Found this very useful command to recursively list a directory structure in a graphical format in Mac OS X:
find . -print | sed -e 's;[^/]*/;|____;g;s;____|; |;g'
It is the equivalent of the tree command in Linux and Windows.
An simple example of the output is below:
|____Test1 (1080P) | |____Test1 (1080P).mkv |____Test2 (1080P) | |____Test2 (1080P).mkv |____Test3 (1080P) | |____Test3 (1080P).mkv |____Test4 (1080P) | |____Test4 (1080P).mkv
A very useful command on Mac OS X.
