Run make all in the project directory.

It will produce an executable called je2fs in the bin/ directory.

First create an image file for the disk with 512 blocks of size 1024 bytes.

dd if=/dev/zero of=disk.img bs=1024 count=512

Format the disk with ext2 file system using mke2fs.

mke2fs -t ext2 -b 2048 -N 64 disk.img

Program is going to work with the disk.img file you created. In order to monitor the filesystem you can mount it to a directory.

sudo mount -o loop disk.img fs-root/

./je2fs disk.img mkdir </abs/path/to/dirname>

./je2fs disk.img rmdir </abs/path/to/directory>

./je2fs disk.img rm </abs/path/to/file>
