Describe Why This Is Awesome

Why is this awesome?

The main reasons are as follows.

  • This CLI tool was a tool that I couldn't find anywhere else!👍
• Easy to install.
• Directory can be specified.
• Many options!

Furthermore, it was also featured in AWS open source newsletter, #189 !

Finally, I will briefly introduce what happens when I run this CLI tool.

$ stree test-bucket
test-bucket
├── chil1
│   └── chilchil1_1
│       ├── before.png
│       └── github.png
├── chil2
└── gommand.png

3 directories, 3 files
$ stree test-bucket/chil1
test-bucket
└── chil1
    └── chilchil1_1
        ├── before.png
        └── github.png

@ddddddO Thank you for sharing here!

Thanks for your work on gtree which has inspired stree.

I will look at both projects to see how I may learn from them to improve my own aws-org-tree.
