Step1

• use make file to make execution file
• the BDS command is

./BDS <disk file name> <cylinders> <sectors> <track-to-track delay time> <port>

• the BDC execution command is (so as the BDC_random)

./BDC <server address> <BDS port>

• In BDC, the commands are as below

I
W <cylinder num> <sector num> <data length> data
R <cylinder num> <sector num>
E

Step2

• use makefile to generate the execution file
• the BDS execution command is

./BDS <disk file name> <cylinders> <sectors> <track-to-track delay time> <port>

• the FS execution command is

./FS <server address> <BDS port> <FS port>

• the FC execution command is

./FC <server address> <BDS port>

• the commands in the file system are as below

f
mk f
mkdir d
rm f
cd path
rmdir d
ls
cat f
w f l data
i f pos l data
d f pos l
e

Step3

• the command to execute BDS, FS, FC is the same as those in step2
• the command in file system is also the same as those in step3
• when the client connect to the FS, the first command is to enter the user or create user or delete user

C <user name> <user password> // create a user
E <user name> <user password> // enter a user
D <user name> <user password> // delete a user

shift // shift from current directory to shared directory or from   
         shared directory to user root 

The concrete operations are shown in the report.
