I am trying to find a single specified file in a set of directories. The filename is currently selected, the directories are listed at the bottom of my text file as follows: [path:adirectory][path:anotherdirectory][path:yetanotherdirectory].

The paths are searched recursively (ie: subdirectories are searched as well), or alternatively I can allow globs in the paths like so: [path:C:\toplevel\projects\*\]

I've got searching the current document for [path:xxxx]. I've got the selected filename.
What I am having trouble with is searching the filesystem for the filename. I am trying to figure out how to use DirectoryListSet to do this, but I cannot see how it can be used alone without involving the GUI. I also tried to figure it out using File.list(), but cannot figure out how to specify a filter.
Any help I've found googling around has been in Java, not Beanshell, and since I'm not expert at either I cannot figure out how to translate the Java solutions into Beanshell.

Any help?
