Maybe it's time to send a feature request to a terminal emulator of your choice to implement it. (I remember xterm's maintainer was not against.) clear of ncurses emmits it: $ clear | hexdump -C 00000000 1b 5b 48 1b 5b 32 4a 1b 5b 33 4a |.[H.[2J.[3J| 0000000b Naturaly it should also extend to altearnative screens. As the purpose of the sequence is to erase all data for security reasons. -- Petr
