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

Modifying sputnick's answer to get closer to your original format (which I prefer):

find ./ -type d -print | sed -e 's;[^/]*/; /;g;s;/ ;    ;g;s;^ /$;.;;s; /;|-- ;g'

The only difference now is the last line doesn't start with a backtick:

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

with awk

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