Quick Directory Tree Creation: A Guide to Using the Ubuntu `tree` Command

Tree is a tool for visualizing directory structures in Ubuntu, which can intuitively display file hierarchies and is suitable for understanding project organization. To install it, first execute `sudo apt update`, then use `sudo apt install tree`. Basic usage: Simply enter `tree` to view the current directory's tree structure. Common parameters: - `-d` only shows directories; - `-L N` (where N is a number) controls the display depth (e.g., `tree -L 2`); - `-f` shows full paths; - `-F` distinguishes file types (directories are appended with `/`); - `-a` shows hidden files; - `-h` displays file sizes (in K/M/G). Advanced usage: Output to a file (`tree > dir.txt`) or combine with `find` to view system directories (e.g., `find /usr/share | tree -L 1`). By combining parameters, you can flexibly control the output and improve file management efficiency.
