working on a command line is sometimes hard because you can get lost from all the changing for directories. well, if you are like me and ever get confused where you are, you can run the pwd command in linux and it will show you where your are currently on. because UNIX is a multisuer sytem, each user is given a separate workspace ro home directory do do his work. whe nyou log on, you are attached to your home directory. Because every suser is in his home directory, we don't step on each other. You can idedtify your current location with this command:

pwd

pwd is to get the current working directory.
