Suppose you type a command in terminal after Enter you will see a list which more than one page. Now you want to read the result from the beginning and you should scroll up. So if you put some commands before your last one its a bit difficult to scroll the the last one --at least for me -- So I need any key switch which show the screen from the last command.
ps: I want to screen show the last command by key switch. Is there any key switch like CTRL+ L which clear the screen. less command show the screen page by page.
