It is normally a good sign! By default, when using command line executeworkflow script, the output of the workflow will be written to a directory named after the workflow file. So if you executed:
executeworkflow.sh my_workflow.xml
you should find a directory my_workflow.xml_output, containing at least progressReport.xml, and a directory structure for the workflow output.
Note that you can modify the output options, run with option -help for more information.
