The book Unix Power Tools dedicates all of chapter 9 to the find command.

For instance, you can see all of the files and directories in the AirBnB directory (and all of the directories recursively contained in there as well):

find /anvil/projects/tdm/data/airbnb/ -print

You can use the find command to find all of the files and directories in your current directory and in any subdirectories and sub-sub-directories, etc. (Be sure to think about where you are using this, because if there are millions of files and directories in your current directory, find will try to print them all!)

find . -print

For instance, you could navigate to the AirBnb data directory and then print all of the files and directories inside. (This is equivalent to the earlier example.)

If you want to see all of the ls -la information about each file and directory in the current directory, you can run ls -la on each line of find . -print as follows:

To find all files in the current directory (or any subdirectories) that have the file extension ".adoc" we can run:

or, similarly, we could find all "pdf" files in the current directory (or any subdirectories)
