What is the Linux tree command, and how is it used?

Tree command help to list out the contents of directories in a tree-like format. Tree command provides tree diagram in-depth listing files.

Most commonly use tree commands in writing documentation, and secondly, we use tree commands to understand project directory structure.

If you use Linux and you think tree command is not your help. Because I have UI to understand every directory. that time, you're mistaken.

Most of the time app or project is very big. Because of many files, folders, or directories in the app, you do not observe and understand what happens in the app., which folder and file whats thing store and secondly, where store my custom components huge directories and folders.

You also face the same problem. Then you are right place. You understand the tree command concept by example.

The most common example. When I build  React.js open-source admin dashboard, I create many custom components and directories for my app., like header, footer, nav, and card directories, to separate every custom component and sass file.

This structure, I understand. But this is an open-source project. When I write documentation for the open-source react dashboard on GitHub. Then I manually design an image to tell others which folder to have a header component you change and where is asset folder is.

This folder or directories structure do not understand
This folder or directories structure do not understand

Right now, I just run the tree command to design a simple tree structure in my command terminal and use it in your documentation.
