You could set the history file count to zero, and then reset it to the proper value. You could, from the shell, type $SHELL;clear And when done, hit control-d, which will erase history and clear the screen. I usually open a new tab, and when done, I close the tab.

If you want to clear the terminal's buffer, that depends on whether your terminal has that capability. -- Chris F.A.

It works for me. For clearing history, try # history -c I found that with a google search. -Mike

It does not clear the history. history -c is supposed to clear the history, in bash. So you want clear;history -c you can make that an alias alias clrhist='clear;history -c' and put it into .bashrc
