Support the cat command. This should print out the contents of the specified file cat <filename>.

Support the redirect to file >> command. This will allow the user to send output to a specified file so it doesn't flow the shell.

Currently, the whole text area can be deleted. To act like a real shell, the user should only be allowed to delete the current command and command line arguments.

Support the tree command which will print out a tree structure of the current directory, current files, sub-directories, and sub-files.

Support the ls command. This should print out all of the items in the current directory or an optional specified directory ls <directory>.

Create a basic GUI that just has a text area for the user to type in. Also, package this as a jar so that when double-clicked, it opens the GUI.

It would be nice to include output colors for different things:

• Files
• Folders
• Background
• Font

Add a command that notifies to the user that their input is invalid.

Support the exit command. This should exit the shell.

Support the pwd command. This should print out the current working directory of the shell.

It would be nice to have a monospaced font in the shell.

Support the cd command. This will allow the shell to change its current directory. Some optional parameters are:

• Full path to directory - cd <full path>
• Path to parent directory - cd ..
• Path to child directory - cd <child>

Parse the last line of the text area as the user input and print it back out to the text area. Enter should be used as indicating a "command" and all input on the same line before enter should be spit back out.
