How to Compile & Execute

Requirements

• Compiler: gcc -std=c99 nameOfFile -o whatYouWantTheExecutableToBeNamed
• Dependencies: None needed to be downloaded

Compilation

make

This makes the whole executable for our Project 3.

Execution

./bin/shell fat32.img

This will run the shell program and give you access to every command we provide for a FAT32 image file. You cannot do "make run" because you won't be able to insert the image file.
