What does the tree command display?

The tree command displays the directory structure of a specified path in a hierarchical, tree-like format. Here’s what it typically shows:

Key Outputs:

1. Directories: Each directory is represented as a node in the tree, with indentation indicating its level in the hierarchy.

2. Files: Files within each directory are listed under their respective directories.

3. Hierarchy: The structure visually represents the parent-child relationships between directories and files, making it easy to see how they are organized.

4. Depth Control: You can limit how many levels of the directory structure are displayed using options like -L.

5. Hidden Files: If you use the -a option, it will also display hidden files (those starting with a dot).

Example Output:

Running tree in a directory might produce output like this:

.
├── dir1
│   ├── file1.txt
│   └── file2.txt
├── dir2
│   └── file3.txt
└── dir3
    └── dir4
        └── file4.txt

This output shows the current directory (.) and its subdirectories (dir1, dir2, dir3), along with the files contained within them.
