qhold - hold back Grid Engine jobs from execution


       qhold [-h {u|o|s},...]  [-help] [job/task_id_list]

       qhold [-h {u|o|s},...]  [-help] -u user_list


       Qhold provides a means for a user/operator/manager to place so called
       holds on one or more jobs pending scheduling for execution.  As long as
       any type of hold is assigned to a job, the job is not eligible for

       Holds can be removed with the qrls(1) or qalter(1) command.

       There are three different types of holds:

       user   User holds can be assigned and removed by managers, operators
              and the owner of the jobs.

              Operator holds can be assigned and removed by managers and

       system System holds can be assigned and removed by managers only.

       If no hold type is specified with the -h option (see below) the user
       hold is assumed by default.

       An alternate way to assign holds to jobs is the qsub(1) or the
       qalter(1) command (see the -h option).


       -h {u|o|s},...
              Assign a u(ser), o(perator) or s(system) hold, or a combination
              thereof, to one or more jobs.

       -help  Prints a listing of all options.

       -u username,...
              Changes are only made on those jobs which were submitted by
              users specified in the list of usernames.  Managers are allowed
              to use the qhold -u "*" command to set a hold for all jobs of
              all users.

              If a user uses the -u switch, the user may specify an additional

              Specified by the following form:


              If present, the task_range restricts the effect of the qhold
              operation to the array job task range specified as suffix to the
              job id (see the -t option to qsub(1) for further details on
              array jobs).

              The task range specifier has the form n[-m[:s]]. The range may
              be a single number, a  simple range  of the form n-m or a range
              with a step size s.

              Instead of job/task_id_list it is possible to use the keyword
              'all' to modify the hold state for all jobs of the current user.


       SGE_ROOT       Specifies the location of the Grid Engine standard
                      configuration files.

       SGE_CELL       If set, specifies the default Grid Engine cell. To
                      address a Grid Engine cell qhold uses (in the order of

                             The name of the cell specified in the environment
                             variable SGE_CELL, if it is set.

                             The name of the default cell, i.e. default.

                      If set, specifies that debug information should be
                      written to stderr. In addition the level of detail in
                      which debug information is generated is defined.

                      If set, specifies the tcp port on which sge_qmaster(8)
                      is expected to listen for communication requests.  Most
                      installations will use a services map entry for the
                      service "sge_qmaster" instead to define that port.
