Default Keybindings

  • C-a c
  • C-a C-c


  • screen [-opts] [n] [cmd [args]]


Establish a new window. The flow-control command-line options (-f, -fn and -fa), title (a.k.a.) option (-t), login options (-l and -ln) , terminal type option (-T <term>), the all-capability-flag (-a) and scrollback option (-h <num>) may be specified with each command. The option (-M) turns monitoring on for this window. The option (-L) turns output logging on for this window. If an optional number n in the range 0..MAXWIN-1 is given, the window number n is assigned to the newly created window (or, if this number is already in use, the next available number). If a command is specified after screen, this command (with the given arguments) is started in the window; otherwise, a shell is created.

Note that, unlike previous versions of screen, no additional default window is created when screen commands are included in your .screenrc file. When the initialization is completed, screen switches to the last window specified in your .screenrc file or, if none, opens a default window #0.

screen has built in some functionality of cu and telnet. See also chapter Window Types.


If your ”.screenrc” contains the lines

# example for .screenrc:
screen 1
screen -fn -t foobar -L 2 telnet foobar

screen creates a shell window (in window #1) and a window with a TELNET connection to the machine “foobar” (with no flow-control using the title “foobar” in window #2) and will write a logfile (“screenlog.2”) of the telnet session.
