List all directories recursively in a tree format

Question

I want to simulate a tree command using Shell Script that displays all the directories recursively in this format:

.
|-- Lorem
|-- Lorem
|-- Lor         


        

Answer 1

Modified base on the awk one from http://www.unix.com/shell-programming-scripting/50806-directory-tree.html

pwd;find . -type d -print 2>/dev/null|awk '!/\.$/ {for (i=1;i

Output looks more similar to tree:
