CONFIGURATION

Get most of HSTR by configuring it with:

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

Run hh --show-configuration to determine what will be appended to your Bash profile.

For more configuration options details please refer to:

Check also configuration examples.

BINDING HSTR TO KEYBOARD SHORTCUT

Bash uses Emacs style keyboard shortcuts by default. There is also Vi mode. Find out how to bind HSTR to a keyboard shortcut based on the style you prefer below.

Check your active Bash keymap with:

bind -v | grep editing-mode
bind -v | grep keymap

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

bind -S

BASH EMACS KEYMAP (DEFAULT)

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 it is interactive shell:

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

You can bind also other hh commands like -kill-last-command:

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

BASH VI KEYMAP

Bind hh to a Bash key e.g. to Ctrl-r:

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

ZSH EMACS KEYMAP (DEFAULT)

Bind hh to a Zsh key e.g. to Ctrl-r:

bindkey -s "\C-r" "\eqhh --\n"

COLORS

Get hh in more colors:

export HH_CONFIG=hicolor

or ensure black and white mode:

export HH_CONFIG=monochromatic

HISTORY VIEW

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

export HH_CONFIG=rawhistory

Show favorite commands by default (instead of metrics-based view):

export HH_CONFIG=favorites

FILTERING

Make search case sensitive (insensitive by default):

export HH_CONFIG=casesensitive

Keep duplicates in rawhistory view (duplicates discarded by default):

export HH_CONFIG=duplicates

BLACKLIST

Skip commands when processing history i.e. make sure that these commands will not be shown in any view:

export HH_CONFIG=blacklist

Commands to be stored in ~/.hh_blacklist file with trailing empty line. For instance:

cd
my-private-command
ls
ll

CONFIRM ON DELETE

Do not prompt for confirmation when deleting history items:

export HH_CONFIG=noconfirm

VERBOSITY

Show a message when deleting the last command from history:

export HH_CONFIG=verbose-kill

Show warnings:

export HH_CONFIG=warning

Show debug messages:

export HH_CONFIG=debug

BASH HISTORY SETTINGS

Use the following BASH settings to get most out of hh.

Increase the size of history maintained by BASH - variables defined below increase the number of history items and history file size (default value is 500):

export HISTFILESIZE=10000
export HISTSIZE=${HISTFILESIZE}

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.

ZSH HISTORY SETTINGS

If you use zsh, set HISTFILE environment variable in ~/.zshrc:

export HISTFILE=~/.zsh_history

EXAMPLES

More colors with case sensitive search of history:

export HH_CONFIG=hicolor,casesensitive

Favorite commands view in black and white:

export HH_CONFIG=favorites,monochromatic

Keywords based search in colors with debug mode verbosity:

export HH_CONFIG=keywords,hicolor,debug
