BACKGROUND: FILE SYSTEMS
In a computer, a file system (sometimes written filesystem) is the way in which files are named and where they are placed logically for storage and retrieval. The DOS, Windows, OS/2, Macintosh, and UNIX-based operating systems all have file systems in which files are placed somewhere in a hierarchical (tree) structure. A file is placed in a directory (folder in Windows) or subdirectory at the desired place in the tree structure.
The purpose of this assignment is to familiarize students with the linux file system and start writing programs which interact with the kernel using system calls. You are strongly urged to spend some time exploring the linux file system so you properly understand the hierarchical structure.
ASSIGNMENT STATEMENT
Create a linux shell (in other words, write a C/C++ program) that will recursively prompt for input from the user. The shell should prompt as
yourRollNumber-currentDirectoryName>
For instance if the current directory is /home/OS, the shell should prompt as:
B-12345-OS>
For example purpose, consider the following file structure, the current working directory is named as OS and it contains a file hogwarts.txt and two sub-directories called teachers (which has two files called dumbeldore.txt and snape.pdf) and students (which has a subdirectory called gryffindor which has a file called harry.vlc)
