Just edit the file ~/.bash_history.

Typing "history -d xxx" will delete a specified line. You then have to type "history -w" to make them permanent. It also removes them from the .bash_history file. The surest fire way is cYrus's answer.

Both answers a correct for fixing after the fact.

Simply put a {space} before any command in terminal will prevent it from being logged in the first place.

Remove all records: {space}history -c -w
