HISTIGNORE only deals with consecutive duplicates, IIRC. What you want is: export HISTCONTROL=erasedups you might also want to add ":ignorespace" to the end of that. That will cause any command prefixed by a space to be ignored as well - very useful for those long commands that you will only ever run once!
