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.)
