We can use a bash variable HISTCONTROL to turn off duplicates in bash history. It can be one of three values:

• HISTCONTROL='ignoreups' means to not enter lines which match the last entered line
• HISTCONTROL='ignorespace' means to not enter lines which begin with a space or tab into the history list
• HISTCONTROL='ignoreboth' does both

We can export it in bashrc

export HISTCONTROL='ignoreboth';
