In article Count Files in Directory in Linux we showed a simple method to count files in a single directory with
ls | wc -l. In order to count number of files in a directory and its subdirectories, we can use more sophisticated
Go to your folder and type:
$ find . -type f ./.gitignore ./booking.php ./file1.php ./README.md ./file3.php ./subfolder/.gitignore ./subfolder/README.md
This outputs all the files recursively in that folder.
.stands for the “starting point” of the search
-type ftells the find to find only files (not directories)
However, we wanted to know the number of files, not the list of files. For this we use the
wc -l to calculate number of lines of the input.
$ find . -type f | wc -l 7
This outputs a 7 which is correct.
