Heh, that sounds more like a ugly hack than a solution if you ask me.

No, it's not meant to clear the buffer. If you need to clear the
buffer, just cat a really, really long file.

Hello,
For some reason, I thought little about the "clear" command today..
Let's say a privileged user (root) logs on, edit a sensitive file (e.g,
a file containing a password, running vipw, etc) .. then runs clear and
logout. Then anyone can press the scroll-lock command, scroll back up
and read the sensitive information.. Isn't "clear" ment to clear the
backbuffer instead of printing a full screen of returns? If it does, I'm
not sure how that would effect a user running "clear" on a pty (telnet,
sshd, screen, etc) ..
Best regards,
Jesper Wallin
