How does shell read all files in a folder?

The find command in shell can be used to read all files in a folder. For example, to read all files in a folder named “folder”, you can use the following command:

find folder -type f

This will list all the files in the folder directory and print out their paths. To print out the contents of all the files in the folder together, you can use the following command:

find folder -type f -exec cat {} \;

This will print the contents of all files in the folder directory.
