If you need to do anything on a list of files/dirs, but they are not in the same place, or not easily filterable (e.g., all sub directories "/Fillion" but not the ones that start with "Nathan") you can use find to prefilter everything, then hand it over via xargs (if you want all to be handled by one instance of the action program) or with "-exec" (if you want each instance to be handled by a separate instance by the action program). Also check out "find tutorial" articles like this one: http://www.grymoire.com/Unix/Find.html http://www.grymoire.com/Unix/Find.html (e.g., did you know you can filter by size?)
