HW2

In this exercise, you will restructure one file tree into another, using any of the Unix utilities shown in class (cp, mv, mkdir, rmdir, touch, and ls). Submit the exact sequence of bash commands used. Remember to use tab-completion to make using the command-line easier.

Directions

ssh into eustis:

ssh NID@eustis.eecs.ucf.edu

Download the file tree for the exercise:

wget -O ~/hw2.tar 'https://www.cs.ucf.edu/~pappas/teaching/cop3402/fal2026/files/hw2.tar'

Extract the file tree:

tar -C ~/ -xvf ~/hw2.tar

Enter the file tree:

cd ~/hw2

The file tree should look like the following when typing tree ~/hw2

.
├── drivers
├── fs
│   └── ext2
│       └── acl.c
├── hid
│   ├── bpf
│   │   └── Makefile
│   ├── i2c-hid
│   │   └── Makefile
│   └── usbhid
│       └── Makefile
├── Makefile
└── net
    └── ethernet

Now find a sequence of commands that restructures the tree into the following one:

.
├── drivers
│   ├── hid
│   │   ├── bpf
│   │   │   └── Makefile
│   │   ├── i2c-hid
│   │   │   └── Makefile
│   │   └── usbhid
│   │       └── Makefile
│   └── Makefile
├── fs
│   └── ext4
│       └── acl.c
├── Makefile
├── net
└── sound

Submit the sequence of bash commands as your homework.

Important notes

New files may be files or directories.
There are many ways (sequences of commands) to solve the problem.
The entries (children) in a directory are unordered. For instance, if fs/ is before or after drivers/ that is okay. The file system guarantees tree structure, i.e., parent-child relationships, but not ordering of entries in a directory.
If you need to start over, go back home, move your prior hw2 version away, and unpack the example again:
```
cd ~
rm -r ~/hw2
tar -C ~/ -xvf ~/hw2.tar
cd ~/hw2
```
You only need these commands to perform the changes
