  That is just *nasty*.  For each line in the file you invoke
 a new grep...

  What about :

      sort -u < ~/.bash_history > ~/.bash_history.new

 Sure it re-orders entries, but in practice your current solution does
 too. (ie.  dupes removed between existing commands are going to affect
 the ordering of commands.)
