Using this ghost shell, how can I make the script that unpack contents of each top$-$level ZIP archive in the current directory, one at a time into a new subdirectory named after the original archive. In the subdirectories, extract and identify each individual archives. These archives should be extracted into directories named after students username. Repeat for every student archive inside the current subdirectory, non$-$archive files should be ignored. After each individual archive has been extracted to a folder, the original archive file can be deleted. Repeat for every top$-$level ZIP archive in the current directory, once all top$-$level archives have been extracted, the script may exit.
