I don't use /bin/sh on a regular basis (bash, for better or worse) so I
can't help you.

ask me . . . 8-< )
Also, why are you worried about them seeing what commands you've been
running? My first thought is that at the point a malicious someone has
broken into your system, you have (much) bigger things to worry about.
But, to dumbly answer your question, see if sh looks for ~/.logout. If
it does, have it remove ~/.history and clear the screen. Or, if the
order of that doesn't work (if .logout is read /before/ .history is
written), 'chmod 000 .history'.
Best of luck,
