HISTCONTROL=ignoreboth not working in Debian Lenny

Question

Can anyone confirm if by setting the following environmental variables under Debian Lenny, it will make previous history entries not be saved? I'm using GNU bash, version 3.2.39(1)-release.

export HISTCONTROL=ignoreboth
export HISTSIZE=500

I have added them to my /etc/bash.bashrc file but I keep getting repeated commands.

Answer 1

Use erasedups instead! It work for me!

export HISTCONTROL=erasedups

If you need more options separate them with:

export HISTCONTROL=ignorespace:erasedups
