is there an easy way to `du -s' a tree and ignore the size of the directories themselves?
if, e.g., i have one deep directory tree with a long history of modifications, and another directory tree created from a `cp -a' of the first, their `du -sb' results are likely to be somewhat different. i can get this result with something like `find -not -type d -print0|xargs -r0 stat -c %s|paste -sd+|bc', but a simpler solution would be nice. -- Aaron Davies adavie...@me.com
