+## Change struct
+
+You need to rearrange the file structure that you created earlier in the "file-struct" exercise.
+Here is an example of how to move, rename, copy and delete a file or repo:
+
+**_Copy_**
+
+```console
+cp `file to copy` `path of destination`
+cp -r `repo to copy` `path of destination`
+```
+
+**_Move or Rename_**
+
+```console
+User-> mv `file to move` `path of destination`
+User-> mv -r `repo to move` `path of destination`
+User-> ls
+text.txt old_repo
+User-> mv text.txt new_text.txt
+User-> mv old_repo new_repo
+User-> ls
+new_text.txt old_repo
+```
+
+**_Delete_**
+
+```console
+User-> rm `file to remove`
+User-> rm -r `repo to remove`
+```
+
+### Instructions
+
+Use those commands to create the following file structure:
+
+    - Copy the `struct` repo that you created and change its name to `new_struct`.
+    - Create the `0_to_3` and `6_to_9` folders.
+    - Move the folder `0, 1, 2 and 3` inside the `0_to_3` folder.
+    - Move the folder `6, 7, 8 and 9` inside the `6_to_9` folder.
+    - Remove the folder `5`.
+    - Rename the folder `10`, to `new_folder`
+    - Copy the folder `1` inside the folder `8`
+
+In this exercise you wil use the command `tree` to see the file structure as in the example bellow. `tree` is a recursive directory listing program that produces a depth-indented listing of files. With no arguments, `tree` lists the files in the current directory.
+
+```console
+User-> tree new-struct/
+new-struct/
+├── 0_to_3
+│   ├── 0
+│   ├── 1
+│   ├── 2
+│   └── 3
+│       └── text.txt
+├── 4
+│   └── text2.txt
+├── 6_to_9
+│   ├── 6
+│   ├── 7
+│   ├── 8
+│   └── 9
+└── A
+    └── text3.txt
+```
+
+Once it is done, use the command below to create the file `done.tar` to be submitted.
+
+```console
+User-> tar -cf done.tar *
+User-> ls new-struct/
+0_to_3  4  6_to_9  A  done.tar
+```
+
+**Only `done.tar` should be submitted.**
+
+**Tips:**
+
+Use the command `man <name of the command>` to get more info on some command that you need to use.
