In this assignment you will write a command interpreter in Python or Java. The user types a command in response to a prompt that appears on the screen. When the command is entered, the command interpreter determines what the command means and executes the command. Your command interpreter should do the following. Display a prompt for the user. Read the user's input. Determine if the entered command is valid If it is valid, print a message that says the command is being executed and then re-display the prompt. If the command is not valid, display an appropriate error message and re-display the prompt. Continue until the user enters the command "QUIT". The valid commands will be LIST (lists contents of current directory) LIST path (lists contents of the directory identified by path) CHDIR path (changes current directory to the directory identified by path) RUN path/filename (executes an executable file in path) REMOVE path/filename RENAME old new (renames the file or directory name old to new) HELP (displays all valid commands and what they do) QUIT (terminates the program)
