5. List designated files and count the number of designated files

(1) View the number of files in the current directory (including files in subdirectories) Note: R stands for subdirectories

ls -lR|grep "^-"| wc -l

(2)# View the number of files in the current directory (excluding files in subdirectories)

ls -l|grep "^-"| wc -l

(3)# View the number of folder directories in the current directory (excluding directories in subdirectories), the same as above, if you need to view subdirectories, add R

ls -l|grep "^d"| wc -l

(4) Count the number of all files in all directories beginning with "20161124"

ls -lR 20161124*/|grep "^-"| wc -l

grep "^d" means directory, "^-" means file
