Since I switched from macOS to Linux, I keep discovering new CLI tools and re-discovering some old ones. Here is one of the forgotten ones: tree.
tree
.
├── config
│ └── filebeat
│ └── filebeat.yml
├── docker-compose.yml
└── README.md
It’s very simple but super convenient. It allows users to see a complete structure of any directory without checking each sub-folder manually, and it’s output can be customized. For instance, we can add -h argument in order to show the size of each file in the output:
tree -h
