Supplemental Note: The function of the RGREP directive is similar to the GREP directive, which finds the file with the specified template style, and if the content of a file is found to fit the specified template style, the preset rgrep instruction displays the column that contains the template style.

Parameters：

-C calculates the number of columns that conform to the template style.
-D debug mode, which lists only the directory listings for the instruction search and does not read the file contents.

-H specifically marks the string that conforms to the template style.
-h lists only the strings that conform to the template style, not the contents of the entire column.
