The qhold command is essentially a special case of the qalter command.
Command qhold puts a job, which hasn't been started yet on hold so that it will not be scheduled for execution by the SGE till the hold is removed. Requires the job-id as argument. qrls command releases the job
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 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 option -h 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
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 Hold Job Request 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.
qhold [-h hold_list] job_identifier ...
The qhold utility shall conform to the Base Definitions volume of IEEE Std 1003.1-2001, Section 12.2, Utility Syntax Guidelines.
The following option shall be supported by the implementation:
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:
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:
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.
The qhold utility shall accept one or more operands that conform to the syntax for a batch job_identifier (see Batch Job Identifier ).
Stdin is not used.There are no input files
The following environment variables shall affect the execution of qhold:
The standard error shall be used only for diagnostic messages.
The following exit values shall be returned:
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.

I'm running some jobs on an SGE cluster. Is there a way to make qstat show me only jobs that are not on hold?
qstat -s p shows pending jobs, which is all those with state "qw" and "hqw".
qstat -s h shows hold jobs, which is all those with state "hqw".
I want to be able to see all jobs with state "qw" only and NOT state "hqw". The man pages seem to suggest it isn't possible, but I want to be sure I didn't miss something. It would be REALLY useful and it's really frustrating me that I can't make it work.
Other cluster users have a few thousand jobs on hold ("hqw") and only a handful actually in the queue waiting to run ("qw"). I want to see quickly and easily the stuff that is not on hold so I can see where my jobs are in the queue. It's a pain to have to show everything and then scroll back up to find the relevant part of the output.

So I figured out a way to show what I want by piping the output of qstat into grep:
qstat -u "*" | grep " qw"
(Note that I need to search for " qw" not just "qw" or it will return the "hqw" states as well.)
But I'd still love to know if it's possible using qstat options only.
