Ah ok. "reset" is the right one to use here. But, what you really need is cup mode. Although, they are not supported in some terminal types. Cup mode is not very well documented so you might find a hard time getting details on them. Here is a short tutorial on that. On Unix Terminals, there is a feature to open an Alternate Screen which is essentially what cup mode is. To try it, you can do the following, $ echo -en "\033[?1049h"; clear; echo "abcd"; sleep 5; echo -en "\033[?1049l" The above commands create an alternate screen, stay on it for 5 seconds and exit to the original screen. The first echo line is to enter cup mode and the last echo line is to exit cup mode. And, To check whether a terminal supports cup mode, you can do the following, $ infocmp vt100 | grep smcup #vt100 doesn't support cup $ infocmp xterm | grep smcup #xterm supports cup sgr0=\E(B\E[m, smacs=\E(0, smam=\E[?7h, smcup=\E[?1049h, -- 0 _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
