[gradsusr] Getting date and run from filename

[Jennifer Adams]

Well, if your data set is not templated, the name of the data file will be in the output from 'q file' and 'q ctlinfo'. If you are templating, it's harder because the data file name contains the template strings, not the actual date strings. But maybe with the help of the 'q time' output you could piece it together.
