See
Section 3.3.3, Multiple Keyword-Value Pairs for a means
of removing keyword=value (and value@keyword) pairs and
other general rules for list-oriented batch job
attributes.
-u user_list
Define the user name under which the batch job is to
execute.
The qsub utility shall accept a user_list option-
argument that conforms to the following syntax:
username[@host][,,username[@host],, ...]
The qsub utility shall accept only one user name that is
missing a corresponding host name. The qsub utility
shall accept only one user name per named host.
The qsub utility shall add a value to the User_List
attribute of the batch job for each entry in the
user_list option-argument.
If the -u option is not presented to the qsub utility,
the utility shall set the User_List attribute of the
batch job to the user name from which the utility is
executing. See Section 3.3.3, Multiple Keyword-Value
Pairs for a means of removing keyword=value (and
value@keyword) pairs and other general rules for list-
oriented batch job attributes.
-v variable_list
Add to the list of variables that are exported to the
session leader of the batch job.
A variable_list is a set of strings of either the form
<variable> or <variable=value>, delimited by <comma>
characters.
If the -v option is presented to the qsub utility, the
utility shall also add, to the environment Variable_List
attribute of the batch job, every variable named in the
environment variable_list option-argument and,
optionally, values of specified variables.
If a value is not provided on the command line, the qsub
utility shall set the value of each variable in the
environment Variable_List attribute of the batch job to
the value of the corresponding environment variable for
the process in which the utility is executing; see Table
4-19, Environment Variable Values (Utilities).
A conforming application shall not repeat a variable in
the environment variable_list option-argument.
The qsub utility shall not repeat a variable in the
environment Variable_List attribute of the batch job.
See Section 3.3.3, Multiple Keyword-Value Pairs for a
means of removing keyword=value (and value@keyword)
pairs and other general rules for list-oriented batch
job attributes.
-V Specify that all of the environment variables of the
process are exported to the context of the batch job.
The qsub utility shall place every environment variable
in the process in which the utility is executing in the
list and shall set the value of each variable in the
attribute to the value of that variable in the process.
-z Specify that the utility does not write the batch
job_identifier of the created batch job to standard
output.
If the -z option is presented to the qsub utility, the
utility shall not write the batch job_identifier of the
created batch job to standard output.
If the -z option is not presented to the qsub utility,
the utility shall write the identifier of the created
batch job to standard output.
The qsub utility shall accept a script operand that indicates the
path to the script of the batch job.
If the script operand is not presented to the qsub utility, or if
the operand is the single-character string '-', the utility shall
read the script from standard input.
If the script represents a partial path, the qsub utility shall
expand the path relative to the current directory of the process
executing the utility.
The qsub utility reads the script of the batch job from standard
input if the script operand is omitted or is the single character
'-'.
In addition to binding the file indicated by the script operand to
the batch job, the qsub utility reads the script file and acts on
directives in the script.
The following environment variables shall affect the execution of
qsub:
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_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.
LOGNAME Determine the login name of the user.
PBS_DPREFIX
Determine the default prefix for directives within the
script.
SHELL Determine the pathname of the preferred command language
interpreter of the user.
TZ Determine the timezone used to interpret the date-time
option-argument. If TZ is unset or null, an unspecified
default timezone shall be used.
Once created, a batch job exists until it exits, aborts, or is
deleted.
After a batch job is created by the qsub utility, batch servers
might route, execute, modify, or delete the batch job.
The qsub utility writes the batch job_identifier assigned to the
batch job to standard output, unless the -z option is specified.
The standard error shall be used only for diagnostic messages.
None.
Script Preservation
The qsub utility shall make the script available to the server
executing the batch job in such a way that the server executes the
script as it exists at the time of submission.
The qsub utility can send a copy of the script to the server with
the Queue Job Request or store a temporary copy of the script in a
location specified to the server.
Option Specification
A script can contain directives to the qsub utility.
The qsub utility shall scan the lines of the script for
directives, skipping blank lines, until the first line that begins
with a string other than the directive string; if directives occur
on subsequent lines, the utility shall ignore those directives.
Lines are separated by a <newline>. If the first line of the
script begins with "#!" or a <colon> (':'), then it is skipped.
The qsub utility shall process a line in the script as a directive
if and only if the string of characters from the first non-white-
space character on the line until the first <space> or <tab> on
the line match the directive prefix. If a line in the script
contains a directive and the final characters of the line are
<backslash> and <newline>, then the next line shall be interpreted
as a continuation of that directive.
The qsub utility shall process the options and option-arguments
contained on the directive prefix line using the same syntax as if
the options were input on the qsub utility.
The qsub utility shall continue to process a directive prefix line
until after a <newline> is encountered. An implementation may
ignore lines which, according to the syntax of the shell that will
interpret the script, are comments. An implementation shall
describe in the conformance document the format of any shell
comments that it will recognize.
If an option is present in both a directive and the arguments to
the qsub utility, the utility shall ignore the option and the
corresponding option-argument, if any, in the directive.
If an option that is present in the directive is not present in
the arguments to the qsub utility, the utility shall process the
option and the option-argument, if any.
In order of preference, the qsub utility shall select the
directive prefix from one of the following sources:
* If the -C option is presented to the utility, the value of the
directive_prefix option-argument
* If the environment variable PBS_DPREFIX is defined, the value
of that variable
* The four-character string "#PBS" encoded in the portable
character set
If the -C option is present in the script file it shall be
ignored.
The following exit values shall be returned:
0 Successful completion.
>0 An error occurred.
Default.
The following sections are informative.
None.
None.
The qsub utility allows users to create a batch job that will
process the script specified as the operand of the utility.
The options of the qsub utility allow users to control many
aspects of the queuing and execution of a batch job.
The -a option allows users to designate the time after which the
batch job will become eligible to run. By specifying an execution
time, users can take advantage of resources at off-peak hours,
synchronize jobs with chronologically predictable events, and
perhaps take advantage of off-peak pricing of computing time. For
these reasons and others, a timing option is existing practice on
the part of almost every batch system, including NQS.
The -A option allows users to specify the account that will be
charged for the batch job. Support for account is not mandatory
for conforming batch servers.
The -C option allows users to prescribe the prefix for directives
within the script file. The default prefix "#PBS" may be
inappropriate if the script will be interpreted with an alternate
shell, as specified by the -S option.
The -c option allows users to establish the checkpointing interval
for their jobs. A checkpointing system, which is not defined by
this volume of POSIX.1‐2017, allows recovery of a batch job at the
most recent checkpoint in the event of a crash. Checkpointing is
typically used for jobs that consume expensive computing time or
must meet a critical schedule. Users should be allowed to make the
tradeoff between the overhead of checkpointing and the risk to the
timely completion of the batch job; therefore, this volume of
POSIX.1‐2017 provides the checkpointing interval option. Support
for checkpointing is optional for batch servers.
The -e option allows users to redirect the standard error streams
of their jobs to a non-default path. For example, if the submitted
script generally produces a great deal of useless error output, a
user might redirect the standard error output to the null device.
Or, if the file system holding the default location (the home
directory of the user) has too little free space, the user might
redirect the standard error stream to a file in another file
system.
The -h option allows users to create a batch job that is held
until explicitly released. The ability to create a held job is
useful when some external event must complete before the batch job
can execute. For example, the user might submit a held job and
release it when the system load has dropped.
The -j option allows users to merge the standard error of a batch
job into its standard output stream, which has the advantage of
showing the sequential relationship between output and error
messages.
The -m option allows users to designate those points in the
execution of a batch job at which mail will be sent to the
submitting user, or to the account(s) indicated by the -M option.
By requesting mail notification at points of interest in the life
of a job, the submitting user, or other designated users, can
track the progress of a batch job.
The -N option allows users to associate a name with the batch job.
The job name in no way affects the processing of the batch job,
but rather serves as a mnemonic handle for users. For example, the
batch job name can help the user distinguish between multiple jobs
listed by the qstat utility.
The -o option allows users to redirect the standard output stream.
A user might, for example, wish to redirect to the null device the
standard output stream of a job that produces copious yet
superfluous output.
The -P option allows users to designate the relative priority of a
batch job for selection from a queue.
The -q option allows users to specify an initial queue for the
batch job. If the user specifies a routing queue, the batch server
routes the batch job to another queue for execution or further
routing. If the user specifies a non-routing queue, the batch
server of the queue eventually executes the batch job.
The -r option allows users to control whether the submitted job
will be rerun if the controlling batch node fails during execution
of the batch job. The -r option likewise allows users to indicate
whether or not the batch job is eligible to be rerun by the qrerun
utility. Some jobs cannot be correctly rerun because of changes
they make in the state of databases or other aspects of their
environment. This volume of POSIX.1‐2017 specifies that the
default, if the -r option is not presented to the utility, will be
that the batch job cannot be rerun, since the result of rerunning
a non-rerunnable job might be catastrophic.
The -S option allows users to specify the program (usually a
shell) that will be invoked to process the script of the batch
job. This option has been modified to allow a list of shell names
and locations associated with different hosts.
The -u option is useful when the submitting user is authorized to
use more than one account on a given host, in which case the -u
option allows the user to select from among those accounts. The
option-argument is a list of user-host pairs, so that the
submitting user can provide different user identifiers for
different nodes in the event the batch job is routed. The -u
option provides a lot of flexibility to accommodate sites with
complex account structures. Users that have the same user
identifier on all the hosts they are authorized to use will not
need to use the -u option.
The -V option allows users to export all their current environment
variables, as of the time the batch job is submitted, to the
context of the processes of the batch job.
The -v option allows users to export specific environment
variables from their current process to the processes of the batch
job.
The -z option allows users to suppress the writing of the batch
job identifier to standard output. The -z option is an existing
NQS practice that has been standardized.
Historically, the qsub utility has served the batch job-submission
function in the NQS system, the existing practice on which it is
based. Some changes and additions have been made to the qsub
utility in this volume of POSIX.1‐2017, vis-a-vis NQS, as a result
of the growing pool of experience with distributed batch systems.
The set of features of the qsub utility as defined in this volume
of POSIX.1‐2017 appears to incorporate all the common existing
practice on potentially conforming platforms.
The qsub utility may be removed in a future version.
