The prompt When your login procedure is completed you should see the system prompt. This indicates that the shell is running and is awaiting instructions from the user. The prompt can take many forms, and you can change it later on if you want to. This number will represent the number of a command, and can be used to recall commands already issued. It may also display the name of machine or system that you are logged onto.
Some users prefer to have the name of the current working directory displayed in their prompt.
Changing your password Users will be assigned their username and initial password by the unix system administrator. You are advised to change the initial password to one that you will find easy to remember. Logging out When you have finished your unix session you must log out from the system. You should always wait for the message confirming that you have logged out. If this happens simply give the logout command again.
