bash: ls command to see list files in current directory all subdirectories

The ls command lists all the directories and files in the current directory that you are in. If you have subdirectories within the current directory and you want to know using the ls command what are the files within the subdirectories in a single execution you will need to make use of the -R option.

As you can see in the above example, we have two subdirectories Archive-2010-2020 and Archive-2020-2030 and both of them have files in them. Using the -R flag we are able to recursively list all files and directories in the current directory and all of its subdirectories.
