       Default.

       In  addition  to  the  default  behavior,  the  qhold 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 qhold utility waits to output the
       diagnostic message while attempting to locate the job on other servers is implementation-defined.

IEEE/The Open Group                                   2017                                         QHOLD(1POSIX)

       A  hold is placed on a batch job by a request to the batch server that manages the batch job. A batch job
       that has one or more holds is not eligible for execution. The qhold utility is a  user-accessible  client
       of batch services that requests one or more types of hold to be placed on one or more batch jobs.

       The  qhold utility shall place holds on those batch jobs for which a batch job_identifier is presented to
       the utility.

       The qhold utility shall place holds on batch jobs in the order in which their batch  job_identifiers  are
       presented  to  the  utility. If the qhold utility fails to process any batch job_identifier successfully,
       the utility shall proceed to process the remaining batch job_identifiers, if any.

       The qhold utility shall place holds on each batch job by sending a HoldJobRequest to the  batch  server
       that manages the batch job.

       The  qhold  utility  shall  not  exit until holds have been placed on the batch job corresponding to each
       successfully processed batch job_identifier.

       The following environment variables shall affect the execution of qhold:

       LANG      Provide a default value for the internationalization variables that are unset or null. (See the
                 Base Definitions volume  of  POSIX.1‐2017,  Section8.2,  InternationalizationVariables  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.

       None.

       The following exit values shall be returned:

        0    Successful completion.

       >0    An error occurred.

       None.

       The qhold utility may be removed in a future version.

       None.

       qhold — hold batch jobs

       The qhold utility shall accept one or more operands that conform to the syntax for a batch job_identifier
       (see Section3.3.1, BatchJobIdentifier).

       The qhold utility shall conform to the Base Definitions volume of  POSIX.1‐2017,  Section12.2,  UtilitySyntaxGuidelines.

       The following option shall be supported by the implementation:

       -hhold_list
                 Define the types of holds to be placed on the batch job.

                 The  qhold-h option shall accept a value for the hold_list option-argument that is a string of
                 alphanumeric characters in the portable character set  (see  the  Base  Definitions  volume  of
                 POSIX.1‐2017, Section6.1, PortableCharacterSet).

                 The  qhold  utility  shall accept a value for the hold_list option-argument that is a string of
                 one or more of the characters 'u', 's', or 'o', or the single character 'n'.

                 For each unique character in the hold_list option-argument, the qhold utility shall add a value
                 to the Hold_Types attribute of the batch job as follows, each  representing  a  different  hold
                 type:

                 u     USER

                 s     SYSTEM

                 o     OPERATOR

                 If  any  of  these  characters  are duplicated in the hold_list option-argument, the duplicates
                 shall be ignored.

                 An existing Hold_Types attribute can be cleared by the following hold type:

                 n     NO_HOLD

                 The qhold utility shall consider it an error if any hold type other than 'n' is  combined  with
                 hold type 'n'.

                 Strictly  conforming  applications shall not repeat any of the characters 'u', 's', 'o', or 'n'
                 within the hold_list  option-argument.  The  qhold  utility  shall  permit  the  repetition  of
                 characters, but shall not assign additional meaning to the repeated characters.

                 An  implementation  may define other hold types. The conformance document for an implementation
                 shall describe any additional hold types, how they are specified, their internal behavior,  and
                 how they affect the behavior of the utility.

                 If  the  -h  option  is  not  presented  to the qhold utility, the implementation shall set the
                 Hold_Types attribute to USER.

       None.

       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.

       The qhold utility allows users to place a hold on one or more jobs. A hold makes a batch  job  ineligible
       for execution.

       The  qhold  utility has options that allow the user to specify the type of hold.  Should the user wish to
       place a hold on a set of jobs that meet a selection criteria, such a list of jobs can be  acquired  using
       the qselect utility.

       The  -h  option  allows the user to specify the type of hold that is to be placed on the job. This option
       allows for USER, SYSTEM, OPERATOR, and implementation-defined hold types. The USER and OPERATOR holds are
       distinct. The batch server that manages the batch job will verify that the user is authorized to set  the
       specified hold for the batch job.

       Mail  is  not required on hold because the administrator has the tools and libraries to build this option
       if he or she wishes.

       Historically, the qhold utility has been a part of some existing  batch  systems,  although  it  has  not
       traditionally been a part of the NQS.
