4 directories, 8 files

ls -R | grep ":" | sed -e 's/://' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'

which gives output like this:

   |-cmd
   |---api
   |-public

If you want to copy this, simply add "| pbcopy" to the command above and everything it outputs will be saved in your Clipboard and you can then paste into Email, MS-Word documents or wherever you like.

ls -R | grep ":" | sed -e 's/://' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/' | pbcopy

add "| pbcopy" to all of these to copy the output to the Clipboard.
