This article introduces the knowledge of "how to use the tree command to display the file directory structure in a tree structure under linux". In the operation of the actual case, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. There is no tree command by default in the ubuntu system, and you need to install it. You can install the tree command tool sudo apt-get install tree with the following command.

2. First of all, the editor will talk about how to use the tree command. In fact, there is a very simple way to view the help on tree directly. Enter the following command to view the help information about the tree command tree-- help

3. Let's talk about how to use tree. The easiest way to use it is to enter the tree command directly, and it will automatically list the files and folders of the current directory in a tree form. Without any parameters, it will automatically list all the files and directories under the current directory.

4. Let's talk about how to view different levels of subdirectories and files using the "tree-L 1" command, only the current first-level directories and files use the "tree-L2" command, only the current second-level directories and files use the "tree-LN" command, and only the current N-level directories and files

5. What I said above is just to show the current results, but in many cases, we want to save the directory structure information, reserve it ourselves or send it to others. Let's talk about how to achieve this goal.

Use the following command to save the directory structure information of the second-level subdirectory of the current file to the / home/xyh/tree.txt file

Command: tree-L 2 > / home/xyh/tree.txt

6. Let's open the / home/xyh/tree.txt file to see if the saved result is the same as that shown by the command we used before. We can see that the saved result of the file is the input result using the command "tree-L 2".
