FUSE Filesystem

A basic file system written in C using FUSE

About fuse

From the official repository

FUSE (Filesystem in Userspace) is an interface for userspace programs to export a filesystem to the Linux kernel. The FUSE project consists of two components: the fuse kernel module and the libfuse userspace library. libfuse provides the reference implementation for communicating with the FUSE kernel module.

Basically Fuse allows us to call our own functions instead of using the default kernel functions when a system call is used. That is incoming requests from the kernel are passed to the main program using callbacks. Where we can define our own functions to handle them.

Installing FUSE

For Ubuntu

$ sudo apt-get install libfuse-dev

Using the Filesystem

Clone this repository

$ git clone https://github.com/Aveek-Saha/FUSE-Filesystem.git FS

cd into the directory and create a mount point

$ cd FS
$ mkdir mountpoint

Complile and run FS.c

$ gcc FS.c -o FS `pkg-config fuse --cflags --libs`
$ ./ FS - f path/ to/ mountpoint

Change your current working directory to mountpoint and use the file system.
