tree (Unix)

Tree is a program available for Unix and Unix-like systems. tree is a recursive directory listing program that produces a depth-indented listing of files.

With no arguments, tree lists the files in the current directory. When directory arguments are given, tree lists all the files and/or directories found in the given directories each in turn. Upon completion of listing all files/directories found, tree returns the total number of files and/or directories listed.
