Delete bash history in Centos 6.2
<p>I accidentally copied a huge block of text into my Centos6.2 shell and it's annoying me in my bash history, how can I delete it?</p>

<p>I tried to run <code>history -d {{ number }}</code> but it comes back the next time I open a shell :(</p>

<p>Additionally when I tried using <code>history -d $i</code> in a for i in list loop 
, I don't think it deleted anything as they run in subshells . </p>
