Once in September of 2006 when the North Carolina weather was in a cusp of thundering rains and dry autums, I ventured to my kitchen to fry up some snacks. Here is the writeup on that effort and the thought proess behind the courage :)

One fine day the gods above blessed me with about 200 gms of 'Baisan'. Not to waste such a fortunate opportunity, I pondered over the best way to use this yellow, weired smelling, soft powder. My first thought was to use it on my face and get a better complexion.

You need to take care of three things,Open only one terminal for the user whose history you want to remove.Delete ~/.bash-history file.run history -c commandTa da !! I haven't seen the history coming back again ever. Back to my mischievous stuff :)
