Unique BASH history

Raw

unique-bash-history.sh

	HISTCONTROL="erasedups"
	export HISTCONTROL

You should add
shopt -s histappend
shopt -s cmdhist
bind '"\e[B": history-search-forward'
bind '"\e[A": history-search-backward'
(on top of erasedups). This is even better. Say you type
# ls
and press UP. Then UP cycles through commands starting with ls, not all commands.

For the lazy here is the combined power of @arq5x and @kasperdanielhansen:

shopt -s histappend
shopt -s cmdhist
bind '"\e[B": history-search-forward'
bind '"\e[A": history-search-backward'

HISTCONTROL="erasedups"

export HISTCONTROL
