Sometimes you need to know the combined size of a given files that are combined with other files in the same dir, either by their extension or by some other property.

This example is based on file extension, but can be adapted to any other results you like find to return:

find . -name "mysql-bin.*.1" -size +1000000c -print0 | du -hc --files0-from=- | awk 'END{print $1}'
