Assuming this is referring to the qsub utility that is specified by the POSIX standards (although few implementations provide the optional POSIX Batch Environment Services and Utilities features), wait won't work. The qsub utility submits a job to be executed on a remote server and returns as soon as the job is queued on that server. Normally, the server running the job will send mail to the submitter when the job completes.

There are a few ways to do what I think you're trying to do. One way is to periodically run a qstat command with operands being the job IDs that the calls to the qsub utility returned for the jobs they submitted. You would then have to parse the qstat output to determine when a job completes and at that point kick off another qsub to replace the completed job on that server.

Another way would be to have the last step executed by the job you submit with qsub be another qsub command that will queue a job on the server that submitted the original qsub and have that job kick of a replacement if work remains to be done.

qsub

QSUB(1) 						User Contributed Perl Documentation						   QSUB(1)

NAME

       qsub - submit a batch job in a familiar pbs format

SYNOPSIS

       qsub  [-a date_time]
	     [-A account_string]
	     [-b secs]
	     [-C directive_prefix]
	     [-e path]
	     [-I]
	     [-l resource_list]
	     [-m mail_options] [-M  user_list]
	     [-N name]
	     [-o path]
	     [-p priority]
	     [-q destination]
	     [-W additional_attributes]
	     [-h]
	     [script]

DESCRIPTION

       The qsub command displays information about nodes. It is aimed to be feature-compatible with PBS' qsub.

OPTIONS

       -a  Display information for all nodes. This is the default if no node name is specified.

       -I  Interactive execution.

       -j join
	   It is not necessary (currently also not possible) since stderr/stdout are always joined.

       -v [variable_list]
	   Exporting single variables via -v is not supported, since the entire login environment is exported by the default.

       -V  The -V option to export the current environment is not required since it is done by default.
