Easiest

$ make bang!

$ make superclean!

Bierman file (fsLowDriver.c):

$ make clean

$ make runLow

Our File (fsdriver3.c):

$ make clean

$ make run

hexdump (hexdump.c):

First (make runLow) || (make run)

$ make cleanHex

$ make runHexDump

functions:

(create a directory named 'foo' under the directory 'root')

Filesystem_Prompt$ mkdir foo root

(create a file named 'foo' under the directory 'root')

Filesystem_Prompt$ touch foo root

(list all directories under 'root')

Filesystem_Prompt$ ld root

(remove a file named 'foo' under the directory 'root')\n

Filesystem_Prompt$ rm foo root

(copy file 'foo' as 'blah' from directory 'hello' to directory 'world')

Filesystem_Prompt$ cp foo hello blah world

(move file 'foo' as 'blah' from directory 'hello' to directory 'world')

Filesystem_Prompt$ mv foo hello blah world

(set meta data category 'author' to name 'foo' 'bar' in file 'hello' in directory 'world')

Filesystem_Prompt$ set hello world author foo bar

(copy actual file '/my/local/path/on/my/computer.txt' to project directory 'root' as 'foo') --> try relative and full path

Filesystem_Prompt$ special1 /my/local/path/on/my/computer.txt foo root

(copy file 'foo' in directory 'bar' into '/my/local/path/on/my/computer/') --> try relative and full path

Filesystem_Prompt$ special2 foo bar /my/local/path/on/my/computer/
