Here are examples of job requirements that use job resource expressions:
% qbsub --requirements "job.type in host.jobtypes" ls
% qbsub --requirements "job.user eq host.name" ls
Here are some examples of job requirements that include property expressions:
% qbsub --requirements "host.os eq linux" ls
% qbsub --requirements "host.name eq host01" ls
% qbsub --requirements "host.flag.remove_logs host.group has host05" ls
% qbsub --requirements "(host.os == 'winnt') and host.processor_speed >= 100" ls
