Time to learn about yet another cool little admin application that will change the way you think and work. screen is a full-screen window manager that multiplexes a physical terminal between several processes, typically interactive shells. Each virtual terminal provides the functions of the legendary DEC VT100 terminal.
Additionally, the utility has insert/delete line, support for multiple character sets, a scrollback history buffer for each virtual terminal, and a copy-and-paste mechanism that allows moving text regions between windows.
When screen is called, it creates a single window with a shell in it and then gets out of your way so that you can use the program as you normally would. Then, at any time, you can create new full-screen windows with other programs in them, including more shells, kill existing windows, view a list of windows, turn output logging on and off, copy & paste text between windows, view the scrollback history, switch between windows in whatever manner you wish, etc.
