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

DESCRIPTION

Are you looking for a command that you used recently? Do you want to avoid the need to write long commands over and over again despite you used them recently? Are you looking for a tool that is able to manage your favorite commands?

HSTR is 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.

Apart to the completion, history can be managed (you can remove commands that e.g. contain sensitive information like passwords) and bookmark your favorite commands.

UBUNTU INSTALLATION

• install hh on Ubuntu (12.04LTS/12.10/13.10/14.04LTS):

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

• optionally configure hh:

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

INSTALLATION FROM SOURCE CODE

• Clone Git repository:

git clone https://github.com/dvorka/hstr.git

• create build files using:

cd ./dist && ./1-dist.sh && cd ..

• install hh using:

./configure && make && make install

• optionally configure hh:

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

DISTRIBUTION INSTALLATION

• download latest distribution from project Releases section:

https://github.com/dvorka/hstr/releases

• expand the archive and install hh using:

./configure && make && make install

• optionally configure hh:

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

DEBIAN/MINT INSTALLATION

• install hh on Debian (Wheezy) or Mint (13) by registering the key:

wget www.clfh.de/frankh.asc
apt-key add frankh.asc

adding the repository:

deb http://www.clfh.de/debian wheezy main
deb-src http://www.clfh.de/debian wheezy main

and installing it:

apt-get update
apt-get install hh

• optionally configure hh:

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

ARCH LINUX

• download latest distribution from project Releases section:

https://github.com/dvorka/hstr/releases

• use PKGBUILD in the root of the distribution to build package using makepkg:

https://wiki.archlinux.org/index.php/PKGBUILD

• install hh
• 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-Alt-r:

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

or Ctrl-F12:

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

bind hh to Ctrl-r only if this is interactive shell:

if [[ $- =~ .*i.* ]]; then bind '"\C-r": "\C-a hh \C-j"'; fi

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

show normal history by default (instead of metrics-based view):

export HH_CONFIG=rawhistory

show favorites by default (instead of metrics-based view):

export HH_CONFIG=favorites

make search case sensitive (insensitive by default):

export HH_CONFIG=casesensitive

show warnings:

export HH_CONFIG=warning

show debug messages:

export HH_CONFIG=warning

more colors and case sensitive search:

export HH_CONFIG=hicolor,casesensitive

• 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.
