i accidently typed my root password before typing 'su',
so, now anyone can see my commands history and know password....what should i do to delete it from history.
I definitely don't want to delete complete history as it contains some very important commands.

If using bash:

Code:

history -d number

where number is the position in the current history list.

it seems that root and normal user histories are different !
when i try to delete normal user terminal history by using command provided above,then it is deleted temporarily but when i close terminal and restart it and then browse history then that command again comes on same number.
How to delete it permanently ?
