File System Implementation

see details in README.txt

Compilation Instructions

1. To compile the program, use the following commands:

   make clean    # Clean up any previous build
   make         # Compile the program
   

Execution Instructions

1. The program can be executed using the following command format:

   ./filesys -s <test_file>
   

2. Example command:

   ./filesys -s test_disk_full.txt
   

Important Notes

1. Before running each test file, it's crucial to: a. First clean up resources with: make clean b. Recompile with: make c. Then run the test file

2. This ensures each test starts with a fresh state and prevents any interference from previous test runs.

Example Test Sequence

To run multiple test files:

make clean
make
./filesys -s test_basic.txt

make clean
make
./filesys -s test_file_size.txt

make clean
make
./filesys -s test_dir_full.txt

make clean
make
./filesys -s test_disk_full.txt

Implementation Details

The file system implementation supports the following commands:

• mkdir: Create a new directory
• ls: List contents of current directory
• cd: Change current directory
• home: Return to root directory
• rmdir: Remove a directory
• create: Create a new file
• append: Append data to a file
• cat: Display contents of a file
• tail: Display last 10 lines of a file
• rm: Remove a file
• stat: Display file/directory information

All features have been implemented as per the specifications.

Known Issues

No known issues. All features are working as expected.

File Structure

The implementation is contained in two main files:

1. FileSys.h - Header file containing class definitions
2. FileSys.cpp - Implementation file containing all the file system functionality
