System Requirements

• macOS operating system
• Python
• FUSE for macOS (installable via Homebrew)
• GCC compiler
• Check unit testing framework (installable via Homebrew)

Installing Dependencies

On macOS, you can install the necessary dependencies using Homebrew:

brew install osxfuse
brew install check

Building the Project

Build the project using the following command:

make all

This will generate the following files:

• fuse: FUSE filesystem executable
• unittest-1: Unit test suite 1
• unittest-2: Unit test suite 2
• test.img: Test disk image 1
• test2.img: Test disk image 2

Running Tests

Run the unit tests:

./unittest-1
./unittest-2

Usage

1. Generate a disk image:

python gen-disk.py -q disk1.in test.img

2. Read disk image contents:

python read-img.py test.img

3. Mount the filesystem:

./fuse [mount_point] [disk_image_file]

Cleaning Up

Clean build files:

make clean

Notes

• Ensure you have appropriate permissions to mount the filesystem
• This filesystem is intended for educational and testing purposes only
