Tree

The tree "program/command" enables you to create an ASCII art diagram for the directory tree under a given folder.

Useful options

-d

List only directories, not files

-L #

List only # levels including the target directory

For example:

tree -d -L 6 FullUWwHybridGamma06/ > FullUWwHybridGamma06/dirTreeArt.dat

Makes a tree of directories only (-d) that is 6 levels deep and redirects the output from the terminal to a file. This gives the following output:

FullUWwHybridGamma06/
