Linux traverses the same file name and calculates the sum of all file sizes

1. In the database of the sub-table, there may be different directories, the same file name, and we want to calculate

What is the size of the same data file, the following 1024 of the same file name, the method of calculating its size.

3) Intercept File size column

4) Sum
