tree

Tree is a command line tool that displays the structure of directories and files in a tree-like format on Unix-like operating systems. It allows users to visualize the hierarchical organization of files and directories in a clear and structured manner.

1. Tree is a simple yet powerful utility that helps users explore and understand directory structures.
2. Upon execution, tree starts from the current directory and displays the directory structure recursively.
3. By default, tree displays directories before files, with an indentation indicating the hierarchy.
4. The output of tree includes the names of directories and files, along with various metadata such as size and permissions.
5. Users can customize the output using various command line options to filter or exclude specific files or directories.
6. Tree supports a variety of options, like displaying only directories or files, showing hidden files, or limiting the depth of the tree.
7. Users can also control the level of indentation, include file sizes, show file permissions, or print the tree in color.
8. Tree is commonly used for directory navigation, file discovery, and obtaining an overview of large directory structures.
9. It is particularly useful for developers, sysadmins, and other professionals dealing with a vast number of files and directories.
10. Tree is open source and widely available, offering compatibility across various Unix-like systems including Linux and macOS.
