If you aren’t familiar with the Tree command in Linux, you should be. You can read about it here. Tree has been around for what seems like forever, and I’ve been using it for as long as I’ve been using Linux. With that said, I didn’t really know all that much about it until recently. The extent of my usage has always been something like this: $ tree -L 3 and that’s it.

Like most other Linux tools, there is much more to Tree than what I know. Take a look at the following command:

$ tree -LpDugC 2 -H .  > index.html 

This will create an index.html file that has a listing of everything in the dir in HTML form.

Anyway, you can install tree on Linux, Mac, and even Windows. There really wasn’t a huge point to this post — it’s just a reminder that your tools can do a lot more than what you’re probably already using them for. It pays to read the documentation.
