screen: Screen Command
6.2 Screen Command
==================
-- Command: screen [opts] [n] [cmd [args] | //GROUP]
('C-a c', 'C-a C-c')
Establish a new window. The flow-control options ('-f', '-fn' and
'-fa'), title 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.
If '//group' is supplied, a container-type window is created in
which other windows may be created inside it. Window

Window Types.
Thus, if your '.screenrc' contains the lines
# example for .screenrc:
screen 1
screen -fn -t foobar 2 -L 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. If you do not include any 'screen' commands in your
'.screenrc' file, then 'screen' defaults to creating a single shell
window, number zero. When the initialization is completed, 'screen'
switches to the last window specified in your .screenrc file or, if
none, it opens default window #0.
