screen is a much under utilised program, which provides the following functionality:
  • Remote terminal session management (detaching or sharing terminal sessions)
  • unlimited windows (unlike the hardcoded number of Linux virtual consoles)
  • scrollback buffer (not limited to video memory like Linux virtual consoles)
  • copy/paste between windows
  • notification of either activity or inactivity in a window
  • split terminal (horizontally and vertically) into multiple regions
  • locking other users out of terminal

See also the byobu screen config manager. See also the reptyr as another way to reattach programs to a terminal. Note for nested screen sessions, use "Ctrl+a a" to send commands to the inner screen, and the standard "Ctrl+a" to send commands to the outer screen.
