This is a basic implementation of a filesystem and can be ported to raspberry pi 4. The end product contains a shell, a file system, and a virtual disk. The shell allows users to perform operations on the filesystem while the filesystem take operations specified by the user and perform them on the virtual disk. Within the filesystems, superblock, bit map, and iNode blacks contain metadata while data blocks contain the file and directory data.
Here is the list of available commands:
help display the file ls list files in current directory cd change directory make xxx create file mkdir xxx create directory rmf xxx remove file rmd xxx remove directory q quit silulation
dpd dump disk dpbm dump bit map blocks and iNodes dpi x dump block #x in iNodes table dpbl x dump block #x in data blocks dpbld x dump block #x (directory data) in data blocks
