Oops, sorry 4 the snafu, couldn't cut and paste. HISTSIZE=1000 should 
work. Tuping bash at the command should reset the shell and give you 
another instance of bash?

I see the default is set as
HISTCONTROL=ignoreboth

Does one change this to

HISTCONTROL=ignoredups

or

HISTCONTROL="&"

Which is better?
