6.1. terminal

6.1.1. resize - set TERMCAP and terminal settings to current xterm window size

显示终端屏幕的尺寸

$ resize
COLUMNS=151;
LINES=46;
export COLUMNS LINES;		
			

设置终端屏幕的尺寸

eval `resize`
			

6.1.2. tset, reset - terminal initialization

tset -e ^? 设置Backspace删除前面一个字符
tset -k ^C 设置删除一行
			

建议使用stty替代tset
