-d] [cols [lines]]
Toggle the window width between 80 and 132 columns, or set it to cols columns if an argument is specified. This requires a capable terminal and the termcap entries ‘Z0’ and ‘Z1’. See the
termcap command (see Termcap), for more information.
You can also specify a height if you want to
change both values. The
-w option tells screen to leave
the display size unchanged and just set the window size,
-d vice versa.
-d] [lines [cols]]
Set the display height to a specified number of lines. When no argument is given it toggles between 24 and 42 lines display.
