Section C. INTRODUCTION TO UNIX Logging In A terminal displaying the prompt login: is requesting your user name (this is the name assigned to you by the system administrator). What you type appears on the screen; this is called echoing. After you type in your user name, press [ENTER]. The next prompt is password: Enter the password assigned to you and press [ENTER]. Notice that as you type your password, the characters are not echoed to the screen; this is a security precaution against inquisitive eyes. Displayed next is the "message of the day"; important system information and notices such as system downtimes. Finally your default shell prompt will appear. This may often simply be a "%", indicative that the default shell is the C shell (csh), or a "$", which is the character used by the Bourne shell. Other systems may instead display the hostname of your computer or your login ID. Logging Out The are several ways of logging off the system at the end of your session (though not all ways will work in all shells): % exit % ^D note: the '^' means to hold down thekey then simultaneously press the "D" key) % logout
