Logging out

When you wish to finish using UNIX - known as logging out - there are two things you need to do.

Firstly, in each command window you should type ctrl-D on a line by itself. Sometimes the system will be set up so that ctrl-D fails to work, in which case you should type exit instead.

Secondly, you must close down the window manager by following the menu choices to Logout. The machine will respond by giving you a prompt so that the next user can log in.
