Deleting history
 

Hi,
when i've execute some commands, those commands will be saved in history. if i type "hostory", it will display all the command that i've entered.
how do i clear this history. i dont want anyone (which could loged using the account that i used) to read the history.
thanks.

Type history -c

next time use command --help to know this. we are both newbies , but it's simple.
