What is xterm? • Xterm is an X-client program working under the X-windows system – An X-windows client is any program running under the X-window graphical user interface system
• xterm provides a command line interface into a UNIX system • Xterm is the preferred command line interface because it is distributed with all X-windows system 4

Mouse Button Issues • X-window system assume a 3-button mouse system • Behavior of each of the buttons can be reconfigured by the user – In general, we will use the defaults
• In emulating systems that have less than 3 buttons – 3rd button may be simulated by clicking two buttons simultaneously (2-button system) – Two other buttons may be simulated by clicking button while holding different keys down (1-button system)

Other issues • These actions of cutting and pasting works for most X-client programs under UNIX • Stick to xterm as your main port into UNIX and you will have little problems migrating from one UNIX platform to another
