Task 6: Create a new directory called "Test.Dir" using the mkdir command. After it is created, delete the directory by using the rmdir command. I Task 7: We now want to navigate to the directory logically one level above us, so we will use the change directory command, "cd ..". Now we want to move up another level, so we will run the command again. We then want to move back into the original directory, so we will use the cd command again, this time we will use the relative path, which starts with a ./ and then should be pointed to ust/[username)
