/ * *
* perform statistics on files in the directory (including number of files and total number of lines)
*
* 1. When skipping files:
* matching rules only start at the file name, and matching rules are limited to the beginning.
* 2. Skip the comment line in the file:
The rule for * matches only from the head of the comment paragraph, and if there are // and * and lines beginning with # and /* and empty lines are skipped. So similar
