The bash default is not to set that variable.  But it looks like you
are using Ubuntu and the Ubuntu package default is to set it in the
default .bashrc file as a user level customization.

If you don't like that configuration then edit your ~/.bashrc file and
change this:

  # don't put duplicate lines or lines starting with space in the history.
  # See bash(1) for more options
  HISTCONTROL=ignoreboth

Change that to something different.  Perhaps simply ignoredups?

  HISTCONTROL=ignoredups

Or whatever you prefer there.  It is your .bashrc file.  Customize it
as you desire.
