I don't use /bin/sh on a regular basis (bash, for better or worse) so I can't help you. >From a security standpoint, I'm more wondering what makes you so worried that someone will break in? Would some suggestions from the community about securing your system be helpful? (I'm no security guru so don't 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, Kevin
