BASH History Suggest Box - http://www.youtube.com/watch?v=sPF29NyXe2U

DESCRIPTION

A command line utility that brings improved BASH command completion
from the history. It aims to make completion easier and more efficient
than Ctrl-r.

UBUNTU INSTALLATION

• install hh on Ubuntu (12.10/13.04/13.10):

sudo add-apt-repository ppa:ultradvorka/ppa
sudo apt-get update
sudo apt-get install hh

• optionally configure hh:

hh --show-configuration >> ~/.bashrc

DOWNLOAD

SOURCE CODE INSTALLATION

• download distribution (project Releases section), expand the archive and install hh:

./configure && make && make install

• optionally configure hh:

hh --show-configuration >> ~/.bashrc

MAC OS

• install MacPorts:

http://www.macports.org

• set the environment:

env CFLAGS="-I/opt/local/include -I/usr/include" LDFLAGS="-L/opt/local/lib -L/usr/lib" ./configure

• finish the installation

make && make install

• optionally configure hh:

hh --show-configuration >> ~/.bashrc

CONFIGURATION EXPLANATION

• hh works best with the optional configuration described in this section.
  You can configure hh just by running:

hh --show-configuration >> ~/.bashrc

• bind hh to a BASH key e.g. to Ctrl-R:

bind '"\C-r": "\C-ahh \C-j"'

or Ctrl-F12:

bind '"\e[24;5~":"\C-ahh \C-j"'

To determine the character sequence emitted by a pressed key in terminal,
type Ctrl-v and then press the key. Check your current bindings using:

bind -S

• get hh in more colors:

export HH_CONFIG=hicolor

• increase the size of history:

export HISTFILESIZE=10000
export HISTSIZE=${HISTFILESIZE}

Variables defined above increase the number of history items and history file size
(default value is 500).

• ensure syncing (flushing and reloading) of .bash_history with in-memory
  history:

export PROMPT_COMMAND="history -a; history -n; ${PROMPT_COMMAND}"

• force appending of in-memory history to .bash_history
  (instead of overwriting):

shopt -s histappend

• use leading space to hide commands from history:

export HISTCONTROL=ignorespace

Suitable for a sensitive information like passwords.
