Re: [Condor-users] Marking child as DONE

Hi Nick,

Rather than setting 'executable = /bin/true' you could add to
the submit file 'hold = True'. The child jobs will then be submitted
and held and will not run unless you explicitly call
condor_release on them.

In a similar way you could set 'noop_job = True' for the child
jobs and the jobs will simply be marked as completed with a
return value of 0.
