My file system is set up like:/ftp/data/ProductGroup*/ProductType*/Year*/Day*/ActualProductFile*(*denotes directory names that change)I'd like to find out how much space is being used for 2011 products.  Something likedu -ks /ftp/data/*/*/2011However, I need the sum of all these directories - there are hundreds of them and I don't want to have to add them all up (too error prone!)Would anyone have a suggestion?
How can I get a total for space used by a group of subdirectories
