Part-2
For part-2 this is how moved all the animals into the correct place. First, be sure that you installed the tree command using "sudo apt install tree" so that you can access your files with it.
1. For moving the animals into current pens, I used the rm commands to delete the files in the incorrect pens and used the touch command to create the correct files in the terminal.

2.Then, I renamed some of the files in the folders to give them the correct animal name using the mv command.

3.I also renamed the b1g_katz to big-cats pen using the mv command.

4. I added missing animals into the pens by using the touch command to create new files.

5. Finally, I used the rm command to remove the tourist file form reptiles.
