How to delete bash terminal history upto certain no. of commands

i want to delete some say 10 previous commands in bash shell!! what shud i do??

Why would you be wanting to cover your tracks like that? :tisk:

Try editing ~/.bash_history. If that doesn't work, IDK. I think there is a way to get bash to not add it to history at all, but I don't recall exactly how it's done. I stumbled upon it once by accident...

'should'.

Bash history is usually stored in ~/.bash_history but it's location can be controlled by setting $HISTFILE
The history file is only written when the shell exits, so you can delete the last ten lines from a history file but that might not be what you want.
You can prevent anything from being written to the history file by setting the value of $HISTSIZE to 0. Or I guess you could set $HISTFILE to /dev/null.
