Round 1: Online Assignment

In this round, I had to design a Memory File System with various functionalities like:-

• mkdir: Create a new directory.
• cd: Changes the current directory. Support navigating to the parent directory using .., moving to the root directory using /, and navigating to a specified absolute path. Anything that you can do in a normal terminal. Since there is no user-level implementation, ~ and / should take you to root.
• ls: List the contents of the current directory or a specified directory.
• grep: Search for a specified pattern in a file. PS: It’s a bonus
• cat: Display the contents of a file.
• touch: Create a new empty file.
• echo: Write text to a file. ex – echo ‘I am “Finding” difficult to write this to file’ > file.txt
• mv: Move a file or directory to another location.
• cp: Copy a file or directory to another location.
• rm: Remove a file or directory.

This was an off-campus opportunity.
