Duh! RTFM - man echo (pdf, cuz I haven't quite figured out how got system pages yet):

echo '\033[2J\033[H'

works fine. The advantage of the c program is it doesn't put a newline after the escape sequences...

Is it possible to use echo to send a vt-100 escape sequence in v6/v7/sysvr2?

I can write a c program to clear the screen and go home in sysvr2:

#define ASCII_ESC 27
main()
{
printf( "%c[2J", ASCII_ESC );
printf( "%c[H", ASCII_ESC );
}

and it works fine. I can type the escape sequences in as well, but I'd just as soon write a shell script with an echo '[[2J;[[H' or something similar without having to compile a clear command. Is it possible and what do I need to know :)?.

Thanks,

Will
