shell- An environment in which the following commands will be executed. The shell will not quit unless the exit command is executed. The shell shows a different command prompt (one that does not include $ and >).
tree - Make a directory named Dir0. The working directory will then be changed to Dir0. Create three empty text files, t1.txt, t2.txt, and t3.txt, as well as one empty directory called Dir1 within it.
list - Clear the terminal screen and output a detailed list of the current directory's contents to the terminal and t1.txt. Finally, it will rename the text file to tree.txt.
exit - Print a list of the previous four commands to the terminal, as well as a full list of the current directory's contents. Finally, wait for the user to press the "return" key to end the shell and return control to the actual shell software on your system.
