Xterm is an X-client program working under the X-windows systemXterm 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 provides a command line interface into a UNIX system Xterm is the preferred command line interface because it is distributed with all X-windows systemXterm is the preferred command line interface because it is distributed with all X-windows system
