Seeing the forest with tree
In Full View
The tree command can provide a clear view of all your files and directories and offers a few advantages over the usual ls command.
tree command  is a tool that I'd overlooked until recently. After trying it for several weeks, however, I am starting to prefer its tree-like display of directories and files to the plain lists generated by
Part of the reason is that, in these GUI-oriented days, even a directory tree made with ASCII characters is more comfortable than no structural display at all. The functional differences between
ls are minimal. The two commands share a few options, such as
-a for displaying all files, and even when the options are different, the functionality remains similar. The largest exception I have noticed is that
ls offers an option for the number of columns in which to display results; the
tree display makes a single column unavoidable.
You have to look closely to see the differences, but
tree is consistently more versatile, starting with, unlike
ls, recursion. By default,
tree displays all files in all subdirectories.
